Book Description
This report describes the design, instrumentation and operation of two intermittent facilities for Gas Dynamic Laser research. Intermittent facilities have the attractive characteristics of very low cost, configuration flexibility, and ease of conducting tests with a large dynamic range of initial conditions. The kinetics of vibrational freezing in gas dynamic laser nozzles was studied. Small signal gain, static temperature, pressure and Mach number were measured downstream of the nozzle exit. Results for different mixtures, total temperatures, and area ratio changes are presented. Results of a research program to study the effects of contraction ratio, length, and wedge angle on the performance of a vane diffuser are presented. The effects of promoting early boundary layer transition are shown to be important in vane diffusers. A separate study was performed to determine the effects of impulsive starting vane diffusers compared with quasi-steady starting. The results conclusively show no change of start or unstart performance due to impulsive operation.

Chemical Laser Facility Study. Volume III. Cost Analysis
Author: W. A. Gaubatz
Publisher:
ISBN:
Category :
Languages : en
Pages : 33
Book Description
A summary of the site development and equipment costs for the development of the complete facility at Kirtland Air Force Base, Albuquerque, New Mexico, is presented and operational requirements are discussed. The funding requirements presented in this volume are divided into two categories of Site Development and Laser Test System. The Site Development items defined in Volume I comprise the Military Construction Program for the facility; the Laser Test System items, defined in Volume II, comprise the RDT and E funding required for the facility. This document is Volume III of a three-volume final report covering the overall study conducted for the Air Force Weapons Laboratory to define the total cost and to specify design criteria for a Chemical Laser Test Facility. The design criteria for the architectural and engineering design of the facility are presented in Volume I and the design requirements for the Laser Test System are presented in Volume II.
