Chinese orbital launch vehicle. The 522/HO was the 'all up' baseline configuration for the Long March New Generation Launch Vehicle series. It would use the 5.0 m core stage, topped by the 5.0 m upper stage, together with 2 x 2.25 m plus 2 x 3.35 m strap-on stages. It was announced in 2003 that it would be first to fly, with a launch before the Beijing Olympics in 2008. It would be used for launch of large communications satellites. Payload is estimated as 10-12 tonnes to geosynchronous transfer orbit.

Payload: 11,000 kg (24,000 lb) to a GTO.

The oxygen tank is pressurised using oxygen bled from the engine and helium is used to pressurise the kerosene tank. The engines can be throttled to 65% of rated thrust. Burn time shown assumes full thrust during engine burn.
  • Stage 2. 1 x CZ-NGLV-500. Gross Mass: 175,000 kg (385,000 lb). Empty Mass: 17,000 kg (37,000 lb). Thrust (vac): 1,399.990 kN (314,730 lbf). Isp: 432 sec. Burn time: 480 sec. Isp(sl): 333 sec.

From top to bottom the 5-m Chinese new generation launch vehicle consists of a 117.3 cubic meter liquid oxygen tank, an intertank section, a 350.7 cubic meter liquid hydrogen tank, and an engine section with two gimballed LOX /LH2 engines of 660 kN vacuum thrust each. The hydrogen tank is pressurised using hydrogen bled from the engine and helium is used to pressurise the oxygen tank.
  • Stage 3. 1 x CZ-NGLV-HO. Gross Mass: 26,000 kg (57,000 lb). Empty Mass: 3,100 kg (6,800 lb). Thrust (vac): 156.000 kN (35,070 lbf). Isp: 448 sec. Burn time: 600 sec. Diameter: 3.35 m (10.99 ft). Span: 5.00 m (16.40 ft). Length: 12.00 m (39.00 ft). Propellants: Lox/LH2. No Engines: 2. Engine: YF-75. Status: Development 2004. The upper stage for the Chinese Next Generation Launch Vehicle is a modification of the CZ-3B upper stage. The stage uses a version of the Lox/LH2 YF-75 engine, simplified for improved reliability. The stage is of hammerhead form, with the upper LH2 tank with a diameter of 5 m, and the lower liquid oxygen tank with a diameter of 3.35 m. The total propellant is 22,900 kg with a burn time of over 600 seconds. Empty mass has not yet been released and is estimated.
