ABSTRACT
Stealth aircraft are aircraft that use stealth technology to make it harder to be detected by radar and other means than conventional aircraft by employing a combination of features to reduce visibility in the visual, audio, infrared and radio frequency (RF) spectrum. Well known examples include the United States' F-117 Nighthawk (1980s-2008), the B-2 Spirit Stealth Bomber, and the F-22 Raptor. While no aircraft is totally invisible to radar, stealth aircraft limit current conventional radar's abilities to detec ....etc

ABSTRACT

Electromagnetic bombs are Weapons of Electrical Mass Destruction with applications across a broad spectrum of targets, spanning both the strategic and tactical. As such their use offers a very high payoff in attacking the fundamental information processing and communication facilities of a target system. The massed application of these weapons will produce substantial paralysis in any target system, thus providing a decisive advantage in the conduct of Electronic Combat, Offensive Counter Air and Strategic Air Att ....etc

Variable sweep wings
ABSTRACT
VARIABLE-SWEEP WING
A variable-sweep wing is a wing configuration that allows to alter planform for various flight conditions. A variable-sweep wing can be moved during flight-usually between a swept-back position and a straight position. This allows it to take advantage of the aerodynamics of a swept wing at high speeds while avoiding the drawbacks of such a design at lower speeds. It is successful in this respect, but the added mass and complexity required counter the benefits and stand ....etc

ABSTRACT
This paper outlines some of the techniques being developed to provide affordable, reliable satellite communications suitable for a wide range of military aircraft, from agile platforms such as jets and helicopters to surveillance, tanker and transport aircraft. It also gives an overview of airborne SHF (Super High Frequency) and also EHF (Extremely High Frequency) satcom techniques. Although presently used UHF (Ultra High Frequency) satellite communication are relatively simple to install and comparatively inexpensive, suffer from ....etc

CHEMICAL ROCKET ENGINES
1. INTRODUCTION
Chemical rocket engines, like those on the space shuttle, work by burning two gases to create heat, which causes the gases to expand and exit the engine through a nozzle. In so doing they create the thrust that lifts the shuttle into orbit. Smaller chemical engines are used to change orbits or to keep satellites in a particular orbit. For getting to very distant parts of the solar system chemical engines have the drawback in that it takes an enormous amount of fuel to deliver the p ....etc

ABSTRACT

A scramjet (supersonic combustion ramjet) is reminiscent of a ramjet. The basic components of scramjet are inlet, diffuser, fuel injector, flame holder, igniter, and combustion chamber and exhaust nozzle. The basic principle of scramjet is same as that of any type of engine, intake, compression, combustion ....etc
