Current steady-state CFD combustion codes cannot predict transient combustion phenomena such as lean blowout (LBO) and ignition in gas turbine combustors. In this SBIR, we propose to develop an innovative analytical capability so that the combustordesigner can address operability issues. The key to predicting LBO/ignition is the use of time-accurate Unsteady Reynolds Averaged Navier Stokes (URAN ...

Elimination of diverter valve sensitivity to core exhaust backpressure fluctuations will be critical to the success of future fluidic exhaust nozzle control technology enhancement programs. During Phase I extensive analysis of the pilot valve size,injection configuration and feed losses, as well as pulse format (frequency, pulse width, etc.) influences on main diverter valve operation, will be co ...

Idealized analysis has shown that, for the same propellant supply pressure, higher performance can be obtained in a constant-volume combustion device than the traditional constant pressure rocket. CFDRC proposes an effort consisting of multiple levels ofanalysis, followed by design and testing of a rocket engine prototype that will substantiate this claim. Recent relevant experience in advanced ...

The project objective is to develop an integrated, hierarchical, multi-resolution tool for comprehensive prototyping and evaluation of new propulsion systems together with the launch vehicle systems. The overall vehicle system and its adjuncts will betreated as a collection of interacting software components coupled by a computational environment. Full and reduced scale component modules will al ...

CFD Research Corp. proposes the development of an Advanced Multipurpose Pseudospark Switch (AMPS) e-beam source capable of efficiently generating high average/peak current, bright electron beams. The improvement in e-beam quality (over a classicalpseudospark) stems from the inductive preionization of the hollow cathode chamber, prior to main gap breakdown. The proposed device features similaritie ...

Infrared image generation for IR sensor development and testing are currently large workstations costing several hundreds of thousands of dollars. Performance and image resolution is the key limiting factors of using PC hardware for this task. Usingdistributed processing, and intelligent algorithms, along with the forthcoming advances in PC graphics hardware; the next generation of real-time image ...

Recent developments in the area of artificial neural networks have led to a totally new brand of machine intelligence that is capable of autonomously improvising and implementing cunning concepts and strategies. This revolutionary neural networktechnology, called the

This proposal is for the design and development of a challenging, adaptable, and extendible A/I system for use in state-of-the-art computer-based wargames. The development will result in a 3rd generation computer wargame based on modern air power conflictand the ability to apply the technology developed for this project in other wargames ranging from tactical ground-based warfare to naval conflic ...

Traditional stationkeeping thrusters for satellites are low-efficient, complex, monopropellant or bipropellant chemical thrusters. The complexity and stored propellant of the thrusters result in satellites with higher dry weights, decreased payloadcapabilities, and thus higher incurred costs.A significant opportunity exists in the area of satellite stationkeeping for innovative propulsion systems ...

Miltec Missiles & Space Company and their subcontractor Secotec, Inc. propose to develop an innovative low cost ejector / diffuser system for economically producing a high vacuum in a very large chamber for use at Holloman AFB High Speed Test Track. Theunique and challenging requirement here is that this pressure vessel total length will most likely be thousands of feet and must be removable. The ...
