Description

The Bell 429 is a twin-engine light helicopter designed, developed and manufactured by Bell Helicopter and Korea Aerospace Industries, based on the Bell 427. Two helicopter mock-up models were first displayed at the Heli-Expo air show in Anaheim in February 2005. First flight of the Bell 429 prototype took place on February 27, 2007, and received type certification on July 1, 2009. The first Bell 429 helicopter was delivered to launch customer Air Methods in August 2009. It was displayed at the Singapore Air Show held in February 2010. In December 2012, announced that it has signed an agreement with the Republic of Turkey Undersecretariat for Defence Industries for the supply of five Bell 429 aircraft. The Bell 429s will be operated by the Turkish General Directorate of Forestry (TGDF) to protect forest resources and coordinate firefighting operations. December 3, 2012, Bell Helicopter announced the delivery of the first Bell 429 from its new Singapore facility. The corporate-configured Bell 429 was delivered to PT Whitesky Aviation in Jakarta, Indonesia. With the latest delivery, PT Whitesky Aviation operates a fleet of five Bell Helicopter aircraft, including two Bell 429s and three Bell 407s.

Design
The cabin of the Bell 429 is exceptionally spacious with seating for up to eight passengers and can be reconfigured for any number of different missions. Designed from the outset as a 21st century airframe, the Bell 429 utilizes an ultra-rigid machined alloy airframe with composite external skins, sharing construction characteristics more commonly found in the most advanced military jets. The result is a spacious, rigid airframe with exceptional resistance to fatigue and adverse environmental conditions. Standard Configuration six-place seating consists of two rows of three energy-absorbing seats, with individual 4-point restraint system, quick release disconnects and fixed provisions for the optional passenger cabin ICS system. The cockpit crew station was designed from the outset to accommodate pilots from the 5th percentile female to the 95th percentile male (standing height 5 ft. ½ inch to 6 ft. 2 inches; sitting height 31.3 inches to 38.3 inches, reference U.S. FAA Human Factors Design Standard, HF-STD-001, dated May 2003). The pilot and co-pilot seats and pedals are also adjustable to enable the cockpit crew to adjust their seat positions for comfortable access to cockpit controls, so that they can easily carry out normal and emergency duties without hindrance. The passenger / cargo compartment occupies the middle section of the cabin. The compartment has a volume of 130 cubic feet (3.68 m3), which can be used in a standard or corporate configuration for passenger seating, or as cargo area. The aft cabin has an additional volume of 74 cubic feet (2.10 m3), giving a total contiguous cabin volume of 204 cubic feet (5.78 m3). A forward hinged and aft sliding door on each side of the cabin provide a 61.9” wide x 44.25” high (158.7 x 112.3 cm) unobstructed door opening on each side of the helicopter for easy passenger compartment loading and unloading. The two forward doors are hinged to open forward and the two sliding doors open aft and flush along the cabin exterior. The passenger/cargo compartment doors can be opened individually or at the same time.
Avionics and equipment
The Bell 429 delivers 155 knot speed with a state-of-the-art cockpit featuring single pilot IFR and WAAS precision approach capabilities. The Bell BasiX-Pro™ Avionics System has been specifically designed to meet the requirements of twin engine helicopters and is optimized for IFR, Category A, and JAROPS-3 compliant operations. The system is highly flexible and configurable to meet various operating and customization needs. The system takes advantage of the latest in display, computer processing, and digital data bus technology to provide a high degree of redundancy, reliability, and flexibility. The standard configuration for the Bell 429 provides single-pilot IFR capability with 3-axis stability and control augmentation (SCAS) and a coupled flight director capability. All Engine Indication and Crew Alerting System (EICAS) display functions are provided through the Bell BasiX-Pro™ Avionics System. The system works in conjunction with the engine control units (EECs) for the dual Pratt & Whitney electronically-controlled PW- 207D1 engines. Other aircraft systems interfaces, warnings, cautions, aural alerts, and automated performance features are provided through the remotely located Aircraft Data Interface Unit (ADIU). The Bell 429 standard configuration for Communications Navigation and Surveillance (CNS) consists of dual Garmin GNS-430W NAV/COM/WAAS GPS systems, with a kit option to replace one of these with a GNS-530W. The standard system also includes a GTX-330 ELS compliant Mode S transponder, a PMA-7000H Audio/Intercom Panel with VOX and Integral Marker Beacon Receiver, and an ARTEX C406-N-HM Emergency Locator Transmitter (ELT).
Propulsion
The Bell 429 is powered by two turboshaft engines, type PW207D1 by Pratt & Whitney Canada, each rated at 820kW (1,100shp). The Bell 429 has a 4-blade rotor system with soft-in-plane flex beams. The rotor blades are composite and have swept tips for reduced noise. The tail rotor is made by stacking two, two-blade rotors set at uneven intervals (to form an X) for reduced noise. The maximum cruise speed is 287km/h and the range on internal fuel is 645km. Its cruise speed is 278km/h. The hover ceiling (OGE) is 2,835m. The aircraft has an empty weight of 2,007kg. The maximum take-off weight is 3,175kg. The maximum altitude and range of the Bell 429 are 6,096m and 722km respectively. The maximum endurance at maximum gross weight 4,000ft ISA is four hours.
Mission capabilities
Fast, agile, smooth and quiet, the Bell 429 reduces response time and crew fatigue while expanding an agency’s mission capabilities. Exceptional cabin volume, large cabin doors and optional rear clamshell doors easily accommodate special mission equipment, tactical deployments or hoist operations. Even the tallest crew member wearing an NVG equipped helmet is comfortable flying the Bell 429 thanks to best in class cabin volume and fully adjustable seats and pedals. Coupled with a fully integrated glass cockpit, with options that include moving maps, FLIR imagery and NVG capability, the Bell 429 delivers the complete multi-role Parapublic package.
