Book excerpt: The purpose of this program was to investigate experimentally the performance characteristics of high-pressure recovery, high-performance, advanced nozzle concepts for supersonic chemical lasers. Tests were conducted at small-scale (1 by 3 inches) sizes using scanning mirrors and a high-spatial-resolution IR spectrometer to examine performance. A small water-cooled pitot probe was used to scan the flowfield at the cavity exit to measure potential pressure recovery. A large-scale version of one of the nozzle configurations was designed and fabricated during this program and tested at the Mesa facility by the Aerospace Corporation. The Mesa results provided size scaling data for projecting Laser Engineering Test Facilities (LETF) results to larger sizes. Screening tests were performed on an advanced nozzle concept which provides increased mixing rates, larger throat dimensions, and decreased fabrication time and cost. The results of the screening tests indicated that the nozzles performed as predicted.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes experimental and analytical efforts conducted to develop a new chemical laser nozzle concept, the tri-stream (or three-stream) chemical laser nozzle. This nozzle expands the cavity fuel and the fluorine atom (combustor effluent) flows through the same nozzle. The fluorine and cavity fuel streams are separated by a layer of diluent flow to inhibit intermixing and reaction of the fluorine atom and cavity fuel in the nozzle. These three streams (fluorine atom, diluent, and cavity fuel) form a basic unit, or element, of the device, and the number of elements per unit length of nozzle is the most important parameter affecting the achievable performance. Tri-stream nozzles were designed, fabricated, and tested in 2.5-inch-long by 0.4-inch-high nozzle exit configurations. Laser power tests of the tri-stream nozzles were conducted in a free-jet test facility capable of pumping to cavity pressures as low as 2.5 torr. The maximum specific power achieved with DF* lasing using all helium diluent was slightly in excess of 80 kJ/lb. The maximum DF* specific power achieved with N2 nozzle diluent was approximately 60 kJ/lb.

Chalfant and published by . This book was released on 1976 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation of fine-scale three-dimensional chemical laser (HF/DF) nozzles was carried out. Under Task I three fine-scale cold reaction nozzles having different aerodynamic features were designed. Under Task II the 1-in. x 8-in. cold reaction nozzle fabricated in Task I was tested. The three fine-scale cold reaction segments fabricated in Task I were tested in Task III. A 1-in. segment of the fine scale chain reaction nozzle was also tested in Task III. Under Task IV theoretical analyses were carried out on the vibrational population distribution in the chain reaction nozzle and on the effect of alternative reactants on the performance of the cold reaction nozzle. Under Task V additional extensive tests of the 1-in. x 8-in. cold reaction nozzle were carried out to obtain a better correlation of the performance of this nozzle. Under Tasks VI and VII variable geometry cavity and diffuser walls with and without boundary layer injection were designed, fabricated and assembled.
