Rockets are tested at Radford (Va.) Ordnance Works in front of a grid which measures backward blast of propellent gases. Fixed rocket is fired against the wall at left.
Rocket is clamped to a concrete block to keep it stationary during firing. Gauges record the pressure exerted against the head of the rocket when the powder is ignited.
Result of firing is checked from a photographic film which records electrically what happens while powder burns. Pattern is measured for burning time and pressure.
