This helicopter paper model is a Bell 222, a twin-engined light helicopter built by Bell Helicopter, the papercraft was created by Mood Indy. The scale of the paper craft model is in 1:24. The Bell 230 is an improved development with different engines and other minor changes. A cosmetically modified version of the 222 was used as the titular aircraft in the American television series Airwolf.
The design includes two main rotor blades of stainless-steel-fiberglass construction and rotor hub with elastomeric bearings, which are lubricant free. Its cabin holds a maximum of 10 persons with 1-2 pilots and 8-9 passengers. Seating configurations include standard seating for a pilot and seven passengers; or executive seating with 1-2 pilots and seating for 5-6. The Bell 222 and 230 are usually flown single-pilot, and can be configured for corporate/executive, EMS or utility transport missions.
The Bell 222 is powered by twin Lycoming/Honeywell LTS101-650 turboshaft engines, rated at 592 shp each. Later 222 versions feature more powerful engines. Engine output is at 100% of rating at 9598 RPM. Two independent drive shafts deliver power from the engines to the transmission. The Bell 222's LST-engine exhaust stacks are located at the rear of the engines, while the 230's Allison-engine exhaust stacks are located high on the cowling. Fuel is stored in three tanks, one in the fuselage and one in each sponson. The main rear landing gear retract into the sponsons.
The Bell 222's rotor systems include:
- Two-blade, semi-rigid high-kinetic energy main rotor with preconing and underslinging. The rotor head incorporates elastomeric bearings for hub springs, flapping and pitch change bearings. The system is similar in design to that used by the AH-1 Cobra. Rotor speed at 100% engine speed is 348 RPM.
- All series models incorporate a pusher-type two-bladed tail rotor mounted on the left side of the tailboom, turning at 3396 RPM.
