Fig. 9. THE EARTH: THE SYSTEM WITH THRUSTERS - EDTS

A CSC of 16800 kg mass with electrodynamic tether system (EDTS). SBs are not displayed. The upper circular orbit (300 km altitude)-- 7730 m/s. Reduction of the CSC speed in the upper circular orbit in course of capturing of the first portion of cargo of 50 kg mass is 23 m/s. Reduction of the CSC speed in perigee of the elliptical orbit in course of capturing of the second portion of cargo of 50 kg mass is 23 m/s. The lower circular orbit (220 km altitude) -- 7777 m/s. Electric power of the membrane SB -- 2.5 MW FC electric power -- 1 MW. EDTS electric power -- 1 MW. FC charging efficiency -- 0.6 SB mass -- 1250 kg (0.5 kg/KW) FC mass -- 1000 kg (1 kg/KW) EDTS mass -- 5000 kg Cargoes' catcher mass -- 1000 kg. The rest equipment mass -- 8550 kg. Mass of the captured portion of cargo -- 50 kg. Length of the track of the cargo substance -- 8000 m. Time of track capturing -- 1 s. Acceleration of braking in course of cargo capturing -- 23 m/s2 (~2.3g) Number of operations on cargo capturing in points 1 and 2 for 1 year -- 8000. Mass of the captured cargo for 1 year -- 400 tons. Mass of the cargo used in correction ERE for 1 year -- 0.1-1 tons. Mass of the cargo accumulated in the orbit for 1 year -- 400 tons. The fleet of multiuse suborbital rockets for exploitation in course of 1 year -- 20-40 pieces (with 200-400 launches/rocket endurance).
