1. INTRODUCTION
Rocket engines that work much like an automobile engine are being developed at NASAâ„¢s Marshall Space Flight Center in Huntsville, Ala. Pulse detonation rocket engines offer a lightweight, low-cost alternative for space transportation. Pulse detonation rocket engine technology is being developed for upper stages that boost satellites to higher orbits. The advanced propulsion technology could also be used for lunar and planetary Landers and excursion vehicles that require throttle ....etc

PULSE DETONATION ENGINE TECHNOLOGY: AN OVERVIEW


Introduction
Imagine aircraft crossing continents and oceans at higher speeds and efficiencies.
Imagine spacecraft launching with higher safety factors and lower costs. Imagine
military craft operating in many flight conditions with increased performance. This is the
potential for Pulse Detonation Engine (PDE) technology; it has the capability to
revolutionize the aviation industry.


Description of Pu ....etc

A pulse detonation engine is an unsteady propulsive device in which the combustion chamber is periodically filled with a reactive gas mixture, a detonation is initiated, the detonation propagates through the chamber, and the product gases are exhausted. The high pressures and resultant momentum flux out of the chamber generate thrust.

Quasi-steady thrust levels can be achieved by repeating this cycle at relatively high frequency and/or using more than one combustion chamber operating out of phase.A pulse ....etc
