FAA - A History of Helicopter Structures Facts for Anchorage

A steady increase in the use of honeycomb and foam core sandwich components and a wide variety of composite materials characterizes the state of aviation structures from the 1970s to the present. Advanced techniques and material combinations have resulted in a gradual shift from aluminum to carbon fiber and other strong, lightweight materials. These new materials are engineered to meet specific performance requirements for various components on the aircraft.

Many airframe structures are made of more than 50 percent advanced composites, with some airframes approaching 100 percent. The term “very light jet” (VLJ) has come to describe a new generation of jet aircraft made almost entirely of advanced composite materials. [Figure 1-10] It is possible that non-composite aluminum aircraft structures will become obsolete as did the methods and materials of construction used by Cayley, Lilienthal, and the Wright Brothers.

Huey History

Bell Helicopters built 10,005 Hueys from 1957 to 1975. Prior to 1957 there were three XH-40 prototypes and six YH-1B test helicopters manufactured. Of the 10,005 production Huey's the first 732 were designated HU-1A and HU-1B. 9,216 of these went to the US Army, 79 to the US Air Force, 42 to the Navy, and 127 to the Marine Corps. The rest went to other countries.

it may help to travel back to the earliest days of powered aviation, to fully understand fixed wing aircraft. The Wright brothers created the first plane which utilized the fixed wing design.

The total helicopter pilots killed in the Vietnam War was 2,202. Total non-pilot crew members was 2,704. Based on a database from the Pentagon we estimate that over 40,000 helicopter pilots served in the Vietnam War.

A standard fixed wing aircraft has a curved upper surface and a flat lower surface. When the propeller or jet engine pushes the entire airplane forward, the air strikes the front edge of the wing with substantial pressure, and in general, gives it lift.

Airframe structural components are constructed from a wide variety of materials. The earliest aircraft were constructed primarily of wood. Steel tubing and the most common material, aluminum, followed. Many newly certified aircraft are built from molded composite materials, such as carbon fiber. Structural members of an aircraft’s fuselage include stringers, longerons, ribs, bulkheads, and more. The main structural member in a wing is called the wing spar.

The skin of aircraft can also be made from a variety of materials, ranging from impregnated fabric to plywood, aluminum, or composites. Under the skin and attached to the structural fuselage are the many components that support airframe function. The entire airframe and its components are joined by rivets, bolts, screws, and other fasteners. Welding, adhesives, and special bonding techniques are also used.

Helicopter Facts for Fort Richardson

The Germans used helicopters for artillery spotting on the Russian front in WWII. The Germans also built and perfected a rotor-kite (helicopter with no engine) that was towed behind a U-Boat to increase the range at which targets could be spotted. (Since it had no power, there was no torque, and no need for a tailrotor.)

Aircraft structural members are designed to carry a load or to resist stress. In designing an aircraft, every square inch of wing and fuselage, every rib, spar, and even each metal fitting must be considered in relation to the physical characteristics of the material of which it is made. Every part of the aircraft must be planned to carry the load to be imposed upon it.

Aerodynamics and the Laws of Physics

The law of conservation of energy states that energy may neither be created nor destroyed. Motion is the act or process of changing place or position. An object may be in motion with respect to one object and motionless with respect to another. For example, a person sitting quietly in an aircraft flying at 200 knots is at rest or motionless with respect to the aircraft; however, the person and the aircraft are in motion with respect to the air and to the earth.

USARAK's mission is to be prepared to deploy rapidly in the Pacific theater and elsewhere in support of contingency operations, USPACOM objectives

Helicopter Facts for Homer

On twin-rotor craft the rotors spin in opposite directions, so their reactions cancel each other. The helicopter is propelled in a given direction by inclining the axis of the main rotor in that direction. The helicopter's speed is limited by the fact that if the blades rotate too fast they will produce compressibility effects on the blade moving forward and stall effects on the rearwardmoving blade, at the same time.

FAA - A History of Aircraft Structures Factoid for Homer

In 1909, Frenchman Louis Bleriot produced an aircraft with notable design differences. He built a successful mono-wing aircraft. The wings were still supported by wires, but a mast extending above the fuselage enabled the wings to be supported from above, as well as underneath. This made possible the extended wing length needed to lift an aircraft with a single set of wings. Bleriot used a Pratt truss-type fuselage frame.

FAA - A History of Aircraft Structures Factoid for Houston

Leading up to World War I (WWI), stronger engines also allowed designers to develop thicker wings with stronger spars. Wire wing bracing was no longer needed. Flatter, lower wing surfaces on high-camber wings created more lift. WWI expanded the need for large quantities of reliable aircraft. Used mostly for reconnaissance, stacked-wing tail draggers with wood and metal truss frames with mostly fabric skin dominated the wartime sky.

FAA - A History of Aircraft Structures Factoid for Houston

More powerful engines were developed, and airframe structures changed to take advantage of the benefits. As early as 1910, German Hugo Junkers was able to build an aircraft with metal truss construction and metal skin due to the availability of stronger powerplants to thrust the plane forward and into the sky. The use of metal instead of wood for the primary structure eliminated the need for external wing braces and wires. His J-1 also had a single set of wings (a monoplane) instead of a stacked set.

FAA - A History of Aircraft Structures Factoid for Juneau

In the 1920s, the use of metal in aircraft construction increased. Fuselages able to carry cargo and passengers were developed. The early flying boats with their hull-type construction from the shipbuilding industry provided the blueprints for semimonocoque construction of fuselages. Truss-type designs faded. A tendency toward cleaner mono-wing designs prevailed.

FAA - A History of Aircraft Structures Factoid for Juneau

Into the 1930s, all-metal aircraft accompanied new lighter and more powerful engines. Larger semimonocoque fuselages were complimented with stress-skin wing designs. Fewer truss and fabric aircraft were built. World War II (WWII) brought about a myriad of aircraft designs using all metal technology. Deep fuel-carrying wings were the norm, but the desire for higher flight speeds prompted the development of thin-winged aircraft in which fuel was carried in the fuselage. The first composite structure aircraft, the De Havilland Mosquito, used a balsa wood sandwich material in the construction of the fuselage. The fiberglass radome was also developed during this period.

FAA - A History of Aircraft Structures Factoid for Kalifornsky

After WWII, the development of turbine engines led to higher altitude flight. The need for pressurized aircraft pervaded aviation. Semimonocoque construction needed to be made even stronger as a result. Refinements to the all-metal semimonocoque fuselage structure were made to increase strength and combat metal fatigue caused by the pressurization-depressurization cycle.

FAA - A History of Aircraft Structures Factoid for Kalifornsky

In the 1960s, ever larger aircraft were developed to carry passengers. As engine technology improved, the jumbo jet was engineered and built. Still primarily aluminum with a semimonocoque fuselage, the sheer size of the airliners of the day initiated a search for lighter and stronger materials from which to build them. The use of honeycomb constructed panels in Boeing’s airline series saved weight while not compromising strength. Initially, aluminum core with aluminum or fiberglass skin sandwich panels were used on wing panels, flight control surfaces, cabin floor boards, and other applications.

FAA - A History of Aircraft Structures Factoid for Kenai

Powered heavier-than-air aviation grew from the Wright design. Inventors and fledgling aviators began building their own aircraft. Early on, many were similar to that constructed by the Wrights using wood and fabric with wires and struts to support the wing structure.

The work of all of these men was known to the Wright Brothers when they built their successful, powered airplane in 1903. The first of its kind to carry a man aloft, the Wright Flyer had thin, cloth-covered wings attached to what was primarily truss structures made of wood. The wings contained forward and rear spars and were supported with both struts and wires. Stacked wings (two sets) were also part of the Wright Flyer.

Octave Chanute, a retired railroad and bridge engineer, was active in aviation during the 1890s. His interest was so great that, among other things, he published a definitive work called “Progress in Flying Machines.” This was the culmination of his effort to gather and study all the information available on aviation. With the assistance of others, he built gliders similar to Lilienthal’s and then his own. In addition to his publication, Chanute advanced aircraft structure development by building a glider with stacked wings incorporating the use of wires as wing supports.

Helicopter Facts for Knik-Fairview

Best known among its developers are the French inventor Louis Breguet and the engineers Igor Sikorsky of the United States and Juan de la Cierva of Spain. The helicopter has become very popular for short-distance transportation, because of its maneuverability and ability to land and take off in small areas; it has been adopted for a wide range of services, including air-sea rescue, fire fighting, traffic control, oil platform resupply, and business transportation.

Aviation Facts - Stability and Control of an Aircraft

An aircraft must have sufficient stability to maintain a uniform flightpath and recover from the various upsetting forces. Also, to achieve the best performance, the aircraft must have the proper response to the movement of the controls. Control is the pilot action of moving the flight controls, providing the aerodynamic force that induces the aircraft to follow a desired flightpath. When an aircraft is said to be controllable, it means that the aircraft responds easily and promptly to movement of the controls. Different control surfaces are used to control the aircraft about each of the three axes. Moving the control surfaces on an aircraft changes the airflow over the aircraft’s surface. This, in turn, creates changes in the balance of forces acting to keep the aircraft flying straight and level.

FAA and Mitigation of the Impact of Weather

How the FAA mitigates the impact of weather. FAA air traffic controllers can’t control Mother Nature, but they have a wide range of tools to mitigate Mother Nature’s impact on the flying public. These tools are used at the agency’s Command Center in Warrenton, VA, which balances air traffic demand with system capacity on a nationwide scale, at Air Route Traffic Control Centers (ARTCC), which handle high altitude traffic, at Terminal Radar Approach Control (TRACON) facilities, which handle traffic around busy airports, and at airport towers.

Helicopter History for Kodiak

In the 1880s, the well-known scientist and inventor Thomas Edison experimented with small helicopter models. He tested several rotor configurations driven by a gun cotton engine, which was an early form of internal combustion engine. A series of explosions and other mishaps deterred further experiments with these engines. Later, Edison used an electric motor for power, and he was one of the first to realize from his experiments the need for a large diameter rotor with low blade area to give good hovering efficiency. Unlike other inventors of the times, Edison's more scientific approach to the vertical flight problem proved that both high aerodynamic efficiency of the rotor and high power from an engine were required if successful flight was to be achieved.

First Flights of Helicopters

In 1907, about four years after the Wright brothers' first successful powered flights in fixed-wing airplanes at Kitty Hawk in the United States, a French bicycle make named Paul Cornu constructed a vertical flight machine that was reported to have carried a human off the ground for the first time. The airframe was very simple, with a rotor at each end. Power was supplied to the rotors by a gasoline motor and belt transmission. Each rotor had two relatively large but low aspect ratio blades set at the periphery of a large spoked wheel. The rotors rotated in opposite directions to cancel torque reaction. The 24-hp engine used in the machine was hardly powerful enough to have sustained hovering flight out of ground effect.

The FAA World From The Perspective of Air Traffic

At any given moment there are approximately 5,000 aircraft traversing the U.S. skies.The FAA is a year-round, 24/7 operation, responsible for 5.3 million square miles of U.S. domestic airspace and 24 million square miles of U.S. airspace over the oceans. There are 43,290 average daily flights in and out of the U.S. More than 14,000 air traffic controllers manage traffic from many of the FAA’s 700 facilities. Fifty-five hundred airway transportation system specialists maintain more than 70,000 pieces of equipment.Aviation contributes $1.6 trillion annually to the U.S. economy and constitutes 5.1 percent of the gross domestic product. Aviation generates 10 million jobs in the U.S. annually.

Historical Facts of Helicopters

In 1907, the Breguet Brothers built their first helicopter. Their cumbersome quad-rotor Gyroplane consisted of four long girders made of steel tubes and arranged in the form of a horizontal cross. A rotor consisting of four biplane blades was placed at each of the four corners of the cross, giving a total of 32 separate lifting surfaces. The pilot sat in the center of the cross next to a 40-hp engine. The machine is reported to have carried a pilot off the ground, albeit briefly.

Aerodynamics and the Laws of Physics

Air has no force or power, except pressure, unless it is in motion. When it is moving, however, its force becomes apparent. A moving object in motionless air has a force exerted on it as a result of its own motion. It makes no difference in the effect then, whether an object is moving with respect to the air or the air is moving with respect to the object. The flow of air around an object caused by the movement of either the air or the object, or both, is called the relative wind.

How the FAA Mitigates the Impact of Bad Weather

They include ground stops, which keep aircraft on the ground when air traffic control is unable to safely accommodate additional aircraft in the system, ground delays, in which aircraft are delayed at their departure airport in order to manage demand and capacity at their arrival airport, and Severe Weather Avoidance Plans, which minimize the impact of a large scale storm by easing traffic demand in portions of airspace impacted by the storm. Other tools include:

- The Airspace Flow Program which identifies aircraft scheduled to fly through severe weather and provides new estimated departure times, giving airlines the flexibility to accept the delay, fly around the storm or cancel the flight.

Fixed-Wing Aircraft Factoid

Fuselage: The fuselage is the main structure or body of the fixed-wing aircraft. It provides space for cargo, controls, accessories, passengers, and other equipment. In single-engine aircraft, the fuselage houses the powerplant. In multiengine aircraft, the engines may be either in the fuselage, attached to the fuselage, or suspended from the wing structure. There are two general types of fuselage construction: truss and monocoque.

Heliports: A heliport is a type of airfield devoted to use by helicopters exclusively. Consisting of many helipads and hangers used to protect the helicopters from the elements, helicopters are able to avoid the confined and typically crowded airspace associated with a common airport.

The Aviation Maintenance Technician Handbook—Airframe (FAA-H-8083-31A) is one of a series of three handbooks for persons preparing for certification as an airframe or powerplant mechanic. It is intended that this handbook provide the basic information on principles, fundamentals, and technical procedures in the subject matter areas relating to the airframe rating. It is designed to aid students enrolled in a formal course of instruction, as well as the individual who is studying on his or her own. Since the knowledge requirements for the airframe and powerplant ratings closely parallel each other in some subject areas, the chapters which discuss fire protection systems and electrical systems contain some material which is also duplicated in the Aviation Maintenance Technician Handbook—Powerplant (FAA-H-8083-32A).

The Aviation Maintenance Technician Handbook

This volume contains information on airframe construction features, assembly and rigging, fabric covering, structural repairs, and aircraft welding. The handbook also contains an explanation of the units that make up the various airframe systems. Because there are so many different types of aircraft in use today, it is reasonable to expect that differences exist in airframe components and systems.
