A BETTER ELASTOMERIC MODIFIER WILL BE SEARCHED AND USED FOR BISMALEIMIDE (BMI) RESIN TO IMPROVE THE TOUGHNESS OF THE RESIN. THE GOAL IS GOOD ROOM TEMPERATURE TOUGHNESS WITH GOOD STRUCTURAL PERFORMANCE IN THE 350-450 DEG F RANGE. NEAT RESIN SPECIMENS AND LABORATORY SCALE GRAPHITE FIBER COMPOSITE SPECIMENS WILL BE MADE FOR TOUGHENING TESTS AND EVALUATIONS.

A COMMUNICATIONS SYSTEM THAT IS PROPOSED THAT ALLOWS AN OPERATIONAL USER TO DIRECTLY ASCERTAIN THE USEFULNESS OF THE SYSTEM, IN TERMS OF SPECIFIED REQUIREMENTS. THE METHOD HAS SEVERAL ADVANTAGES OVER PREVIOUS TEST METHODS, INCLUDING EASE AND COST OF ADMINISTRATION AND EASE OF RESULT ANALYSIS. IT ALSO RETAINS THE ADVANTAGES OF THE BEST TWO-WAY COMMUNICATIONS TESTS WHILE ALLEVIATING THE PROBLEMS ASS ...

For aircraft /store compatibility, a comprehensive software system requested by the Air Force for rapid assessment of flutter and ejection loads (RAFEL) poses challenging requirements. With ZAERO aeroelastic software as a base, ZONA can establish a RAFELsystem satisfying all AF's requirements. Specifically, ZONA will develop RAFEL in Phase I with: a) solution accuracy with flutter solution robustn ...

Active noise and vibration control (ANVC) has not lived up to its promise. Attempts in the 1930's had little success because of inability to control the phase in electronics and transducers. Digital processing appeared to offer a solution for dealingwith phase and arriving at algorithms of a complexity that could not be realized by analog systems. There are applications where ANVC has achieved ...

Current research initiataives, including DoD IHPTET and HyTech, DOE ATS, and commercial development, are agressively pursuing significant improvements in combustor performance Optimization typically results in operating regimes for which combustionstability is difficult to maintain. This proposed program continues the novel combustion control and optimization concepts with flexible dual-use appl ...

Conventional passive control systems are associated with large penalties at off-design conditions that are frequently encountered in a typical flight envelope. The proposed innovation will result in the development of an active control system with highperformance gains at all flight conditions. A compact, diffusing inlet incorporating active flow control will be developed for Unmanned Combat Air ...

This Phase II will develop a cost- and weight-effective means for achieving an improved low- and mid-frequency acoustic environment in payload fairings for rockets at lift-off. The solution to be developed will consist an active noise control system withan optimum selection of SmartFoam, distributed active vibration absorbers (DAVAs) and acoustic actuators.
