The dynamic response of an integrated aircraft-floating structure-water interaction system excited by the impact of a landing aircraft is investigated. The aircraft and the floating structure are considered 2 elastic substructures, and the water is treated as a fluid subdomain. The landing gears of the aircraft are modeled by 3 supporting systems, each consisting of a spring and a damper. A mix...

With the development of modern military ship equipment, airspace operation environment shipboard aircraft is becoming increasingly complex. The objective and accurate evaluation ship-terminal capacity basis air traffic flow management for aircraft, it also premise improving efficiency resources. First all, this paper divides terminal areas realizes route network planning arrival departure aircr...

Contrary to the popular views, air travel has been the safest compared to other surface transportation (automobile & railroad) in terms of casualty of passengers. This is mainly due to the vigilant pursuit of safety margin in the design of Air Traffic Control and Navigation (ATCN) system. However, the rising demand of air travels requires us to review the safety factor affecting all phases of a...

Considerable progress has been made over the last 15 years on building adaptive control systems to assist pilots in flying damaged aircraft. Once a pilot has regained control of a damaged aircraft, the next problem is to determine the best site for an emergency landing. In general, the decision depends on many factors including the actual control envelope of the aircraft, distance to the site, ...

A manned or unmanned helicopter-ship qualification program (Dynamic Interface Testing) evaluates, improves, and/or develops all aspects of shipboard helicopter compatibility. Issues addressed during a test may include the adequacy, effectiveness, and safety of shipboard aviation support facilities and helicopter recovery procedures. Manned and unmanned aircraft share a number of common issues a...

This paper focuses on a novel morphing aircraft capability called perching: the ability of an aircraft to make a planted landing using primarily aerodynamic forces in lieu of high thrust. Specifically, the modeling of the perching aircraft’s aerodynamics and the problem of computing and optimizing a perching trajectory using this model are presented. The aerodynamic model discussed herein is de...

This paper presents an assertional-style verification of the aircraft landing protocol of NASA’s SATS (Small Aircraft Transportation System) concept [1] using the I/O automata framework and the PVS theorem prover. We reconstructed the mathematical model of the landing protocol presented in [2] as an I/O automaton. In addition, we translated the I/O automaton into a corresponding PVS specificati...

This paper studies the multiple runway aircraft landing problem. The aim is to schedule arriving aircraft to available runways at the airport. Landing times lie within predefined time windows and safety separation constraints between two successive landings must be satisfied. We propose a new approach for solving the problem. The method is based on an approximation of the separation time matrix...

A concept of the perch landing assisted by thruster (PLAT) for a fixed wind aircraft is proposed in this paper. The proposed concept is applicable to relatively large unmanned aerial vehicles (UAV), hence can overcome the limitation of existing perch landing technologies. A planar rigid body motion of an aircraft with aerodynamic and thruster forces and moments is modeled. An optimal control pr...
