Gyroscopic Couple Test Rig

Approx. component budget: Rs. 9,000 - 13,000

Objective

Measure the gyroscopic couple at different disc speeds and precession rates and compare it with the formula.

What you will build

A motorised disc in gimbal frames mounted on a turntable, with a spring balance or load cell to measure the gyroscopic reaction torque.

Results you can expect

• Measured vs theoretical gyroscopic couple
• Torque vs spin speed and precession rate
• Direction of the reaction

What you will learn

The gyroscopic effect and angular momentum, used in ships, aircraft, bikes and spacecraft.

Tools and notes

Tachometer, spring balance or load cell, Excel. Balance the disc properly and use a guard because the disc spins fast.

Resume points from this project

• Built and tested Gyroscopic Couple Test Rig; objective: measure the gyroscopic couple at different disc speeds and precession rates and compare it with the formula.
• Measured and analysed measured vs theoretical gyroscopic couple and torque vs spin speed and precession rate; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
