Arcas (rocket)
Encyclopedia
Arcas — also designated ARCAS — was the designation of an American
sounding rocket
, which was launched between July 31, 1959 and August 9, 1991 at least 421 times. The Arcas has a maximum flight altitude of 52 kilometers, a takeoff thrust of 1.5 kN, a takeoff weight of 34 kilograms, and a diameter of 11 centimeters. The Arcas was 2.30 m long and had a fin span of 0.33 m.
fed launch tube, Super Arcas was capable of reaching altitudes as high as 100 km. There were many time based weather experiments launched on this rocket due to the ability of the launch tube to be rapidly turned around for another launch. One of those experiments launched one rocket per hour for 24 hours straight in Antarctica.
, which was a 2 stage rocket; one Arcas stage and one booster.

Sounding rocket
A sounding rocket, sometimes called a research rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The origin of the term comes from nautical vocabulary, where to sound is to throw a weighted line from a ship into...

Super Arcas
A variant of the Arcas, Super Arcas, was used extensively around the world from a wide variety of platforms on land and at sea. With a boost from a gas generatorGas generator
A gas generator usually refers to a device, often similar to a solid rocket or a liquid rocket that burns to produce large volumes of relatively cool gas, instead of maximizing the temperature and specific impulse. The low temperature allows the gas to be put to use more easily in many...

Boosted Arcas
Another variation of Arcas was called the Boosted ArcasBoosted Arcas
Boosted Arcas is the designation of an American sounding rocket. The Boosted Arcas consists of a first stage of the type ARC booster or of the type MARC 42A1. The maximum altitude of the Boosted Arcas amounts to 50 km, the takeoff thrust 1,00 kN, the diameter 0,11 m and the length 3,40 m. The...

Arcas use with DMQ-6 telemetry
When used for radar calibration in the 1960s, the Arcas rocket configuration consisted of a closed breech launcher, a sounding rocket, and two payload configurations, one a parachute recovery system with a DMQ-6 telemetry transmitter compatible with standard meteorological ground station receiving equipment, the other a one meter metalized balloon for radar calibration. The Arcas characteristics for this type operation were:DMQ-6

- Maximum altitude: 210,000 feet
- Time to maximum altitude: 128 seconds
Balloon
- Nominal payload: 7 pounds
- Maximum altitude: 300,000 feet
- Time to maximum altitude: 134 seconds
Rocket:
- Altitude at burnout: 47,300 feet
- Launch velocity: 150/ft/sec.
- Total rocket weight: 77 pounds
- Outside dimension of tail: 4.45 inches
Transmitter:
- Robin balloon cross section
- DMQ-6 transmitter cross section
