The entire range of services also includes structural components, such as belly fairings, pressure bulkheads, pressurised floors, support constructions, RAT frames, landing flaps, lighting covers, ram-air outlets, APU compartments and also fuel tanks. The full monocoque fuselage has fewer internal parts and a more highly stressed skin than the semimonocoque fuselage, which uses internal bracing to obtain its strength. The earliest aircraft of all, of course, is the Wright Flyer (1903) Its main structural characteristics include: Biplane main wing, canard, rudder and fore/aft fuselage all use similar structural arrangement of rectangular trussed sections comprising: The substructure, which consists of bulkheads and/or formers of various sizes and stringers, reinforces the stressed skin by taking some of the bending stress from the fuselage. Main structural component that houses crew and cargo. 1. Many aircraft use the inside wing area for gas tank mounting – since this is the safest (stiffest and strongest) part of the entire plane. What is a Truss Fuselage? For example, the wing of the weight-shift control aircraft is highly swept in an effort to reduce drag and allow for the shifting of weight to provide controlled flight.

AIRCRAFT STRUCTURAL. function copyrightDate() // Defect and failure investigations on aircraft structural components have an important role in improving aircraft safety. The largest of the aircraft structural components, there are two types of metal aircraft fuselages: Full monocoque and semimonocoque. PLAY. There are two general types of fuselage construction, the truss type, and the monocoque type. Advises on structural and low observable repair, modification, and corrosion protection treatment with respect to original strength, weight, and contour to maintain structural and low observable integrity. Such designs are usually referred to as stabilators, flying tails, or slab tails, The empennage, then, provides the airplane with directional and longitudinal balance (stability) as well as a means for the pilot to control and maneuver the airplane, Rudders are used to control the direction (left or right) of "yaw" about an airplane's vertical axis, Like the other primary control surfaces, the rudder is a movable surface hinged to a fixed surface that, in this case, is the vertical stabilizer, or fin, Its action is very much like that of the elevators, except that it swings in a different plane - from side to side instead of up and down, It is not used to make the airplane turn, as is often erroneously believed, In practice, both aileron and rudder control input are used together to turn an aircraft, the ailerons imparting roll, This relationship is critical in maintaining coordination or creating a slip, Improperly ruddered turns at low speed can precipitate a spin. Includes aircraft structural component support and more. TEG understands that component reliability and time on wing is critical to keeping your aircraft in the air. FSG 15 - Aircraft & Airframe Structural Components Sourcing for NSN parts, military components and materials, electronic and aircraft components as well as electro-mechanical parts and hardware. A typical semi-monocoque fuselage consists of the following elements: Stringers or Longerons. Aircraft’s fuselage includes stringers, longerons, ribs, bulkheads. Older types of aircraft design utilized an open truss structure constructed of wood, steel, or aluminum tubing. Need some help? Stabilators have an antiservo tab extending across their trailing edge [Figure 3-11], The anti-servo tab moves in the same direction as the trailing edge of the stabilator and helps make the stabilator less sensitive, The anti-servo tab also functions as a trim tab to relieve control pressures and helps maintain the stabilator in the desired position, Flight control surfaces consist of primary, secondary, and auxiliary controls [, Tabs are small, adjustable aerodynamic devices on the trailing edge of the control surface, These movable surfaces reduce pressures on the controls, Trim controls a neutral point, like balancing the aircraft on a pin with unsymmetrical weights, This is done either by trim tabs (small movable surfaces on the control surface) or by moving the neutral position of the entire control surface all together, These tabs may be installed on the ailerons, the rudder, and/or the elevator, The force of the airflow striking the tab causes the main control surface to be deflected to a position that corrects the unbalanced condition of the aircraft, An aircraft properly trimmed will, when disturbed, try to return to its previous state due to, Trimming is a constant task required after any power setting, airspeed, altitude, or configuration change, Proper trimming decreases pilot workload allowing for attention to be diverted elsewhere, especially important for instrument flying, Trim tabs are controlled through a system of cables and pulleys, Trim tab adjusted up: trim tab lowers creating positive lift, lowering the nose, Trim tab adjusted down: trim tab raises creating positive lift, raising the nose, To learn more about how to use the trim tab in flight see the, Servo tabs are similar to trim tabs in that they are small secondary controls which help reduce pilot workload by reducing forces, The defining difference however, is that these tabs operate automatically, independent of the pilot, Also called an anti-balance tab, are tabs that move in the same direction as the control surface, Tabs that move in the opposite direction as the control surface, Attached to the leading edge of the wings and are designed to be controlled by the pilot or automatically by the flight computer, Slats increase the camber of the wings/airfoil, By extending the slats additional lift is created when the aircraft is at slower airspeeds, normally on takeoff and landing, Attached to the trailing edge of the wings and are controlled by the pilot from the cockpit, By extending the flaps additional lift is created when the aircraft is at slower airspeeds, normally on takeoff and landing, Slats and flaps are used in conjunction with each other to increase both lift and stall margin by increasing the overall wings camber thus, allowing the aircraft to maintain control flight at slower airspeeds, Flaps extend outward from the fuselage to near the midpoint of each wing, The flaps are normally flush with the wing's surface during cruising flight, When extended, the flaps move simultaneously downward to increase the lifting force of the wing for takeoffs and landings [Figure 3-8], The elevators are attached to the horizontal portion of the empennage - the horizontal stabilizer, The exception to this is found in those installations where the entire horizontal surface is a one piece structure which can be deflected up or down to provide longitudinal control and trimming, A change in position of the elevators modifies the camber of the airfoil, which increases or decreases lift, When forward pressure is applied on the controls, the elevators move downward, This increases the lift produced by the horizontal tail surfaces, The increased lift forces the tail upward, causing the nose to drop, Conversely, when back pressure is applied on the wheel, the elevators move upward, decreasing the lift produced by the horizontal tail surfaces, or maybe even producing a downward force, The tail is forced downward and the nose up, The elevators control the angle of attack of the wings, When back-pressure is applied on the controls, the tail lowers and the nose rises, increasing the angle of attack, Conversely, when forward pressure is applied, the tail raises and the nose lowers, decreasing the angle of attack, Designed to slow the aircraft when in a dive or descent, location and style vary with aircraft, and are controlled by a switch in the cockpit, Movable tabs located on the primary control surfaces i.e., ailerons, elevators and rudder reducing the pilot's workload enabling the aircraft to hold a particular attitude without the need of constant pressure/inputs into the system, The landing gear is the principal support of the airplane when parked, taxiing, taking off, or landing, A steerable nosewheel or tailwheel permits the airplane to be controlled throughout all operations while on the ground, Most aircraft are steered by moving the rudder pedals, whether nosewheel or tailwheel, Additionally, some aircraft are steered by differential braking, The powerplant usually includes both the engine and the propeller, The primary function of the engine is to provide the power to turn the propeller, It also generates electrical power, provides a vacuum source for some flight instruments, and in most single-engine airplanes, provides a source of heat for the pilot and passengers [, On single engine airplanes the engine is usually attached to the front of the fuselage, There is a fireproof partition between the rear of the engine and the cockpit or cabin to protect the pilot and passengers from accidental engine fires. ///////////////////////////////// Includes aircraft skin, aircraft spar, longeron, aircraft bulkhead and more. 1.5 Air … The major aircraft structural components are wings, fuselage, and empennage.

Copyright © STUDY. These parts are connected by seams, called joints. Would you like a visit to discuss your requirements? ///////////////////////////////// [Figure 3-9] Handbooks specific to most categories of aircraft are available for the interested pilot and can be found on the Federal Aviation Administration (FAA) website at www.faa.gov, Ailerons (French for "little wing") are control surfaces on each wing which control the aircraft about its longitudinal axis allowing the aircraft to "roll" or "bank", This action results in the airplane turning in the direction of the roll/bank, With aileron deflection, there is an asymmetrical lift (rolling moment) about the longitudinal axis and drag (, They are located on the trailing (rear) edge of each wing near the outer tips, They extend from about the midpoint of each wing outward toward the tip, and move in opposite directions to create aerodynamic forces that cause the airplane to roll, The yoke manipulates the airfoil through a system of cables and pulleys and act in an opposing manor, Yoke "turns" left: left aileron rises, decreasing camber and angle of attack on the right wing which creates downward lift, At the same time, the right aileron lowers, increasing camber and angle of attack which increases upward lift and causes the aircraft to turn left, Yoke "turns" right: right aileron rises decreasing camber and angle of attack on the right wing which creates downward lift, At the same time, the left aileron lowers, increasing camber and angle of attack on the left wing which creates upward lift and causes the aircraft to turn right, Although uncommon, some ailerons are configured with trim tabs which relieve pressure on the yoke on the aileron for rolling, The shape and design of a wing is dependent upon the type of operation for which an aircraft is intended and is tailored to specific types of flying: [, Rectangular wings are best for training aircraft, as well as low speed aircraft, Elliptical wings are most efficient, but difficult to produce (spitfire), More efficient than a rectangle wing but easier to produce than an elliptical design, Usually associated with swept-back, but can also be swept-foreword, Sweptback wings are best for high speed aircraft for delaying Mach tendencies, Stall at the tips first, providing poor stall characteristics, Advantages of a swept wing, with good structural efficiency and low frontal area, Disadvantages are the low wing loading and high wetted area needed to obtain aerodynamic stability, These design variations are discussed in Chapter 5, Aerodynamics of Flight, which provides information on the effect controls have on lifting surfaces from traditional wings to wings that use both flexing (due to billowing) and shifting (through the change of the aircraft's CG). A truss is a rigid framework made up of members such as beams, struts, and bars to resist deformation by applied loads. There is a fireproof partition between the rear of the engine and the flight deck or cabin to protect the pilot and passengers from accidental engine fires. It reflects the interrelationships between stress level (S, in MPa), fatigue life (N f, in flight hours), and calendar life (N y, in years).When an aircraft is used so heavily that it exceeds the limits of ASELS, the structural state is considered to be unsafe. As with all other aspects involved with an aircraft, the structural design and layout has changed markedly over the history of flight, in line with technological advances and new discoveries. These issues are developed in some detail in subsequent chapters on steady turning flight. Aug 19, 2019 - Explore Robert McSpadden's board "Aircraft Structural Components" on Pinterest. AerSale Component Solutions specializes in the MRO of composite and mechanical airframe components. [Figure 3-9] Handbooks specific to most categories of aircraft are available for the interested pilot and can be found on the Federal Aviation Administration (FAA) website at www.faa.gov, Commonly known as the "tail section," the empennage includes the entire tail group which consists of fixed surfaces such as the vertical fin or stabilizer and the horizontal stabilizer; the movable surfaces including the rudder and rudder trim tabs, as well as the elevator and elevator trim tabs, These movable surfaces are used by the pilot to control the horizontal rotation (yaw) and the vertical rotation (pitch) of the airplane, In some airplanes the entire horizontal surface of the empennage can be adjusted from the cockpit as a complete unit for the purpose of controlling the pitch attitude or trim of the airplane. When any component or group of components has been damaged, it is essential that both the damaged members and the attaching structure be investigated, since the damaging force may have been transmitted over a large area, sometimes quite remote from the point of original damage.
