Russian Helicopters developed first Ka-62 prototype helicopter will be subjected to vibration frequency tests in mid-July.
Three prototypes of Ka-62 have been built by the Progress Arsenyev Aviation Company. According to the approved plan, the first helicopter will be subjected to vibration frequency tests in mid-July to verify the efficiency of new improvements. If the test results so require, additional improvements will be made in the body structures of the anti-torque rotor and the tail group of all three flight models of helicopters, the company said in a statement last Friday.
The second flight model of Ka-62 has been delivered to the test checks and electrical systems workshop. Its on-board system will be tested in a computer-simulated environment and recalibrated. The third flight model of this vehicle will be tested soon thereafter.
