Article Abstract

Objective: To demonstrate how piloted flight simulation can be used to replicate rescue helicopter missions in mountainous terrain. To meet this objective, a piloted flight simulation environment has been created in which a helicopter pilot can "fly" over a mountain terrain and through realistic turbulent air flow.

Methods: A solid model, 550 metres across, of a mountainous island has been created and which contains topographic features such as a bowl, pinnacle, ridge, canyon, and cliff. The air flow over this terrain has been computed for a 20-knot wind and integrated with a helicopter flight model representative of a UH-60 Black Hawk. Using a full-motion flight simulator, two test pilots explored the island and conducted a stable hover flight test up the face of the cliff.

Results: The simulation demonstrates great promise and was judged by the test pilots to be an impressive first attempt at developing a search and rescue "training landscape." The flight test results revealed how the pilots found it difficult to maintain a stable hover when exposed to the turbulent shear layer at the top of the cliff, consistent with their real-world experience.

Conclusion: The exploratory study was considered to be successful, meriting further research and development to increase the range of wind conditions and to explore the other topographic features in the terrain.

Flexible spacecraft possess the ability to adapt to complex environments and use energy more efficiently, offering enhanced flexibility and stability in space missions, particularly in tasks with significant external disturbances such as deep space exploration and satellite attitude control. However, vibration suppression in flexible spacecraft remains a critical challenge. This study addresses the problem of vibration suppression in flexible spacecraft systems under external disturbances and input constraints.

Human factors are central to aviation safety, with pilot cognitive states such as workload, stress, and situation awareness playing important roles in flight performance and safety. Although flight simulators are widely used for training and scientific research, they often lack the ecological validity needed to replicate pilot cognitive states from real flights. To address these limitations, a new in-flight data collection methodology for general aviation using a Cessna 172 aircraft, which is one of the most widely used aircraft for pilot training, is presented.

A novel practical predefined-time sliding mode control strategy is proposed for the flight formation of a small tandem-rotor wheeled UAV (TRW-UAV) with unknown upper bound external disturbances and uncertainties in this paper. Firstly, a new predefined-time sliding mode surface is proposed to guide all errors of the position and velocity loops to converge to the origin in a predefined-time. Furthermore, a dynamic surface control approach is utilized to circumvent the higher-order differentiation when controlling the actuator loop.

Introduction: A 264-d isolation simulation, SFINCSS-99, was conducted in Moscow to replicate typical scenarios on an orbital space station. One long-term group of four Russian crewmembers occupied the isolation complex for most of the duration (240 d), while two international groups of four each spent 110 d successively at the complex. Additionally, there were several short visits by medical personnel.
