Condition test run test, demonstrates the feasibility and reliability of its work, ensure that the progress of Project R&D.Its design philosophy can be it
His model is offered reference and is referred to；
4, position of the water injector of the present invention in pilot system is reasonable, can real simulation flying height rain bullet on
Water swallows mode, reliability with higher.
Encounter rainy when guided missile flight in the sky, rainwater can enter in punching engine and participate in burning, when ground experiment,
Water injector arrangement position need conscientiously to discuss, be placed on motor inlet or inlet mouth on engine influence difference,
Water injector is laid between rectifier and simulation air intake duct by the present invention, being capable of rainwater under real simulation flying height on bullet
Swallow mode, reliability with higher.Air mixing if water injector is placed on punching engine entrance, after water spray
Object can not be accomplished highly uniform, while when rainwater enters engine, can not be gasified totally, larger with real work difference.By
Be in cruise missile end in punching engine, when flight, after the air containing rain enters guided missile, through by it is very long into
Then air flue reaches punching engine, rainwater has been gasified totally at this time, and therefore, when ground experiment, water injector is placed on
Simulate inlet mouth, can more true simulated missile flight when working condition, guided missile under real simulation flying height
Rainwater swallow mode.
