Optimization of Hypersonic Airbreathing Propulsion Systems through Mixed Analysis Methods
Accurate flow path modeling of scramjet engines is a key step in the development of an airframe integrated engine for hypersonic vehicles. A scramjet system model architecture is proposed and implemented using three different engine components: the isolator, combustor, and nozzle. For each …

Experimental Evaluation of Innovative Thermal Energy Storage Options for a Hypersonic Non-Airbreathing Vehicle's Internal Loads
Managing the thermal loads inside a non-airbreathing hypersonic vehicle is particularly difficult. The heat generated by the power electronics, avionics, etc. must be removed so that the components do not exceed their maximum temperatures. These vehicles cannot dump the waste heat into fuel or ram …

Evaluation of Various Energy Storage Options for the Internal Thermal Loads of a Non-Airbreathing Hypersonic Vehicle
Energy storage within hypersonic aircraft is becoming increasingly important with the development of more sophisticated electronic components and is an integral piece of expanding their overall capabilities. Hypersonics not only produce large external thermal loads, but also an abundance of …

Development of an aerodynamic/RCS framework for the preliminary design of a hypersonic aircraft
The design of hypersonic airbreathing aircraft pushes the envelope of current state-ofthe-art aerospace propulsion and materials technology. Therefore, these aircraft are highly integrated to produce adequate thrust, reduce drag, and limit surface heating. Consequently, every aircraft component …

Creation of a Trimmed Powered Aerodynamic Database for a Generic Hypersonic Vehicle
… inviscid trimmed powered database for a generic airbreathing hypersonic vehicle. The database was created using the cartesian flow solver Cart3D. Propulsion effects were coupled to the airframe and inlet by using conditions at the inlet of the combustor to determine conditions at the exit of the …

Particle size and biotic composition on Western Cape shores, including first description of the unique fauna of pebble and cobble beaches
… in the form of drift kelp, although, as some airbreathing species were found in the low shore, it is presumed some such species migrated well into the intertidal at low tide, presumably retreating back above the high-water mark at high tide.

A combined cycle approach to dual-mode scramjet design and analysis
… ramjet (scramjet) engine. This hypersonic airbreathing powerplant, which is fundamentally comprised of a high-speed flowpath with no moving parts, belies its structural simplicity with the attendance of incredibly rich fluid and flame dynamics that govern its design and operation. While …

Investigation of Fuel Geometry and Solid Fuel Combustion for Solid Fuel Ramjets
Solid fuel ramjets (SFRJs) are a simple means of sustaining supersonic flight. The utilization of solid fuels eliminates the need for moving parts or liquid delivery systems, and the solid fuels are typically inert, resulting in minimal handling requirements compared to solid propellants. …
