Essential Interview Questions For Gyroscopic Instrument Tester
1. What are the key components of a gyroscopic instrument?
- Rotor or spinning mass
- Gimbal suspension
- Sensing element
- Case and mounting structure
2. Describe the operation of a rate integrating gyroscope.
Precession
- When a force is applied to a spinning rotor, it experiences a torque that causes it to precess around an axis perpendicular to both the force and the rotor’s spin axis.
Integration
- The precession rate is proportional to the magnitude of the applied force, and the angle of precession is proportional to the time integral of the force.
Measurement
- The angle of precession is measured by the sensing element, providing information about the angular velocity or rate.
3. What are the different types of gyroscopic instruments used for?
- Inertial Navigation Systems (INS): Navigation and guidance in aircraft, ships, and submarines.
- Stabilization and Control Systems: Stabilization of platforms, cameras, and vehicle systems.
- Measurement and Calibration: Measurement of angular velocity, position, and orientation.
- Medical Applications: Tracking of body movements in rehabilitation and medical imaging.
4. How do you calibrate a gyroscopic instrument?
- Zero-rate calibration: Testing the instrument in a static or known angular rate environment to adjust for any offsets.
- Rate-sensitive calibration: Applying known angular rates to the instrument and comparing the measured rate to the reference rate.
- Alignment calibration: Verifying and adjusting the alignment between the gyroscope’s axes and a known reference frame.
5. What factors can affect the accuracy and performance of a gyroscopic instrument?
- Temperature: Thermal expansion and material properties can impact stability.
- Vibration: External vibrations can introduce noise and errors.
- Shock: Sudden impacts can damage or misalign the instrument.
- Magnetic Interference: Magnetic fields can affect the behavior of the rotor.
- Age and Wear: Fatigue and wear over time can degrade accuracy.
6. Describe the different test methods used to evaluate gyroscopic instruments.
- Rate Table Testing: Using a controlled rate table to apply known angular rates.
- Turn Table Testing: Rotating the instrument on a turn table to evaluate alignment, stability, and drift.
- Vibration Testing: Exposing the instrument to vibrations to assess its resistance to external disturbances.
- Temperature Testing: Testing the instrument’s performance at different temperatures to determine its thermal stability.
7. What are the safety precautions that should be taken when working with gyroscopic instruments?
- Secure mounting: Ensure the instrument is securely mounted and not subject to excessive forces.
- Avoid magnetic interference: Keep the instrument away from strong magnetic fields.
- Handle with care: Avoid sudden impacts or vibrations that could damage the instrument.
- Use proper calibration procedures: Follow established procedures for calibration and maintenance to ensure accuracy and reliability.
8. Describe the different applications of gyroscopic instruments in aerospace and defense systems.
- Inertial Navigation: Providing position and orientation information for aircraft, spacecraft, and missiles.
- Fire Control: Stabilizing and targeting weapons systems.
- Stabilization and Control: Maintaining stability and attitude control of aircraft, satellites, and other vehicles.
- Missile Guidance: Guiding missiles and rockets to their targets.
9. What is the difference between a rate gyro and a rate integrating gyro?
- Rate gyro: Measures the instantaneous angular velocity.
- Rate integrating gyro: Measures the angular displacement over time by integrating the angular velocity.
10. Explain the concept of drift in gyroscopic instruments and how it can be compensated for.
- Drift: Gradual change in the output of the gyro over time, even without any external input.
- Compensation: Techniques to reduce the effects of drift include using temperature compensation, signal filtering, and Kalman filtering.
