Bell UH-1Y Venom

Design and development

In 1996, the United States Marine Corps launched the H-1 upgrade program by signing a contract with Bell Helicopter for upgrading 100 UH-1Ns into UH-1Ys and upgrading 180 AH-1Ws into AH-1Zs. The H-1 program created completely modernized attack and utility helicopters with considerable design commonality to reduce operating costs. The UH-1Y and AH-1Z share a common tailboom, engines, rotor system, drivetrain, avionics architecture, software, controls and displays for over 84% identical components.

 

Over the years new avionics and radios, in addition to modern door guns and safety upgrades, have greatly increased the UH-1N's empty weight. With a maximum speed of approximately 100 knots (190 km/h) and an inability to lift much more than its own crew, fuel and ammunition, the UH-1N, while useful, is limited in its utility.

The Y-model upgrades pilot avionics to a glass cockpit, adds further safety modifications and provides the UH-1 with a modern FLIR system. However, the biggest improvement is an increase in engine power. By replacing the engines and the two-bladed rotor system with four composite blades, the Y-model will return the Huey to the utility role for which it was designed. Originally the UH-1Y was to have been remanufactured from UH-1N airframes, but in April 2005 approval was granted to build them as new helicopters.

The Y-model updates an airframe that has been central to Marine Corps aviation in Iraq.[citation needed] The Huey has many mission requirements including command and control (C2), escort, reconnaissance, troop transport, medical evacuation and close air support. Typically detachments of two to four Hueys have been deployed with detachments of four to eight Cobras.The forward-mounted weaponry of the Cobra combined with the door guns of the Huey provides a 240° field of fire.

Bell delivered two UH-1Ys to the U.S. Marine Corps in February 2008 and full-rate production was begun in September 2009. The Marine Corps plans to buy 160 Y-models to replace their inventory of N-models.

The UH-1Y variant modernizes the UH-1 design. Its most noticeable upgrade over previous variants is a four-blade, all-composite rotor system designed to withstand up to 23 mm rounds. A 21-inch (530 mm) fuselage extension just forward of the main door has been added for more capacity. The UH-1Y features upgraded engines and transmissions, a digital cockpit with flat panel multifunctional displays, and an 84% parts commonality with the AH-1Z. Compared to the UH-1N, the Y-model has an increased payload, almost 50% greater range, a reduction in vibration, and higher cruise speed

Bell UH-1Y Venom

The Bell UH-1Y Venom (also called Super Huey is a twin-engine, medium-sized utility helicopter, built by Bell Helicopter under the H-1 upgrade program of the United States Marine Corps. One of the latest members of the numerous Huey family, the UH-1Y is also called "Yankee", based on the NATO phonetic alphabet pronunciation of its variant letter. The UH-1Y was to have been remanufactured from UH-1Ns, but in 2005, it was approved for the aircraft to be built as new. After entering service in 2008, the UH-1Y is currently in full-rate production to replace the USMC's aging fleet of UH-1N Twin Huey light utility helicopters, first introduced in the early 1970s

Over 60 civil Model 204B helicopters had been delivered by 1967, while further examples were built by Agusta-Bell until 1973. 12,000 Model 205s (including civil 205A-1s) were built by Bell and Agusta-Bell up to the early 1980s. Numerous ex-military 204s and 205s were converted for commercial use.
