HYDRAULICS IN MISSILES Nowadays‚ the electro-hydraulic actuator plays an important role in some modern tactical missiles. High power‚ great robustness and high tracking precision are the most significant demands for the missile actuator. Therefore an advanced method of active disturbance rejection control (ADRC) is presented aiming at the dynamics of the system are highly nonlinear and have large extent of model uncertainties‚ such as tremendous changes in load. Firstly‚ a novel ADRC controller

Landing Gear System Introduction to Landing Gear System: Landing gear system is the most important system in the aircraft which works with the hydraulic system and without which an aircraft cannot land on the runway. The landing gear consists of a nose gear‚ left and right landing gears under the wing. The main role of landing gear system is the energy absorption during landing‚ braking and taxi control. The components of the system are as follows: * Strut * Shock Absorber * Extraction/retraction

wheels. In the present day automobiles‚ power steering assist has become a standard feature. A hydraulic power steering uses hydraulic pressure supplied by an engine-driven pump. Power steering amplifies and supplements the driver-applied torque at the steering wheel so that steering effort is reduced. The recent introduction of electric power steering in production vehicles eliminates the need for the hydraulic pump. Electric power steering is more efficient than conventional power steering‚ since the
