What type of actuator can PGMs use to assist with flight control?

Precision Guided Munitions (PGMs) often utilize both hydraulic and pneumatic actuators to assist with flight control. Hydraulic actuators are advantageous in various applications due to their ability to generate high force with a relatively small size, allowing for precise control of flight surfaces such as fins or canards. They operate by using pressurized fluid to move pistons, which can quickly adjust control surfaces, enhancing the maneuverability and stability of the munition during flight.

Pneumatic actuators, on the other hand, use compressed air to achieve similar control effects. They are generally lighter than hydraulic systems and can react quickly, making them suitable for applications where rapid adjustments are needed to maintain flight path stability.

By incorporating both types of actuators, PGMs can optimize their flight performance, allowing for more effective targeting and hit accuracy. This multi-faceted approach in utilizing both hydraulic and pneumatic actuators reflects advanced engineering principles in the design and operation of modern munitions systems.
