Enclosure enhancement of flight performance

Flight Performance of the HEATRigidity

The HEAT (High Energy Antimatter Telescope) instrument was successfully own by high altitude balloon in May 1994. HEAT combines a new magnet spectrometer, comprised of a two-coil superconducting magnet and precision drift tube hodoscope, with a transition radiation detector and electromagnetic shower counter for particle identiication. Flight data are presented which demonstrate that the spectr...

Enhancement of Robust Tracking Performance via Switching Supervisory Adaptive Control

When the process is highly uncertain, even linear minimum phase systems must sacrifice desirable feedback control benefits to avoid an excessive ‘cost of feedback’, while preserving the robust stability. In this paper, the problem of supervisory based switching Quantitative Feedback Theory (QFT) control is proposed for the control of highly uncertain plants. According to this strategy, the unce...

Enhancement of composite performance by hollow polyester fibers

Stress Analysis of Flight Vehicles under Flight Conditions

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

Simulation of Mhd Mixed Convection Heat Transfer Enhancement in a Double Lid-driven Obstructed Enclosure

The present numerical study is conducted to investigate MHD mixed convection flow and heat transfer characteristics in a double-lid driven cavity with a heatgenerating solid square block. The cavity horizontal walls are adiabatic while both the vertical lids are maintained at a uniform temperature Tc and velocity V0. The present study simulates a reasonable system such as air-cooled electronic ...
