N/A

AN EFFICIENT COMPUTATIONAL METHOD IS PROPOSED FOR MODELING THE COMPLEX PHYSICAL PHENOMENA OCCURING IN HIGH ENERGY CONTINUOUS WAVE LASER FLOW FIELDS. THESE FLOWS TYPICALLY CONTAIN BOUNDARY LAYERS, MIXING LAYERS, WAKES, AND EMBEDDED SHOCK WAVES. IT IS DIFFICULT TO GENERATE A MESH APRIOR WHICH WILL RESOLVE ALL FEATURES OF THE FLOW. THEREFORE, AN ADAPTIVE GRID TECHNIQUE WILL BE USED AND COUPLED TO AN ...

THE DEVELOPMENT OF A REMOTE LONG TUBE INSPECTION SYSTEM IS PROPOSED. THE OBJECTIVES OF THIS RESEARCH AND DEVELOPMENT EFFORT ARE TO EVALUATE VARIOUS CONCEPTS CAPABLE OF INSPECTING THE TUBE SURFACE AND REMOVING FOREIGN OBJECTS AND TO SELECT THE MOST PROMISING TECHNIQUES FOR DEVELOPMENT INTO A REMOTE INSPECTION SYSTEM. THE OBJECTIVE OF PHASE I IS TO DEVELOP A CONCEPTUAL SYSTEM DESIGN. THIS PHASE WILL ...

COMPOSITE STRUCTURES IN SPACE MAY BE SUBJECT TO SOURCE OF THERMAL ENERGY, WHICH INCLUDES X-RAYS FROM NUCLEAR WEAPONS AND HIGH ENERGY LASER LIGHT. THIS PROPOSAL ADDRESSES THE NEED FOR ANALYSIS TOOLS TO PREDICT THE EFFECTS OF RAPID THERMAL PULSE LOADING ON AEROSPACE COMPOSITE MATERIALS. A MAJOR OBJECTIVE OF THIS PHASE I STUDY IS TO DETERMINE THE FEASIBILITY AND MAGNITUDE OF EFFORT TO DEIVER SUCH AN ...

A SYSTEMATIC INVESTIGATION OF THE IONIZED CLUSTER BEAM (ICB) DEPOSITION TECHNIQUE IS PROPOSED. THE ICB METHOD ALLOWS A BROAD RANGE OF CONTROL OVER THE SURFACE MOBILITY OF DEPOSITED ATOMS AND HAS BEEN APPLIED SUCCESSFULLY TO A VARIETY OF THIN FILM MATERIALS. HOWEVER, A NUMBER OF FACTORS HAVE HAMPERED U.S. RESEARCH IN THIS AREA, SO THAT THERE IS NOT NOW A SUFFICIENT BASE OF KNOWLEDGE OR EXPERIENCE T ...

N/A

THE NEED EXISTS FOR AN ADVANCEMENT IN EXPLOSIVE EXCAVATION METHODS TO IMPROVE THE EXISTING CYCLIC PROCESS. PHASE I OF THIS PROJECT WILL PROVE FEASIBILITY OF AN INNOVATIVE EXPLOSIVES EXCAVATION SYSTEM WHICH WILL COMBINE THE AUTOMATION OF TUNNEL BORING MACHINES WITH THE LOW ENERGY AND FLEXIBILITY OF EXPLOSIVES. THE SYSTEM WILL INCLUDE A CONTINUOUS, CONCURRENT CYCLE OF DRILLING LOADING, BLASTING AND ...

THE PURPOSE OF THIS STUDY IS TO INTEGRATE THE APPLICABLE FIELD, DEPOT AND OTHER AIR FORCE MAINTENANCE DATA INTO A SINGLE AND CONCISE MAINTENANCE HISTORY OR BASIC DATA PACKAGE. THIS PACKAGE OR HISTORY IS DESIGNED TO CONTAIN THE INFORMATION REQUIRED BY ALL OF THE USING DISCIPLINES, TO INCLUDE ALL OF THE CONTRIBUTING MAINTENANCE LEVELS (HARDWARE REPAIR, REMOVE AND REPLACE, CHECKED OK, ETC) AND, FINAL ...

N/A

STRUCTURAL LATCH MECHANISM CONCEPTS WILL BE DEVELOPED TO BE USED ON FUTURE FIGHTER AIRCRAFT FOR INTERFACING THE CREW ESCAPE CAPSULE WITH THE AIRFRAME. THE F-111 ESCAPE CAPSULE DESIGN WILL AID IN THE GENERATION AND VALIDATION OF PRELIMINARY DESIGN REQUIREMENTS. THREE PHILOSOPHIES WILL BE CONSIDERED IN DEVELOPING THE DESIGN CONCEPTS. ONE WILL MAXIMIZE THE LOAD DISTRIBUTION BETWEEN THE TWO STRUCTURES ...
