Performance requirements for hydraulic steering gear

Performance requirements for hydraulic steering gear
The requirements for hydraulic servo mechanisms applied to aircraft and missiles are much stricter than those for general servo mechanisms, mainly in the following aspects:
(1) Within the required continuous working time, there is sufficient power output to meet the requirements of torque (or thrust) and speed (or speed).
(2) It has good dynamic performance and requires necessary stability and fast performance under high inertia loads. In aviation applications, speed with a certain stability margin is a key issue. The maneuverability of fighter jets and tactical missiles is high, and the response speed of the servo mechanism directly affects the quality of the control system and automatic control system.
(3) Not sensitive to external environmental influences (such as impact, vibration, acceleration overload, high and low temperatures, etc.), with a large load stiffness, and strong control ability for anti maneuvering states.

Advantages of hydraulic steering gear
The hydraulic servo control system is used to achieve the purpose of controlling the deflection angle of the rudder surface. The electro-hydraulic servo control has the characteristics of fast response speed, light weight, small size, and high load resistance rigidity. It is precisely because of the use of electro-hydraulic servo control in modern aircraft flight control systems that the flexibility and adaptability of the aircraft control system are improved, Ensuring the required stability and controllability (maneuverability) of the aircraft in all flight states is crucial for improving
The aerodynamic performance and layout of aircraft play an important role in ensuring the safety of rudder flutter. Hydraulic servo control device is one of the main devices in modern aircraft control systems and large and medium-sized missile control systems. It is almost a determining factor in the dynamic characteristics of the missile's flight control system.
