We have just become involved with assisting the Air Force to design new landing strips for new attack helicopters.
They want the landing strip to blend in with the surroundings so have opted for a reinforced grass or synthetic grass strip.
The problem arises from the way the helicopter makes contact with the ground. The approach speed is about 50 km/hour. The two back wheels point outwards in the air and then straighten on impact with the ground. Has anyone seen or used a product that can absorb/resist this movement or impact? Similiar landing strips for attack helicopters in the UK and USA show clear signs of deterioation of the surface due to this type of impact, the result is that dust particles are thrown or caught up in the rotors and cause damage to the helicopter.
Your advice would be appreciated.
