bell-multirole

The Bell 429 is a light, multi-purpose helicopter designed and built by Bell Helicopters and Korea Aerospace Industries. It can be deployed in airborne law enforcement, search and rescue (SAR), emergency medical service, force projection and humanitarian support operations.

The Bell 429 prototype performed its maiden flight in February 2007. The aircraft are currently in operation with a number of police departments and government security agencies across the globe.

The New York Police Department placed a contract with Bell Helicopter for four helicopters in January 2014. The helicopters will be deployed in airborne law enforcement patrol missions. Deliveries are expected to be completed by 2015.

Design and features

The Bell 429 incorporates a new modular airframe and an advanced rotor blade system developed based on the concept of modular affordable product line (MAPL). The aircraft uses the engine and drive system derived from the Bell 427.

The damage tolerant rotor system offers enhanced safety, while collective mounted throttles, energy attenuating seats and one engine inoperative (OEI) performance further improve the survivability.

The helicopter is fitted with 157cm side doors. The cabin compartment measures 5.78m3, including the aft cabin area, and accommodates up to seven passengers and a pilot. The baggage compartment volume is 2.1m3. The helicopter can be reconfigured depending on the mission.

The length of the helicopter is 12.7m, the height is 4.04m and the rotor diameter is 10.97m. Empty and external gross weights are 2,031kg and 3,402kg respectively. The helicopter can carry a useful load of 1,371kg.

Cockpit and avionics of the Bell 429

The glass cockpit of the Bell 429 features BasiX-Pro avionics suite integrating two (or three, optionally) 8inĂ—6in Rogerson Krotas colour liquid crystal multi-function displays and dual digital three-axis autopilot. It also accommodates an integrated electronic data recorder to provide improved situational awareness and post-flight analysis.

Honeywell was selected in February 2006 to provide dual-channel KSG-7200 air data attitude heading reference system (ADAHRS), automatic direction finder (ADF), radar altimeter, weather radar and enhanced ground proximity warning system (EGPWS). The KSG-7200 system is fitted as standard equipment, while the remaining are optional.

The helicopter also incorporates dual Gamin GNS 430 global positioning systems, Bendix King radios, and wide area augmentation system (WAAS).

Engine and performance of the multirole helicopter

The Bell 429 is powered by two PW207D1/D2 turboshaft engines provided by Pratt & Whitney Canada. Each engine produces a power of 820kW. The total usable fuel capacity is 814l.

The helicopter flies at a speed of 278km/h and to a range of over 741km. The hovering out of ground effect (HOGE) ceiling of the Bell 429 is 11,000ft (3,438m).
