Laser Initiated Ignition of Liquid Propellant.
Abstract
Central to the study of laser induced ignition of propellants is the provision of the igniting pulsed laser. Single pulses delivering in excess of 10 J energy were considered desirable. Because of the delay, the required laser which was to be obtained through BRL was not immediately available and some doubt has been expressed as to whether it would become available in the current financial year. Accordingly, an emergency plan based on attempting to revive our defunct 211A pulsed ruby laser was put into operation. This laser became non-operational some time ago, due to the leakage of cooling water through a small pin hole into the pumping flash lamp. Contrary to the manufacturers' specifications, replacement of the failed component did not cure the problem but caused the output to drop by 2 orders of magnitude to around 200mJ. Keywords: Great Britain.
