Cajun Dart


American sounding rocket. Single stage vehicle.

The Cajun-Dart chaff rocket was a two-stage dart type sounding rocket. The first stage of the Cajun-Dart was the Cajun Mod III rocket motor. The Cajun motor was 2.591 meters long and had a principal diameter of 0.165 meters. The motor, less flight hardware, weighed 77.566 kilograms with 53.752 kilograms of propellant. The nominal burning time was 2.8 seconds, with a total impulse of 11,453.4 kilogram-seconds yielded a burnout velocity of slightly over 1.524 kilometers per second at an altitude of 2.134 kilometers.

When the booster burned out, the aerodynamic differential drag caused the booster to separate from the Dart. After separation the Dart continued to coast to payload ejection. The Dart was 0.044 meters in diameter, and weighed 7.711 kilograms. The nose of the Dart was designed to have a hypersonic optimum shape to keep aerodynamic drag to a minimum. The aft end was boat-tailed, forming the interstaging surfaces, as well as reducing the base drag. The payload housed inside the Dart was 655.6 cubic cm of 5-mil aluminized Mylar foil chaff cut to S-Band length.

When the Dart had reached its apogee, the payload was ejected by the use of a 145-second pyrotechnic time delay housed in the Dart's tail and initiated at launch. At 145 seconds the time delay ignited the expulsion system which ejected the Dart nose cone and the chaff payload by forcing a piston the full length of the Dart. The chaff was then free to drift with the wind as it fell. The Cajun-Dart system was launched from a rail type launcher.

The Cajun-Dart igniter consisted of a tube containing two U. S. Flare 209 Squibs, 7.5 grams of ignition powder, and 90 grams of USF 2A granules. The two squibs were wired in parallel and were of the one amp, one watt type.

Associated Launch Sites
  • Wallops Island Small NASA launch site for sounding rocket launches and occasional Scout launches to orbit. Air launches are conducted from the Drop Zone Wallops Island, 37.00 N 72.0 W. With the last orbital launch in 1985 and the decline in sounding rocket launches, Wallops fell into near-disuse as a launch center. Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
  • Eglin This US Air Force proving ground and missile test range, based in Valparaiso, Florida and extending over a vast expanse of the Gulf of Mexico, was founded in 1935, In early 1946 the First Experimental Guided Missiles Group was activated at Eglin. The highly-instrumented Eglin Gulf Test Range supported flight tests of Bomarc, Matador, Quail, and Hound Dog cruise missiles. Both the military and NASA used Eglin to support launch of sounding rockets in support of their programs. Eglin was known to have been used for 441 launches from 1959 to 1980, reaching up to 686 kilometers altitude. The actual number of missile tests was many times greater. More...
