Rocket was equipped with equaliser to prevent liquid-oxygen tank pressure from exceeding gasoline tank pressure, pendulum stabiliser, and 10-ft parachute; flame small and white; duration 12 sec; altitude about 1000 ft; then tilted to a horizontal powered flight at speed of over 700 mph; landed 11,000 ft from tower. Pendulum stabiliser as was expected gave an indication of operating the vanes for the first few hundred feet, but not thereafter.
Rocket had improved gyro stabilisation; length 14 ft 9 3/4 in.; empty weight 78 1/2 lb; altitude 4800 ft; average speed 550 mph; corrected its flight perfectly several times, for several hundred feet; horizontal distance, 13,000 ft; total time of flight, 20 sec.
Rocket had new gasoline orifices; duration of lift 12 sec; altitude about 4000 ft; speed high -- shot a wave of dirt, resembling a water wave, before it on landing. This completed Goddard's test of the A series of rockets. They had included 10 proving-stand tests and 14 flight test attempts, of which 7 resulted in flights. Average interval between tests was 28 days
Rocket equipped with a cluster of four combustion chambers, each 5.75 in. in diameter; length 13 ft 6.5 in.; altitude about 200 ft; fell near tower. The L series included four proving-stand tests and three flight test attempts, of which all were successful. Average interval between tests 25 days
Rocket was equipped with streamline retractable air vanes and wire-wound pressure storage tank; length 17 ft 8 in.; diameter 9 in.; altitude 3250 ft; duration 29.5 sec; much-improved stabilisation. Final results of Section B of L Series, from November 1936-May 1937, showed two proving-stand tests, and six flight test attempts, all of which resulted in flights. Average interval between tests 22 days
Rocket was equipped with movable-tailpiece or gimbal steering, with wire-wound tanks and barograph; length 18 ft 5.5 in.; diameter 9 in.; weight empty 95 lb 5 oz; loaded 162 lb 5 oz; 39 lb liquid oxygen, 28 lb gasoline; altitude 2055 ft; duration 28 sec; parachute opened near ground, checked speed; coasted one-eighth of ascent; landed 1000 ft from tower.
Rocket reached altitude 4920 ft as determined from telescope; from NAA barograph, 3294 ft, but altitude appeared greater visually and by telescope; corrected well, parachute opened at maximum point of ascent. This completed Section C of the L series, conducted from July 1937-August 1938. It had included seven proving-stand tests and 8 flight test attempts, all of which resulted in flights. Average interval between tests 25 days. For the entire L Series, from May 1936-August 1938, there were 13 proving-stand tests 13 and 17 flight test attempts, all of which were successful. Average interval between tests was 22-25 days
