Performance Studies of Pulse Detonation Engine Ejectors

Journal of Propulsion and Power, 2008
An experimental study on the performance of pulse detonation engine ejectors was performed. Time-averaged thrust augmentation produced by straight and diverging pulse detonation engine ejectors was measured using a damped thrust stand. The ejector length-to-diameter ratio was varied from 1.25 to 5.62 by changing the length of the ejector and ...

Detonation Performance of Ten Forms of 5,5′-Dinitro-2H,2H′-3,3′-bi-1,2,4-triazole (DNBT)

Crystal Growth & Design, 2018
Hydrate formation is a common mechanism by which the energetic performance of explosives can be degraded; the reason for this performance reduction has been difficult to tie to any physical parameter because typically only one solvate of a given ...

Performance Study on Detonation-driven Expansion Tube

16th AIAA/DLR/DGLR International Space Planes and Hypersonic Systems and Technologies Conference, 2009
In this paper, the development of a detonation-driven high enthalpy expansion tube is introduced and its performance study is reported. The facility consists of a forward detonation cavity driver, a shock tube and an expansion section. The detonation driver was specially designed to provide the facility with uniform driving flows. In performance tests,

USING SCHLIEREN VISUALIZATION TO TRACK DETONATOR PERFORMANCE

AIP Conference Proceedings, 2008
Several experiments will be presented that are part of a phased plan to understand the evolution of detonation in a detonator from initiation shock through run to detonation, to full detonation, to transition, to booster and booster detonation. High‐speed multiframe schlieren imagery has been used to study several explosive initiation events, such as ...

Propulsive Performance of Airbreathing Pulse Detonation Engines

Journal of Propulsion and Power, 2006
The propulsive performance of airbreathing pulse detonation engines at selected flight conditions is evaluated by means of a combined analytical/numerical analysis. The work treats the conservation equations in axisymmetric coordinates and takes into account finite-rate chemistry and variable thermophysical properties for a stoichiometric hydrogen/air ...
