Abstract Recoil reduction is one of the most important issues for design aircraft gun. Traditional approaches this purpose will produce back-blast, which constitutes a hazard to fighter planes or attack helicopters. This paper presents closed type gas reflection device gun aiming reduce recoil force without ejecting propellant rearward. The launching process modeled by coupling classical interi...

In order to meet requirement of indexes demonstration at fighter design’s early stage, a mission simulation-based fighter anti-ship effectiveness evaluation method on stealth capability is researched. Evaluation indexes for the mission which can be divided into parameter indexes and mission indexes are proposed. The architecture of the simulation system which includes database, computation modu...

In a dynamic, multi-agent environment, an the intelligent agents act as automated pilots automated intelligent agent is often faced with the for the simulated aircraft. These automated possibility that other agents may instigate events that pilots will take part in exercises with human actually hinder or help the achievement of its own goals. fighter pilots, where they will aid in tactics To ac...

Suppose that a circular fire spreads in the plane at unit speed. A single fire fighter can build a barrier at speed v > 1. How large must v be to ensure that the fire can be contained, and how should the fire fighter proceed? We contribute two results. First, we analyze the natural curve FFv that develops when the fighter keeps building, at speed v, a barrier along the boundary of the expanding...

The objective of this research is to investigate smart actuator technology for an adaptive neck brace to assist pilots during high g+ maneuvers. Analysis and experiments were conducted to develop a simplified analytical model of the neck, determine the effectiveness of using a brace to prevent neck injury under high acceleration loads, identify actuator technology capable of actuating the mecha...

The advent of advanced development in sensors, microelectronics, adaptive signal processing and predictive technologies have significantly shaped the fundamental approach to dealing with traditional maintenance and repair problems within the aerospace industry. The concept of aircraft Diagnostics, Prognostics and Health Management (DPHM) is increasingly becoming a main stream approach to dealin...
