A sensitive thin film thermometer has been developed which can measure local transient surface temperatures without appreciably affecting flow of heat or fluid in the vicinity. By means of techniques used in microminiaturization, the thermometers can be deposited at close spacings. This note describes the manufacture of such instruments and discusses their sensitivity, frequency response and reliability.

Studies have been conducted on an Air Cushion Landing System for the Australian Jindivik target drone aircraft. Analyses are presented of the airflow and yaw thruster control systems, and the vehicle stability with a deployed recovery trunk is assessed. The vehicle touchdown and slideout on a recovery trunk are presented, and the design of an improved retention/release system is shown. (Author)
