The overall abjective of this proposed project is the development of detailed definitions for the interfaces defined by the ABBET architecture. Signal models wil developed based upon the C/ATLAS set of signal nouns. A Test Foundation Framework (TFF) will be implemented to demonstrate the ability of test program or test program component transfer across multiple test platforms. This phase also w ...

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 ...

Proposed enhancement of the thermal control of rocket engine combustion chambers is achieved by implementing advanced high thermal conductivity, light weight polycapillary materials (APM) to provide improved transpiration cooling of the walls and/ordevelop efficient ablative chamber wall material. MER Corporation has developed the method of fabricating metal and/or ceramic APM characterized by ...

Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...

Affordable/low cost carbon-carbon (C-C) composites are enabling to a number of defense, aerospace and commercial applications. However, in addition to cost, their limitation is carbon gasification in oxidative environments above about 750¿F (=400¿C). An inhibited carbon matrix that reduces oxidation rate by a factor of 200 with up to double the strength of uninhibited composites which could be ...

We will develop a proof-of-concept system that implements an innovative methodology to diagnose and repair unknown satellite anomalies. Our system is based on a novel approach that integrates Case-Based Reasoning (CBR) with Utility Theory. The resulting system deals with unknown and missing information, and selects from a case base the plans or actions that will either fix the satellite or will ...

The firm proposes to conduct a program of research on real-time engine health monitoring (EHM) system for gas turbine engines. The proposed system is motivated by several factors: 1) effective monitoring improves engine performance and operability, 2) current engine monitoring field is fragmented and it needs standardization, 3) effective monioring requires advanced modeling and information pro ...

An innovative variable stiffness spar (VSS) approach is proposed for the enhancement of aircraft roll performance. F/A-18 pre-roll-modification aircraft (F/A-18 PRM) is selected as the baseline aircraft for its low torsional wing stiffness and available baseline data. The F/A-18 PRM, when integrated with VSS (F-18/VSS), requires only the outboard trailing-edge aileron for roll maneuver. The pre ...

A material which is stronger than conventional aluminum, less permeable to liquid hydrogen than polymer matrix composites (PMCs), less flammable that PMCs in the presence of liquid oxygen, and can be made into large, complex shapes without an autoclave, would have a significant advantage over current cryogenic tank materials. Touchstone Research Laboratory proposes its ...
