Quality die cast 1:55 scale model of the CHD 47 Chinook. It is a medium lift tandem rotor helicopter. It features folding tandem tail rotors, opening tail ramp and stand. It is approx 16” x 8”.
The CH-47 is a twin-engine, tandem rotor helicopter. The “D” model can carry up to 26,000 pounds externally or a wide variety of internal payloads, including vehicles, artillery pieces, 33 to 44 troops, or 24 litters plus two medical attendants. The fuselage is approximately 50’. With a 60-foot rotor span per blade system, the effective length of a CH-47 (blades turning) is almost 100 feet.
The CH-47 Series Chinook began development in 1956. The CH-47D resulted from a June 1976 contract requiring a modernized Chinook. The CH-47D rolled-out in March 1979. Improvements included upgraded power plants, rotor transmissions, transmission systems integral lubrication and cooling, fiberglass rotor blades, a redesigned cockpit reducing pilot workload, redundant and improved electrical systems, modularized hydraulic systems, an advanced flight control system, and improved avionics.
A minimum tactical operations crew is four (two pilots, one flight engineer and a crew chief). Commanders may use five crew members (an additional crew chief) for complex missions such as NVG operations and air assaults.
Two Allied Signal Engines T55-L-712 3750 hp turboshaft engines power the CH-47D producing a maximum speed of 163 mph (142 knots). The CH-47D carries twice the load of a CH-47A and has improved performance. The CH-47D operates at night and in nearly all weather conditions.
The Chinook can carry two door mounted M240D 7.62mm machine guns on the M24 armament subsystem and a ramp mounted M240D using the M41 armament subsystem.
During Desert Storm, the CH-47D shifted large numbers of personnel, equipment, and supplies rapidly over vast areas in which US forces operated. Forward Operating Base Cobra was positioned to accommodate the combat radius of a fully loaded CH-47D. Cobra was initially secured by an air assault of the 101st’s 2nd Infantry Brigade. This air assault consisted of 5000 soldiers using 126 Blackhawks and 60 Chinooks. At the end of the first day, the CH-47Ds had lifted 131,000 gallons of fuel along with pallets of combat-configured ammunition.
The CH-47D enjoys wide use in Afghanistan and Iraq. It is typically escorted by attack helicopters like the AH64 Apache for protection. The CH-47D is particularly useful in the mountainous terrain of Afghanistan where high altitudes and temperatures limit UH60 Blackhawk use. The Chinook conducted air assault missions, inserting troops into fire bases and later bringing food, water, and ammunition.
