Gruzomaket

 2003-055A


978 kg dummy Kondor-E satellite on Strela test launch. Refurbished UR-100NU. NPO-M (Mashinostroenie). The satellite is a box

KGCh-2 payload section; rocket is 29.2l 2.5d 100t (Strela can also have KGCh-1 normal warhead fairing). Third stage is APB-OIA: agregatno-priborniy blok, equipment-service stage, with extra 2.4m dia 0.8m long otsek ismeritel'noy apparaturi, instrumentation module. The Strela rocket has the designation 14A036 and the APB is 14S425.

Mark Wade's site suggested an APB mass of 1100 kg full 725 kg empty with an Isp of 200s. With a 1000 kg payload this gives a delta-V of 1961 ln ( 2100 / 1725 ) = 386 m/s implying a preburn orbit of around -770 x 460 km. A plausible range given uncertainties in mass and Isp is 350-450 m/s, giving (-950 to -650) x 460 km.

The Strela user manual gives details of an ascent to a 1000 km orbit; the stage 2 sep, pre-APB orbit is then -600 x 1000 km. The fairing jettison at 114 km is to a -5485 x 190 km orbit; the stage 1 seps to -5740 x 165 km at 70 km.

The RKN 14A036 Strela used the 15S300 booster, the 14S425 APB, and the payload was KGCh 14S135, consisting of the 14S620 OIA, the 14S134 fairing, and the mass model GVM30201-14S135.
