This paper deals with the simulation of landing gear semi-active control for a small trainer aircraft in a multibody framework. The behavior of single passive landing gear drop test simulation models and of a complete aircraft landing simulation model, developed and implemented in the commercial multibody code ADAMS in previous works, is compared to the that of analogous models equipped with se...

guidance and control of aircraft in the landing phase imposes extra pilot work loads, hence application of automatic landing control systems is of great importance. in this study automatic landing control systems are introduced and an optimal landing control system is designed. the control system performance criteria are based on minimum control effort. the designed system is simulated for a tr...

In modern fighter aircraft, several fully automatic or semi-automatic support systems have been implemented so as to aid the pilots in performing their tasks and accomplishing their missions. However, both positive and negative effects of automation have been reported. Amongst the positive effects, decreased physical workload and increased situation awareness have been documented. Amongst the n...

A consultation was undertaken to investigate the views and concerns of stakeholders in the aircraft industry about the possible harmful effects on personal health, comfort and safety of aircraft cabin environments. Stakeholders were identified from a variety of sources including Government agencies, the Internet, House of Lords inquiry, and suggestions of interviewees. They represented: aircraf...

This paper describes the development of a large 35%-scale unmanned aerobatic platform named the UIUC Aero Testbed, which is primarily intended to perform aerodynamics research in the full flight regime. The giant-scale aircraft with a 105-in (2.7-m) wingspan and weight of 37 lb (17 kg) was constructed from a commercially available radio control model aircraft with extensive modifications and up...

A detailed assessment of the acoustic performance of several noise reduction concepts for aircraft flaps and landing gear is presented. Consideration is given to the best performing concepts within the suite of technologies that were evaluated in the NASA Langley Research Center 14by 22-Foot Subsonic Tunnel using an 18% scale, semi-span, high-fidelity Gulfstream aircraft model as a test bed. Mi...

Effective team work is regarded as a key factor for success inmissions performed by fighter aircraft in a Tactical Air Unit (TAU). Manyfactors contribute to how a team will succeed in their mission. From the existingliterature on teamwork, Salas, Sims and Burke [1], suggested five main factorsand three supporting mechanisms for effective team work. These were proposedas the ...

In this paper, the maximum take-off mass (MTOM) of a 19-seat fuel cell aircraft with similar characteristics to conventional is estimated using combination rapid method and semi-empirical equations. The study shows that MTOM current technology would be 25% greater than aircraft. However, expected technological improvements, could reach lower values most important parameter affecting power-to-we...

Monitoring of semi-autonomous systems increases situational awareness and is highly applicable to small remotely piloted aircraft. The complex dynamics of aircraft flight were abstracted by modeling the system with a neural network. The neural network accurately modeled the non-faulty dynamics for comparison to the actual system. Since, the system included unmodeled lag, the residual calculatio...
