IN-FLIGHT STRUCTURAL RESPONSE OF THE MODEL A4D-1 AIRCRAFT TO A NUCLEAR EXPLOSION
Abstract
The objectives of this project were to: (1) measure thermal and blast gust response of the A4D-1 aircraft to nuclear explosion effects, (2) obtain data to improve the methods of predicting blast gust response of aircraft with wings of triangular planform, and (3) correlate experimental response data for the A4D-1 with analytical methods for use in determining its nuclear weapon delivery capability. The gust response results of the tests are presented as wing chord-wise and spanwise pressure distributions versus time, spanwise plots of wing section lift coefficient, average pressure, and center of pressure versus time, airplane center of gravity and tail acceleration versus time, airplane pitching motion versus time, wing shear, torque, and bending moment versus time, and tail load versus time. Other results of the tests are presented as irradiance and radiant exposure versus time, temperature in thin skin areas versus time, maximum temperature rise at each thermocouple location, peak overpressure, and time of shock arrival. The prediction methods presented in this report for the thermal effects gave fair agreement with the measured results for the radiant exposure and maximum temperature rise.
