MainDuties and Responsibilities:

The safety and suitability of a rocket motor for service requires proving through trials. These typically comprise firing trials to measure performance parameters such as thrust and pressure and environmental trials to assess such effects as ageing and transport.

These trials are carried out at our trials ranges where dedicated facilities exist for firing motors, climatic chambers for ageing and vibration rigs for transport.

Specialist trials are also often required. These comprise dynamic launch trials, structural trials, acceleration trials and insensitive munitions trials to name the most common. Some of these trials are carried out at our own trials ranges while others are carried out at third party ranges with our support.

All trials involve the use of bespoke instrumentation. The development and maintenance of this instrumentation forms an essential part of the responsibilities. This may range from routine high frequency pressure measurements to more advanced real time x-ray recording.
