illic, litter AIRCRAFT ROCKET TESTS WHEN a newly-designed aircraft rocket has been thoroughly tested by ground firing, it is ready for experimental firing from aircraft. If it is a small round or a round of conventional design it is generally launched from an airplane in flight without further tests. If it is a round of radical design, however, preliminary tests may first be performed by firing from an airplane which is at rest on the ground or is supported in flight attitude by special cranes. If any damage is sustained by the aircraft in these tests, the rocket launchers on the aircraft may be modified before attempting to fire a round during actual flight. Experimental firing of rockets from combat airplanes has several purposes. The most important of these is the determination of ballistic data under various flight conditions approximating those encountered in combat. Rocket trajectories are affected by such variables as the speed and altitude of the airplane, launcher angle, type of launcher, type of round, and temperature. The California Institute of Technology has evolved formulas for computing sight-setting tables which take these variables into account. The computations for these tables are based on the results of experimental aircraft firing at the Test Station. 24
