AN INNOVATIVE AND COST-EFFECTIVE APPROACH IS PRESENTED FOR DEVELOPMENT OF EXPLOSIVE SAFETY (QUANTITY-DISTANCE) CRITERIA FOR SHALLOW TUNNELS. THE APPROACH PROPOSES TO FORMULATE AND VALIDATE THE SCALING LAWS FOR Q-D INCORPORATING PROPERTIES OF EXPLOSIVES, AS WELL AS THE PHYSICAL AND MECHANICAL CHARACTERISTICS OF ENGINEERING SYSTEMS, I.E. CONCRETE, STEEL REINFORCING ELEMENTS, ETC.; AND GEOLOGIC SYSTE ...

THE OBJECT OF THE RESEARCH IS TO PRODUCE AN INTERFEROGRAM REDUCTION SYSTEM WHICH WILL ALLOW THE COMPARISON AND INTEGRATION OF THREE DIMENSIONAL EXPERIMENTAL INTERFEROMETRIC DATA WITH THAT DERIVED FROM CFD CODES. INTERFEROMETRIC TECHNIQUES PROVIDE AN IMPORTANT SOURCE OF DATA IN AEROBALLISTIC RANGES; HOWEVER, THE AVAILABLE DATA REDUCTION AND INTERPRETATION METHODS ARE SEVERLY LIMITING IN TERMS OF TH ...

ELECTROMAGNETIC PULSES HAVING RISE AND FALL TIMES AS SHORT AS 10 PS AND PULSE DURATIONS FROM 100 PS TO 10 NS ARE USEFUL FOR AIR FORCE APPLICATIONS RANGING FROM IMPULSE RADAR TO ULTRAWIDEBAND (UWB) WEAPON SYSTEMS. IN ORDER TO DEVELOP THESE SYSTEMS AND EVALUATE THEIR EFFECTIVENESS, IT IS ESSENTIAL TO BE ABLE TO MEASURE SINGLE PULSES HAVING BANDWIDTHS UP 30 GHZ IN A NONPERTURBING MANNER. AT PRESENT T ...

Deacon Research has developed the theory behind a new concept for a tunable infrared laser source. Our approach will deliver tunable coherent radiation across the 1 to 10 micron range with high efficiency. Since it is based on solid state pumping, the device will be very compact and rugged, enabling a range of new applications. All of the compoenent technologies have been demonstrated separatly ei ...

A PROGRAM OF WORK LEADING TO AN ANALYTICAL COMPUTATIONAL FLUID DYNAMICS (CFD) CAPABILITY TO PREDICT THE DETAILED FLUID MECHANICS OF AN EJECTION SEAT DURING HIGH SPEED EJECTION IS DESCRIBED. THE METHOD WILL CONSIDER TRANSONIC FLOWS AT HIGH DYNAMIC PRESSURES INCLUDING EFFECTS OF SHOCK WAVES AND POSSIBLE TRANSIENTS IN THE STAGNATION ZONE. THE PROPOSED ANALYSIS PROCEDURE, USING EXISTING TECHNOLOGY, WI ...

THE ABILITY OF CREWMEMBERS TO OPERATE EFFECTIVELY AND SAFELY IS CONTIN UOUSLY BEING TESTED AS AEROSPACE VEHICLES ATTAIN FASTER SPEEDS, HIGHER ALTITUDES, AND HIGHER G ENVIRONMENTS. THE CREWMEMBERS' BREATHING APPARATUS OR MOLECULAR SIEVE OXYGEN GENERATING SYSTEM (MSOGS) IS OF PRIMARY IMPORTANCE. HOWEVER, NO SENSORS ARE AVAILABLE THAT CAN MEASURE OXYGEN CONCENTRATION AND FLOW RATE SAFELY, BETWEEN THE ...

THE PURPOSE OF PHASE I OF THIS PROPOSED PROJECT IS TO CONDUCT RESEARCH TO ESTABLISH THE FEASIBILITY OF DEVELOPING A 4D VELOCITY SENSOR FOR SUBSURFACE AND SURFACE VESSEL NAVIGATIONAL USE IN A WIDE RANGE OF OCEANOGRAPHIC APPLICATIONS. THE SENSOR WILL EMPLOY ACOUSTIC CORRELATION VELOCITY LOG (CVL) TECHNOLOGY TO DETERMINE THE TRUE "EARTH FRAME" VERTICAL AND HORIZONTAL COMPONENTS OF SENSOR VELOCITY AS ...
