An innovative approach is proposed for the development of a low cost Air Turbo Rocket (ATR) propulsion system by using Off-the-Shelf (OTS) component technology. The proposed ATR propulsion system will be capable of delivering up to 500 lbf boost thrust and 265 lbf of fully throttlable sustained thrust with a 10-1 turndown ratio. All propulsion module integration requirements will be focused toward ...

In recent years, major advances have been made in nearly all areas of microelectronics development, including silicon technology, software development, and chip architecture. The one key area that has been more-or-less neglected however is packaging. The technology of packaging minature electronics such that they do not overheat is now the limiting factor in miniaturization. Experimental evaluatio ...

Surface pressure fluctuations due to turbulent flow over submerged bodies can cause vibration in the surface of the body which, in turn, may radiate noise. In order to predict the structural vibrations responsible for the acoustic radiation, the wavenumber/frequency spectrum of the pressure fluctuations must be known. Experimental data and analytical methods to predict surface pressure spectra cu ...

The proposed project will develop and adapt existing state-of-the-art computational tools for accurate prediction of ejection seat aerodynamic characteristics including rocket plume effects. The resultant CFD code will be based on the solution of the full Navier-Stokes equations with advanced turbulence and combustion modeling and will utilize a rocket plume model for capturing the shape and cha ...

High performance military aircraft operating in the hypersonic regime produce large heat loads that can only be managed with endothermic fuels. However, the current knowledge of endothermic chemistry in fuels and its effects over a range of aircraft flight conditions is extremely limited. The proposed Phase I study is aimed at the development of advanced finite rate models to characterize dehydr ...

Recent studies by CFD Research Corporation (CFDRC) have shown that pintel, rotating sleeve/iris and butterfly variable flow control concepts offer the most promise. During Phase I CFDRC will collaborate with Atlantic Research Corporation to synergize this program with an ongoing SBIR Phase II addressing advanced solid propellant chemistry for next generation air-breathing tactical missile thrust ...

An electrically driven high head rise centrifugal pump is proposed. Ongoing component technology development indicates this system will be required to meet next generation expendable Air-Turbo-Ramjet (ATR), Liquid Fuel RamJet (LFRJ) and turboJet missile propulsion engine requirements. During Phae I CFDRC will collaborate with Northern Research Engineering to: 1. design and fabricate a prototype ...

A three dimensional numerical simulator of nearshore waves is proposed. The simulator will assist military commanders in the planning of naval operations, including amphibious assaults. The transient, non-linear wave patterns in shallow waters are to be modelled using a Navier Stokes Computational Fluid Dynamics Code (CFD) coupled with an advanced volume of Fluid algorithm for tracking free surf ...

Significant progress has been made in recent years (through DARPA and industry initiatives) in developing real-time, on-line, model-based control systems to improve the productivity and flexibility of the US semiconductor industry. However, none of these initiatives have addressed the design of sensing systems which are crucial to the operation and efficiency of feedback control systems. The Pha ...

Mistakes made by programmers in the use of pointer variables and dynamic memory allocation is a significant cource of software errors. The development of a suite of tools to aid in the detection of these errors is addressed. These tools will operate both statically and dynamically in order to provide as wide a range of services as possible. The static tool will guarantee that certain pointer ba ...
