Goddard L-C

---

Goddard series L sec Rocket was equipped with movable-tailpiece steering, catapult launching; corrected well and strongly in flight.

Status: Retired 1938. First Launch: 1937-07-28. Last Launch: 1938-08-09. Number: 8 . Thrust: 2.12 kN (477 lbf). Gross mass: 78 kg (171 lb). Height: 5.64 m (18.50 ft). Diameter: 0.23 m (0.75 ft).

• Start of Goddard series L section C liquid rocket tests - . Nation: USA. Related Persons: Goddard.

  These would run through August 9, 1938 (L16-L30). Section C rockets included light tank construction, movable-tailpiece (i.e. gimbal) steering, catapult launching, and further development of liquid nitrogen tank pressure method. Lengths varied from 17 ft 4.25 in. to 18 ft 5.75 in.; diameter 9 in., weight empty varied from 80 to 1091b; loaded weight about 170 lb or more; lift of static tests varied from 228 lb to 477 lb; jet velocities from 3960 to 5340 ft/sec. These tests indicated extremely high temperatures for the jet: pebbles of the cement gas deflector were fused and thrown out, starting fires more than 50 ft from the tower.

• Flight of Goddard series L section C rocket - . Nation: USA. Related Persons: Goddard. Apogee: 0.0400 km (0.0249 mi). Rocket reached altitude 140 ft; veered to right, landed 500-600 ft from tower..

• Flight of Goddard series L section C rocket - . Nation: USA. Related Persons: Goddard. Apogee: 1.50 km (0.90 mi).

  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
