Condensation of water vapour on heterogeneous nuclei in a shock tube

Aerospace in the next century

Some of the contributions of aerospace to civilization in its recent past, immediate present, and unfolding future are examined. Within the brief period of the last Century man has moved swiftly from his earth-bound cradle into the vastness of space to spread his first roots in the surface of his elosest heavenly refuge, the moon. The full...

Appraisal of UTIAS implosion-driven hypervelocity launchers and shock tubes

A critical appraisal is made of the design, research, development, and operation of the navel UTIAS Implosion-Driven Eypervelocity Launchers and Shock Tubes. Explosively-driven (PbN6-1ead azide, PETN-pentaerythritetetranitrate) implosions in detonating stoichlometric hydrogen-oxygen mixtures have been successfully developed as drivers for...

Shock and combustion-wave dynamics in an implosion-driven hypervelocity launcher

In order to solve many existing problems in planetary entry it is necessary to have facilities that are capable of launching undamaged projectiles at hypervelocities in excess of 50,000 ft/sec. (Ref. 1). Unfortunately, conventional light-gas guns appear to have reached a velocity plateau of about 30, 000 ft/ sec or less for launching integral...
