Rocket Engine Impulse

The Teaching Challenge

Dramatically capture and visualize impulse data from a rocket engine ‘launch’. This is certain to capture your students’ attention.

Force delivered by the rocket engine over time. Use the area under the curve tool to find the impulse (thrust). The final data spike is the delayed charge (which in flight would eject the parachute).

The PASCO Solution

Simple place an Estes™ or other model rocket engine into the Rocket Engine Test Bracket, which is attached to a Force Sensor. Ignite the engine and immediately see the force data graphed over time. The area under the curve is the impulse delivered.

Safety Note: Please follow all safety procedures for igniting the rocket engine, and of course eye protection should be required. Please refer to product manuals for more information.
