MAGNETIZES SYSTEM RAMJET TYPE

Ramjet Intakes

Intake design for supersonic engines, in common with other engineering design problems, is application dependent and the true challenges are in meeting performance targets over the required Mach and Reynolds number ranges while complying with the multitude of constraints imposed by the aircraft/missile and its mission. The fundamentals and limitations of efficient ram compression are well under...

Optical Measurements for Ramjet Engine Development

INTRODUCTION Advanced propulsion systems involve highly complex combustion flow processes. Extensive and accurate flowfield measurements can help to guide and support engine development. For example, in the hypersonic dual-combustor ramjet, the subsonic combustion chamber operating at fuel-rich conditions generates a complex multiphase combustion flow comprising liquid fuel droplets, soot parti...

Unified Analysis of Internal Flowfield in an Integrated Rocket Ramjet Engine. I: Transition from Rocket Booster to Ramjet Sustainer

A comprehensive numerical analysis was conducted to study the internal flow development in an integrated rocket-ramjet (IRR) propulsion system. The study consists of two parts: transition from the rocket booster to the ramjet sustainer and combustion dynamics during ramjet operation. The physical model of concern includes the entire IRR flow path, extending from the leading edge of the inlet ce...
