THE ARS-9 PRIMARY SURVEILLANCE RADAR HAS A DIGITAL OUTPUT INSTEAD OF THE ANALOG OUTPUT OF IT'S PREDECESSORS. THE COMPUTER AND DISPLAYS EQUIPMENT FOR NAVAL AIR TRAFFIC CONTROL COMPUTER NEEDS DIFFERENT DATA THAN THE ASR-9, NOW SUPPLIES. AN INTERFACE WILL BE DESIGNED THAT WILL TAKE THE OUTPUT OF THE ASR-9 EITHER FROM MODEM OR FIBER OPTICK LINK OR MICROWAVE LINK OR ON-SITE ATTACHMENT AND CONVERT FOR T ...

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 ...

A FEASIBILITY STUDY ON THE DEVELOPMENT OF A STOICHIOMETRIC DIESEL ENGINE IS PROPOSED USING THE THERMAL IGNITION COMBUSTION CHAMBER. THE ADIABATIC DIESEL ENGINE WITHOUT WATER OR AIR COOLING ALLOWS THE THERMAL IGNITION CHAMBER TO STORE HEAT DURING COMBUSTION AND RELEASE THE ENERGY FOR IGNITION IN THE FOLLOWING CYCLE. INJECTION OF FUEL ON TO 1800-2000 DEG. F WALL TEMPERATURE WILL PREPARE THE FUEL FOR ...

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 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 ...

High efficiency optical coupling between light sources and guided wave photonic devices is a key element in achieving compact and high performance integrated photonic systems. These systems will share a generic requirement of a source, a detector, and both active and passive guided wave components. A wide variety of materials exist in which to fabricate these guided wave components, but electro- ...

ASRI proposes to design and demonstrate a Phase Signature Antenna Drive Diagnostics System (PSADDS) for incipient fault detection and diagnostics of drive system bearing/gear train components. The PSADDS utilizes ASRI's innovative Phase Signature Analysis (PSA) techniques developed for the Space Shuttle Main Engine failure detection. conventional spectrum analysis has been a popular technique fo ...

A novel means to detect long wavelength infrared signals using parametric amplification is proposed. The new concept takes advantage of the large gains affordable with parametric amplifiers coupled with the superior uniformity and producibility characteristics of GaAs technologies. The detectors are expected to exhibit responsivity in excess of 12 A/W with detectivity greater than 10(13). Research ...

PERIODIC RESPONSE TIME TESTING HAS BEEN PERFORMED FOR THE PAST TWELVE YEARS ON THE SAFETY SYSTEM PRESSURE SENSORS IN MANY NUCLEAR POWER PLANTS. HOWEVER, THE RESULTS OF THESE TESTS ARE NOT RELIABLE FOR ASSESSMENT OF AGING EFFECTS. THEIS BECAUSE INADEQUATE METHODS AND PROCEDURES HAVE BEEN USED IN PERFORMING THE MAJORITY OF THE TESTS. THIS PROPOSAL OFFFERS AN EXPERIMENTAL RESEARCH PROJECT TO PROVIDE ...

The overall objective of this program will be to demonstrate the feasibility of a Dialectic Neural Network (DNN) architecture for use as an intelligent information processing engine for threat identification. To achieve this goal, several technical objectives have been identified that define, integrate and demonstrate the DNN architecture within the Army's Phoenix C41 software which will be used ...
