Spectrum (rocket)

from Wikipedia, the free encyclopedia

The Spectrum is a launch vehicle under development by the Bavarian space company Isar Aerospace . It is intended for the launch of small satellites . A first flight has been announced for 2021.

Structure and data

A two-stage rocket is planned that can bring up to 1000 kg payload into low earth orbits and 700 kg into sun-synchronous orbits . It should be 27 m long and 2 m in diameter. Two different sized payload fairings are offered.

The first stage is to be powered by nine liquid thrusters called "Aquila" with a total of 675  kN of thrust. It should have engine-out capability , i.e. at least one engine can fail without endangering the mission goal. A vacuum version of the engine with 94 kN thrust and multiple ignition capability is planned for the second stage; The latter enables complex orbit maneuvers. The engines are supposed to burn hydrocarbons with liquid oxygen . According to older manufacturer information, they should work with the gas generator process .

Manufacturer

Isar Aerospace was founded in March 2018 by space engineers Daniel Metzler, Markus Brandl and Josef Peter Fleischmann. The company is based in Gilching near Munich . The founding members were previously active in the Scientific Working Group for Rocket Technology and Space Travel (WARR), a group of students at the Technical University of Munich , which had already developed its own propulsion systems and a suborbital rocket . Isar Aerospace is supported by the ESA start-up funding program .

The heating manufacturer Viessmann and the venture capitalist UVC Partners , a company of two former employees of the space company SpaceX, participated in an initial financing round in summer 2018 .

In April 2019 Isar Aerospace had around 20 employees.

Planned launches

The Ludwig Maximilian University of Munich announced in early 2019 on the development of a research satellite that 2026 Template: future / in 5 yearsshould start with the Spectrum. Norway and Sweden are being discussed as possible locations for the launch site .
