In Experimental Design Bureau “Torch” (included in the integrated structure of the State Corporation NPO Energomash “Roskosmos”) collected five hundredth anniversary of the account SPD-50M engine for spacecraft OneWeb. Low-orbit satellite constellation OneWeb designed to create a space communications system that provides high-speed Internet at any point of our planet.
Assign SPD-50M engines – orbit correction and satellite orientation. At 1.29 kg weight and 16 mN thrust life of this motor is more than 3000 hours and the number of inclusions – more than 11 000. Its use in the composition of small satellites allows to increase the proportion of the mass of target equipment and active lifetime in orbit, due which significantly increases the efficiency of the engine being in the open space.
SPD-50M motors are supplied for the project LEO group Oneweb. The first six OneWeb satellites went into space from the Baikonur space center in Guiana on a rocket “Soyuz-ST” February 28, 2019. From Baikonur February 7, 2020 34 apparatus were withdrawn on March 21 – the same number. For the first time the Eastern OneWeb launched in mid-December 2020 – while 36 vehicles were withdrawn. Then starts a new Russian cosmodrome on 25 March, 26 April, 28 May and 1 July 2021, from Baikonur – 22 August and 14 September 2021. October 14 was held the 11 th starting at OneWeb program. Hundreds of satellites equipped with EDO production engines “Torch”, to be launched in the next few years.
Director OKB “Torch” Gennady Abramenkov: “October 14 upper stage” Fregat “brought 36 satellite to target a circular orbit at an altitude of 450 kilometers. It is very gratifying to be aware of the fact that the further transition into a working orbit at 1,200 kilometers OneWeb satellites will carry it using SPD-50M engines “.
