Propulsion Systems for Hypersonic Flight

Plasma Telemetry in Hypersonic Flight

Problems associated with telemetry blackout caused by the plasma sheath surrounding a hypersonic vehicle are addressed. In particular, the critical nature of overcoming this limitation for test and evaluation purposes is detailed. Since the telemetry blackout causes great concern for atmospheric cruise vehicles, ballistic missiles, and reentry vehicles, there have been many proposed approaches ...

Towards High Efficiency Hypersonic Flight – Hypersonic Bi-Directional Flying Wing

This paper examines the use of a hypersonic bi-directional flying wing concept for use in a high efficiency hypersonic system. The bi-directional flying wing concept consists of a symmetric planform which enables flight to occur at two different geometric configurations. The subsonic configuration would have a high aspect ratio and a low sweep. The aircraft would then rotate 90 degrees and ente...

Simulation Modeling and Analysis of In-Flight Service Operations for Commercial Passenger Flights

Nowadays, in-flight comfort has become an essential characteristic to survive in domestic airline businesses. Air hostesses’ quality of service and response time to customer demand plays a vital role in enhancing quality of the flight experience and passenger satisfaction. However, additional requirements on air hostess expose them to fatigue which could eventually result in job dissatisfac...

CFD Validation for Hypersonic Flight: Real Gas Flows

The aerodynamics of future hypersonic air-breathing vehicles will be greatly affected by high-enthalpy or “real gas” effects. It is the purpose of a recent NATO Research and Technology Organization study to assess the readiness of computational fluid dynamics to simulate high-enthalpy flows. This paper summarizes the results of this effort through the discussion of four test cases: a transverse...
