A low risk, low cost, classical design observation vehicle will be developed for gull launching. The observation vehicle concept is based on a light-weight loitering aircraft, packaged in a "shell" that will enable the aircraft to survive the large acceleration/deceler- ation loads associated with gun launch systems. The shell encasing the observation aircraft and avionics payload is designed to ...

The proposed effort focuses on the need for innovative, space realizable, self-contained actuators for precision positioning and vibration isolation. The proposed mechanism is a sealed linear actuator capable of high bandwidth (O-lkHz) control. A design feasibility study will be performed on the use of piezoelectrics in an innovative configuration to provide robust linear actuation for positioning ...

THE MISSION OF THIS PHASE I PROJECT IS COMPLETION OF A TRULY INNOVATIVE STUDY TO UPGRADE EXISTING PNS CODES FOR COMPUTING HIGHSPEED, THREE-DIMENSIONAL RE-ENTRY FLOWFIELDS. THE PLAN OF ACTION ENCOMPASSES A THOROUGH EXAMINATION OF THE RANGE OF ADMISSABLE CFD THEORIES, TO UNEQUIVACALLY COMPARE STRONG AND WEAK POINTS FOR APPLICATION TO THE REYNOLDS-AVERAGED NAVIER-STOKES EQUATIONS WITH DIFFERENTIAL EQ ...

The primary roadblock to the success of the high output Low Heat Rejection (LHR) diesel engine requiring little or no water cooling is the lack of effective liquid lubrication where target top ring reversal (TRR) temperatures between the cylinder liner and piston ring approach 1000 degrees F. Adiabatics, Inc. has developed a Thermo-sealed plasma sprayed Fe2O3 tribological coating which provides e ...

A meaningful computer simulation effort in the area of high-power machinery systems could have a major impact upon the cost of developing these systems. It is proposed, in this Phase 1, to develop modular, detailed and reduced-order digital computer simulations for an example high-power machinery system. Implementing these types of simulations using standard techniques may not be sufficiently inno ...

Two major objectives of the U.S. Army is to increase power density and reduce heat rejection. Reducing airflow requirements of the deisel engine will contribute toward both of these objectives. Reducing air-fuel ratio requirements is one of the major cost effective approaches available for significantly increasing power output and reducing heat rejection in today's power output diesel engine. Po ...

The technology for reliable real-time video communication between air cockpit to base, cockpit to cockpit and missiles to cockpit is of great importance in modern electronic warfare. Since the channel bandwidth for such a video-link is highly restricted due to limited transmission power and security require- ment, efficient video compression technique is essential. It is also desirable to incorp ...

A novel signal encoding/decoding method for laser ranging is proposed in response to solicitation AF96-186. Coherent burst ranging utilizes low cost diode lasers to achieve high precision ranging under ambient light conditions while operating at inherently eye-safe power levels. Proprietary signal processing methods to be developed will allow single-shot range resolution of approximately 1 mm at ...

THE STATE-EVENT CALCULUS (SECALC) IS A META-MODEL FOR SOFTWARE SYSTEM BEHAVIOR. STATES REFER TO SITUATIONS OF SOME DURATION WHILE EVENTS REFER TO SYSTEM ACTIONS PERFORMED BY SYSTEM ENTITIES IN RELATION TO OTHER SYSTEM ENTITIES AND EXTERNAL INPUTS. THE MAIN OBJECTIVES GUIDING THE INITIAL DEVELOPMENT OF SECALC WERE THAT: 1) IT BE COMPREHENSIBLE, 2) IT BE DERIVABLE FROM FUNCTIONAL SPECIFICATIONS (WIT ...

THIS PROJECT WILL RESULT IN THE RECOMMENDATION OF A TECHNIQUE TO BE USED FOR THE PURPOSE OF EVALUATING THE UTILITY OF STOL/STOVL TYPE AIRCRAFT IN VARIOUS OPERATIONAL SCENARIOS. THE STUDY EFFORT WILL INCLUDE A SURVEY OF PREVIOUS AND ONGOING STUDIES TO IDENTIFY POTENTIAL METHODOLOGIES, AN EVALUATION OF THOSE IDENTIFIED, AND RECOMMENDATION OF AN OPTIMUM TECHNIQUE. A SUGGESTED PHASE II STUDY PLAN WILL ...
