Described is a method for determining a semi-empirical, equivalent simple-source model that accounts for the aeroacoustic sources in the jet plumes of high-performance military aircraft. The characteristics of the equivalent source are guided by previously reported observations of jet noise, including an asymmetric, partially correlated source distribution and known far-field peak directivity a...

In past, the aircraft control systems were based on conventional methods of mechanical and hydro-mechanical system. The present generation aircraft are using fly-by-wire (FBW) and in future likely to migrate to fly-by-light (FBL) method for aircraft control system. Mechanical & Hydromechanical flight control systems have been replaced by FlyBy-Wire due to increasing speed of modern aircraft. Du...

Aircraft survivability is a key metric that contributes to the overall system effectiveness of military aircraft as well as to a lower life cycle cost. The aircraft designer, thus, must have a complete and thorough understanding of the interrelationships between the components of survivability and the other traditional disciplines as well as how they affect the overall life cycle cost of the ai...

Multi-agent simulations are finding application in an increasing number of areas over a wide spectrum of disciplines. In recent years, the application of multi-agent systems to problems in the military has received a proportional amount of interest. However, the military analysis community is in its infancy with respect to multiagent simulations, and the efforts thus far have involved relativel...

We formulate and solve aircraft-routing problems that arise when planning missions for military aircraft that are subject to ground-based threats such as surface-to-air missiles. We use a constrained-shortest path (CSP) model that discretizes the relevant airspace into a grid of vertices representing potential waypoints, and connects vertices with directed edges to represent potential flight se...

The imaging technique of X-ray radiography is useful for the inspection of parts used in military aircraft. Given a source/detector/object configuration, a two-dimensional radiographic image is collected. Using a series of these images, a three-dimensional image of a part is constructed in which defects can be detected. The inverse problem of interest is to estimate, to an arbitrarily high degr...

This paper provides information on the design of an On Board Oxygen Generating System (OBOGS) for military aircrafts. It explains the physiological oxygen requirements of the human body in both a normal environment and in a hypoxic environment. It also includes an overview of gaseous oxygen system and liquid oxygen systems. A basic understanding of how each system operates is then specifically ...
