Chlorodifluoromethane or difluoromonochloromethane is a hydrochlorofluorocarbon (HCFC). This colorless gas is better known as HCFC-22, or R-22, or CHClF 2.It was commonly used as a propellant and refrigerant.
Fuel capacity: Main tank total capacity: 16.9 US gal (14 imp gal; 64 L) Optional auxiliary tank total capacity: 10.9 US gal (9 imp gal; 41 L) Powerplant: 1 × Lycoming O-320-A2B or -A2C 4-cylinder air-cooled horizontally-opposed piston engine, 124 hp (92 kW) Main rotor diameter: 25 ft 2 in (7.67 m) Main rotor area: 497 sq ft (46.2 m 2)
The three-zone (reduced from four from the prototype) afterburner, or augmentor, contributes to the stealth of the aircraft by having fuel injectors integrated into thick curved vanes coated with ceramic radar-absorbent materials (RAM). These vanes replace the traditional fuel spray bars and flame holders and block line-of-sight of the turbines.
For example, R-22 has one carbon atom, one hydrogen atom (2−1 = 1), two fluorine atoms, and one chlorine atom (4−2−1 = 1), so it is chlorodifluoromethane, while R-134 has two carbon atoms (2−1 = 1), two hydrogen atoms (3−1 = 2), four fluorine atoms, and no chlorine atoms (6−2−4 = 0), so it is one of the tetrafluoroethanes. This ...
