| Source measurement | — | The HH-65 Dolphin is used for homeland security patrols, cargo , drug interdiction , ice breaking , military readiness, pollution control , and search and rescue missions. The HH-65 is known for its Fenestron tail rotor and its autopilot capabilities, which can complete an unaided approach to the water and bring the aircraft into a stable 50 ft (15 m) hover, or automatically fly search patterns, an ability which allows the crew to engage in other tasks.[source]Eurocopter MH-65 Dolphin · Development; only the objects and conditions stated in this passage The HH-65A's minimum equipment requirements exceeded anything previously packaged into a helicopter weighing less than 10,000 pounds (4,535 kg). Seventy-five percent of the HH-65's structure—including rotorhead, rotor blades and fuselage—consists of corrosion-resistant composite materials.[source]Eurocopter MH-65 Dolphin · Design; only the objects and conditions stated in this passage Also a unique feature of the Dolphin is its computerized flight management system, which integrates state-of-the-art communications and navigation equipment. This system provides automatic flight control. At the pilot's direction, the system will bring the aircraft to a stable hover 50 feet (15 m) above a selected object. This is an important safety feature in darkness or inclement weather. Selected search patterns can be flown automatically, freeing the pilot and copilot to concentrate on sighting & searching the object.[source]Eurocopter MH-65 Dolphin · Design; only the objects and conditions stated in this passage On 16 September 1996 one crashed in the Mediterranean during a joint night training exercise with two squadrons, Eurocopter HH-65 Dolphin helicopter number 905 crashed about 12 miles (19 kilometers) west of the coast of Nahariya .[source]Eurocopter MH-65 Dolphin · Operational history / Israeli Air Force service; only the objects and conditions stated in this passage Initial USCG version, powered by two 734 shp (547 kW) LTS101-750B-2 turboshaft engines and with an 8,900 lb (4,000 kg) MTOW.[source]Eurocopter MH-65 Dolphin · Variants; only the objects and conditions stated in this passage Avionics upgrade undertaken on a portion of the fleet. Retrofit included an NVG -compatible integrated flight management avionics suite consisting of two GPS-embedded CDU-900G control display units and two MFD-255 multifunction flat panel displays. The HH-65B upgrade was undertaken at the Coast Guard's Aircraft Repair and Supply Center (ARSC) in Elizabeth City , NC, with the first aircraft rolling-off the post-depot maintenance (PDM) line in March 2001.[source]Eurocopter MH-65 Dolphin · Variants; only the objects and conditions stated in this passage HH-65A/B upgraded with new 934 shp (696 kW) Arriel 2C2-CG engines that provide 40% more power and higher performance, plus an upgraded tail gearbox, long-nose avionics compartment, increased 9,480 lb (4,300 kg) MTOW, expanded lateral flight envelope and Vehicle and Engine Multifunction Display (VEMD) with First Limit Indicator (FLI). First retrofit completed in October 2004.[source]Eurocopter MH-65 Dolphin · Variants; only the objects and conditions stated in this passage Initially intended only for use by the Multi-Mission Cutter Helicopter (MCH), a further enhancement of the HH-65C within the USCG's Deepwater effort, includes the installation of a 10-blade low-noise Fenestron, relocated avionics, and an Airborne Use of Force (AUF) package (in common with that of the modernized HH-60T) which provides the capability to fire warning and disabling shots from the air. The MH-65C is used in AUF missions, such as the Helicopter Interdiction Tactical Squadron (HITRON) mission taken up by the MH-65C in early 2008. AUF aircraft are armed with the Barrett M107CQ 12.7 mm anti-materiel rifle and M240G 7.62 mm machine gun. The helicopter can also be used for counter terrorism.[source]Eurocopter MH-65 Dolphin · Variants; only the objects and conditions stated in this passage MH-65C with an upgraded flight navigation system common to Department of Defense helicopters. The first production MH-65D was completed on 20 January 2011 and is fitted with a Honeywell HG7502 radar altimeter, two Honeywell H-764G EGI's (embedded GPS/inertial navigation systems) and two control display units CDU-7000D from Rockwell Collins. 97 HH/MH-65Cs will be upgraded to MH-65D standard.[source]Eurocopter MH-65 Dolphin · Variants; only the objects and conditions stated in this passage Length: 11.6 m (38 ft 1 in)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Height: 4 m (13 ft 1 in)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Empty weight: 3,128 kg (6,896 lb)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Max takeoff weight: 4,300 kg (9,480 lb)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Powerplant: 2 × Turbomeca Arriel 2C2-CG turboshaft engines, 636 kW (853 hp) each[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Main rotor diameter: 11.9 m (39 ft 1 in)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Main rotor area: 111.22 m 2 (1,197.2 sq ft)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Maximum speed: 330 km/h (210 mph, 180 kn)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Cruise speed: 240 km/h (150 mph, 130 kn)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Range: 658 km (409 mi, 355 nmi)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage Service ceiling: 5,486 m (17,999 ft)[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage 1 x 7.62 mm M240 machine gun[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage 1 x Barrett M107 0.50 in (12.70 mm) caliber precision rifle[source]Eurocopter MH-65 Dolphin · Specifications (MH-65C); only the objects and conditions stated in this passage |
