Distributed Parallel Processing and Dynamic Load Balancing Techniques for Multidisciplinary High Speed Aircraft Design
… here is configuration optimization of a high speed civil transport (HSCT), and the efficient parallelization of the embedded paradigm for reasonable design space identification. Two distributed dynamic load balancing techniques (random polling and global round robin with message …

Control-oriented Modeling of an Air-breathing Hypersonic Vehicle
Design and development of future high speed aircraft require the use of advanced modeling tools early on in the design phase to study and analyze complex aeroelastic, thermoelastic, and aerothermal interactions. This phase, commonly referred to as the conceptual design phase, involves using first …

A Study of the Thermal Properties of PETI-5/IM7
… that shows a great deal of potential in the high-speed aircraft and the aerospace industry. PETI-5 has been used for the High Speed Civil Transport (HSCT), a supersonic passenger aircraft in development at NASA. In this project, four staging samples, one fresh sample, one fully cured sample …

Longitudinal axis display requirements for high speed cruise
Altitude excursions particular to high speed aircraft are investigated in this thesis. An aerodynamic database of the XB-70 is created and a longitudinal linear model is constructed for a high speed cruise flight condition. An examination of the unpiloted aircraft dynamics revealed that the …

Response surface approximations for pitching moment including pitch-up in the multidisciplinary design optimization of a high-speed civil transport
… characteristic into the design optimization of a high-speed civil transport has been developed. Previously, the tendency of a high-speed aircraft to become uncontrollable (pitch-up) at high angles-of-attack during landing or takeoff for some wing shapes could not be included directly in the design …

The Solution of a Singular Integral Equation Arising From a Lifting Surface Theory for Rotating Blades
… a particular application, the motion of modern high speed aircraft propellers (Advanced Technology Propellers) is considered. The unknown propeller blade surface pressure distribution is approximated by a piecewise constant function and the integral equation is solved numerically by the method …

Synthesis and Characterization of Nitrile Containing Polysiloxanes and Their Corresponding Networks as Aircraft Sealant Materials
… at low temperatures, and thermal stability at higher temperatures. This wide service temperature range makes these materials a candidate class of materials for high performance adhesives and sealants, and in particular for applications on high speed aircraft. Polar polysiloxane networks were …

Thermal and Mechanical Response of Curved Composite Panels
… temperatures is required for anticipated future high speed aircraft applications. This study concentrates on the response of unstiffened, curved composite panels subjected to combinations of thermal and mechanical loading conditions. Mechanical loading is due to compressive end-shortening and …

Fluid-structure interaction of a cantilevered plate in supersonic separated flow
… (FSI) is one of ever-increasing importance as high-speed aircraft continue to reach higher Mach numbers. Research into high-speed FSI is especially critical with respect to control surfaces that may become compliant at these high Mach numbers. In collaboration with similar efforts at The Ohio …
