Inlet unstart prediction and warning are strictly crucial to the operation of hypersonic engines, especially for combined cycle engines where implementation across a wide speed range poses significant challenges. This paper proposes a realization method that involves constructing the conditions of critical backpressure ratios for the inlet unstart and ...

Dynamic Testing of a Hybrid-Propellant Water-Breathing Ram Rocket in Underwater Cruise Conditions
High-speed submerged marine vehicles, such as torpedoes, traveling at velocities of an order of 100 m/s and above, require powerful propulsion to overcome the tremendous hydrodynamic drag.

Analytical and Numerical Feasibility Analysis of a Contra-Rotary Ramjet Engine
A new idea for a contra-rotary ramjet engine is presented. To define the theoretical limits of the non-typical, contra-rotary ramjet engine configuration, its analytical model was developed. The results obtained from that model and the analytical results

Numerical Investigation on the Effect of Fuel‐Rich Degree in the RBCC Engine under the Ejector Mode
The ejector mode of the Rocket‐Based Combined‐Cycle (RBCC) engine is characterized by high fuel consumption. This study is aimed at investigating the influence of the rocket fuel‐rich degree on the RBCC engine’s performance under the ejector mode combined with simultaneous mixing and combustion (SMC).

Design of a Ramjet-Assisted Shell with Front Intake
Artillery shells are usually large-caliber projectiles fired by artillery guns. Present long-range artillery shells use techniques such as the base bleed system to reduce the drag coefficient of the shell, but could only increase the range of the shell ...
