Analysis and compilation of missile aerodynamic data. Volume 2: Performance analysis

A general analysis is given of the flight dynamics of several surface-to-air and two air-to-air missile configurations. The analysis involves three phases: vertical climb, straight and level flight, and constant altitude turn. Wind tunnel aerodynamic data and full scale missile characteristics are used where available; unknown data are estimated. For the constant altitude turn phase, a three degree of freedom flight simulation is used. Important parameters considered in this analysis are the vehicle weight, Mach number, heading angle, thrust level, sideslip angle, g loading, and time to make the turn. The actual flight path during the turn is also determined. Results are presented in graphical form.

Fluid behavioral patterns found in subscale geysering study

Study provides a fundamental understanding of geysering mechanisms necessary for formulating theoretical analyses. An algebraic relationship between average heating rate, reservoir temperature, and geysering period was established and areas for future studies were identified.
