OTRAG (rocket)

The OTRAG rocket was a modular satellite-delivery rocket developed by the OTRAG company in the 1970s and 80s. The OTRAG rocket was to become a rocket built up from several mass-produced units, intended to carry satellites with a weight of 1-10 tons or more into orbit. Mass production meant that the vehicle was projected to have been 10x cheaper than conventional vehicles of similar capability.

Design

Various OTRAG rockets could be built up from the company's CRPUs (Common Rocket Propulsion Unit). A sounding rocket would bundle four or more CRPUs in parallel, topped with the payload. An orbital launcher would use dozens to hundreds of CRPUs, depending on payload mass. The launcher would then stage by dropping outer CRPUs, leaving the interior ones to continue with payload.

A CRPU was essentially a steel tube, 27 cm in diameter and 16 meters long, joined from a few shorter tubes. The CRPU was divided into three sections by aluminium bulkheads, with additional stiffening rings between bulkheads. Forward, the majority of the tube contained a mixture of nitric acid and nitrogen tetroxide oxidisers. Next was a section of kerosene fuel. This was commercial-grade kerosene, not the more expensive RP-1. Last was the engine section. A fuel line carried nitric acid around the kerosene, into the engine.

OTRAG

OTRAG (German: Orbital Transport und Raketen AG, or Orbital Transport and Rockets, Inc.), was a German company based in Stuttgart, which planned in the late 1970s and early 1980s to develop an alternative propulsion system for rockets. OTRAG was the first commercial developer and producer of space launch vehicles. The OTRAG Rocket claimed to present an inexpensive alternative to existing launch systems through mass-production of Common Rocket Propulsion Units (CRPU).

History

OTRAG was founded in 1975 by the German aerospace engineer Lutz Kayser. Its goal was to develop, produce, and operate a radically different, low cost, satellite launch vehicle.

The OTRAG rocket was intended to be an inexpensive alternative to the European rocket Ariane and the NASA space shuttle. Kayser and a private consortium of six hundred European investors financed the development and production of the OTRAG satellite launch vehicle. Dr. Kurt H. Debus served as Chairman of the Board of OTRAG after his retirement as director of NASA's Kennedy Space Center, and Dr. Wernher von Braun served as scientific adviser to Kayser.
