Download or read book The Nol 3 Mw 3-phase A-c Arc Heater (mark Ii). written by R. E. Lee and published by . This book was released on 1965 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: An a-c arc heater developed for the NOL 3 MW research arc is described. This heater has three doughnut-shaped electrodes with internal coils to increase the magnetic field strength. The operation and performance of this design are discussed. Temperatures from 3500 to 4000 K with efficiencies from 15 to 23% were obtained at pressures from 10 to 15 atmospheres. Multiple arc streamers and the diffusion of the arc into the center of the chamber were observed. A high level of contamination of the effluent gas, an unsatisfactory magnetic design, and short component life make the design unsatisfactory. Methods of eliminating these problems are discussed.

Book Synopsis Arc Rotation in 4 Ring AC Arc Heater by : Richard L. Humphrey
Download or read book Arc Rotation in 4 Ring AC Arc Heater written by Richard L. Humphrey and published by . This book was released on 1968 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of arc column rotation in a 4 ring ac arc heater without an external magnetic field is presented. Arc column speed is found to depend upon arc current, arc heater pressure, amount and direction of air injection and electrode geometry. The methods used for the experiments and the evaluation of the filmed data are described and justified. Arc heater efficiency and stability has been improved as a result of this work. (Author).
Book Synopsis The NOL 3 Megawatt Research Arc by : Erhard M. Winkler
Download or read book The NOL 3 Megawatt Research Arc written by Erhard M. Winkler and published by . This book was released on 1964 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and initial performance of a 3 MW electric arc air heater are discussed. This arc will be used as a heat source in a true temperature wind tunnel designed, and currently under construction, for operation at Mach numbers between 3 and 12 at supply pressures of 5 to 150 atmospheres and total energy levels up to 5300 Btu/lb. The arc heater operates on 3-phase a.c. Its components, control systems and instrumentation are described in detail. The initial performance studies were carried out using a Mach number 3 nozzle with the flow expanding into the ambient atmosphere. These tests were carried out at supply pressures up to 45 atmospheres. The highest gas energy level obtained was 7700 Btu/lb. (Author).

Book excerpt: Two 4-electrode 3-phase arc heaters (designated Mark III and IV) are described. These heaters feature smaller internal volumes and electrode diameters than the previous heaters. The air temperatures and efficiencies produced by the Mark III arc heater are higher than those previously obtained. The Mark IV heater, now under construction, is designed to two-minute operation with a hypersonic wind tunnel.

Book Synopsis Gasdynamic Lasers: An Introduction by : John D. Jr. Anderson
Download or read book Gasdynamic Lasers: An Introduction written by John D. Jr. Anderson and published by Elsevier. This book was released on 2012-12-02 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gasdynamic Lasers: An Introduction is a 12-chapter introductory text to major development generations of gasdynamic lasers, focusing on their underlying physical and fundamental aspects. The opening chapters discuss the basic detailed physical phenomena that ultimately are responsible for producing gasdynamic laser action and the methods of calculating the performance of these devices. These topics are followed by a chapter on confirmation of the performance calculations through arc and shock tunnel experiments. The discussion then shifts to vibrational relaxation process behind normal shock waves in CO2-N2-He mixtures and assesses their population inversions occurring in the nonequilibrium flow. Other chapters explore the concepts of downstream mixing and optical cavity in gasdynamic lasers, as well as the laser beam extracted from these devices. A systematic study of aerodynamic windows that use supersonic flow across the aperture is presented in the concluding chapters, along with the phenomena associated with gasdynamic laser diffusers. This introductory text will be of great value to professional scientists and engineers, as well as to students and workers in the field who are interested in interdisciplinary applied science.

Book Synopsis Three-phase AC Arc Heater by : R. L. Phillips
Download or read book Three-phase AC Arc Heater written by R. L. Phillips and published by . This book was released on 1964 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental and theoretical investigations into the technology associated with three-phase AC arc heaters is presented and critically discussed. The behavior of the three-phase arc is extensively considered and it is shown that a previously reported analysis can adequately predict this behavior. The problems of designing arc heater components are discussed and in particular those associated with the pressure vessel. It is shown that the present, low pressure chamber extracts an unacceptable amount of energy from the arc heated gas resulting in a rather low unit efficiency. Finally, the benefits which might result from coupling a magnetogasdynamic accelerator to the arc heater for flight simulation are discussed and on the basis of perfect accelerator performance (no losses) it seems that significant increases in stagnation properties can be effected.
