Compact Electro-Hydraulic Actuator
- Summary
- Electro-hydraulic actuators (EHAs) are well known for their uses in many applications and offer several advantages such as compactness, versatility, and weight reductions. Current EHAs using gear pumps are easy to manufacture, but have lower efficiency than other EHAs. Prior EHA systems do not guarantee the actuator speed control or the load hold.
- Technology Benefits
- Saves weight and cost Actuator can be held in a fixed position regardless of the loadEasier maintenance for the system
- Technology Application
- Aircraft Cargo and vehicle doors Hatches and landing gears
