Abstract:

The Phase II tests were conducted to evaluate the flight envelope of the AH-1G with the SNS installed for significant changes in the structural loads, handling qualities and performance due to this modification. The effects of weapons firing on the SNS system were also evaluated. The structural loads, handling qualities and performance of the AH-1G were not significantly changed by the SNS installation. The published AH-1G flight envelope is satisfactory for the SNS modified aircraft with one exception due to the aircrafts reactions following sudden engine failure, the engine torque should be limited to less than 35 pounds per square inch, indicated, for all dives to airspeeds greater than 150 KCAS. Four deficiencies require correction before further testing in instrument flight conditions or in a combat environment.
