Flight vehicle

Plastics have found numerous uses in specialty areas such as hypersonic atmospheric flight and chemical propulsion exhaust systems. The particular plastic employed in these applications is based on the inherent properties of the plastics or the ability to combine it with another component material to obtain a balance of properties uncommon to either component. Some of the compositions and important properties of plastics are given in Tables 2-9 and 2-10 that have been developed over the years for use in flight vehicles and propulsion systems that are dependent upon chemical, mechanical, electrical, nuclear, and solar means for accelerating the working fluid by high temperatures.

The wind tunnel is most frequently employed for this purpose. Perfect simulation is impossible, however, and thus the choice of facility is dictated by the importance of closely simulating either the thermal, chemical, or mechanical aspects of the entry environment. Subsequent specialized testing is then carried out to determine the importance of environmental parameters not closely simulated in the previous evaluation work. Finally, the plastic material is flown in the actual service environment to prove its heat shielding effectiveness, confirm previous theoretical prediction of material behavior, and to provide a sound basis for the selection and design of heat shields for operational flight vehicles.

Aeronautics is the science of atmospheric flight. Aviation is the design, development, production, and operation of flight vehicles. Aerospace engineering extends these fields to space vehicles. Transonic airliners, airships, space launch vehicles, satellites, helicopters, interplanetary probes, and fighter planes are all applications of aerospace engineering.

Aeroelastic and vibration control technology allows flight vehicles to operate beyond the traditional flutter boundaries, improves ride qualities, and minimizes vibration fatigue damage. Conventional active flutter and vibration control technology relies on the use of aerodynamic control surfaces operated by servo-hydraulic actuators. In this conventional configuration, the... 

Ablative systems are not limited by the heating rate or environmental temperature, but rather by the total heat load. In spite of this limitation, however, the versatility of ablation has permitted it to be used on almost every recent hypervelocity atmospheric vehicle. Moreover, it appears that ablation will continue to be favored as the primary thermal protection method for future flight vehicles. 

Recent advances in motion-capture technology combined with continued developments in small-scale electronics can enable the rapid design and evaluation of flight vehicle concepts (Troy et al, 2007). These evaluations can be extended to the mission level with additional vehicles and associated software. 

Screen channel LADs have a rich flight heritage with storable propellants. They have been used in both space experiments and flight vehicles. Design of these LADs is well understood for storable systems (Schweickert, 1981 Anglim, 1981 Rollins et al., 1988). Galleries have particular success in missions which require flexible demand systems, such as the STS.
