Development

In 1974, the new Bell 222 was announced by Bell. It was the first light commercial twin engine helicopter developed in the United States. ^[1]

The 222, which first flew on August 13, 1976, incorporated a number of advanced features including dual hydraulic and electrical systems, stub wings housing the retractable undercarriage, and the Noda Matic vibration reduction system developed for the 214ST. Events 3114 BC - According to the Lounsbury correlation the start of the Maya calendar. Year 1976 ( MCMLXXVI) was a Leap year starting on Thursday (link will display full calendar of the Gregorian calendar. Certificated in December 1979, deliveries of the 222 began in early 1980. ^[1]

The more powerful Bell 222B was introduced in 1982 with a larger diameter main rotor. The 222B-based Bell 222UT Utility Twin, with skid landing gear, was introduced in 1983. ^[1]

A development of the 222 is the Bell 230, with the 222's LTS 101 engines replaced by two Allison 250 turboshafts, plus other refinements.

A converted 222 first flew as the prototype 230 on August 12, 1991. Events 1099 - First Crusade: Battle of Ascalon - Crusaders under the command of Godfrey of Bouillon defeat Fatimid Year 1991 ( MCMXCI) was a Common year starting on Tuesday (link will display full calendar of the Gregorian Calendar. Transport Canada awarded certification in March 1992, and the first production 230 was delivered that November. The 230 had optional skid or wheel undercarriage. Production ended in 1995 with 38 having been built, being replaced in Bell's lineup by the stretched, more powerful Bell 430. WikipediaWikiProject Aircraft.

Design

The Bell 222 and 230 are usually flown single-pilot (optional dual controls are available), and can be configured for corporate/executive, EMS or utility transport missions. The aircraft have standard seating for eight, including pilot, in four rows. Alternative seting includes four in main cabin in club configuration. ^[1]

Powerplants

Engine output is 100% rated 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.

Rotor systems

• 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 tailrotor mounted on the left side of the tailboom, turning at 3396 RPM

Variants

Bell 222 

The original Model 222, sometimes unofficially called a Bell 222A to distinguish it from the Bell 222B. An Aircraft constructed with a pusher configuration has the engine mounted forward of the Propeller - which faces in a rearwards direction - giving an appearance The Air Support Unit (ASU provides aerial reconnaissance and other air support operations for the Metropolitan Police Service over London and its suburbs It was powered by two (461kw takeoff rated, 441kW max continuous rated) Honeywell (formerly Lycoming) LTS-101-650C-3 turboshafts. Honeywell ( is a major American multinational conglomerate company that produces a variety of consumer products engineering services and aerospace systems The Honeywell (formerly Lycoming LTS101 is a Turboshaft engine family ranging from 650 to 850 shaft horsepower used in a number of popular helicopters and (as the LTP101 A turboshaft engine is a form of Gas turbine which is optimized to produce Shaft power, rather than Jet thrust.

Bell 222B 

In 1982 the 222 was given a power upgrade (two 505kW (takeoff rated) Honeywell (formerly Lycoming) LTS-101-750Cs), a larger main rotor, and was renamed the Bell 222B.

Bell 222B Excutive 

This model had improved systems and a luxury interior.

Bell 222UT 

A 222B variant with skids, introduced in 1983.

Bell D-292 

The Advanced Composite Airframe Program (ACAP) was a 1985 all-composite LHX proof of concept project. The Bell D-292 used the Avco Lycoming engines, transmission, two-bladed main and tail rotors, tailboom, vertical fin, and rotor pylon of the 222. The new airframe used composite materials in place of metal to provide greater strength, lighter weight, lower manufacturing costs, and reduce maintenance costs. ^[2]

Bell 230 

In 1991 the 222B design was updated, given more powerful engines, and renamed the Bell 230. Production ended in 1995.

Bell 230 Excutive 

Excutive transport version.

Bell 230 Utility 

Utility transport version.

Bell 230 EMS 

Air ambulance version, equipped with one or two strechers.

Bell 222SP 

During the 1990s, a number of 222s were modified to use the 230's Allison engines as an after-market STC due to reliability issues with the Lycoming engines, and redesignated as 222SPs.

Operators

In addition to the large number of civil operators, a small number of Bell 222 family helicopters have entered military service. One served with Albania from 1979 to 2001.
