MD Helicopters MD Explorer

In 1988 helicopter branch of McDonnel Douglas start designing a new generation of multi-purpose helicopter, equipped with NOTAR system for military and civilian use. Helicopter MD 900 Explorer can equally well be used as a utility for the execution of civil transportation and military purposes in order to ensure communication and observation, fire support of the army and fight with tanks.

The design of the helicopter under the name MDX was launched by McDonnell-Douglas at 1988 and was carried out in parallel with the launch into mass production, development, testing of the first helicopters equipped with the NOTAR system, in which a jet screw rather than a steering screw is used to balance the torque of the rotor. . The experience gained in creating these helicopters has been fully utilized in the construction of MD900.

The first flight of the helicopter was 18.12.1992. The helicopter was built according to a single-rotor scheme, equipped with a NOTAR system and a twin-engine power plant. Due to the fact that the power plant is located above the fuselage, and not in the fuselage, as is customary in past models of McDonnell Douglas multi-purpose helicopters, almost all the internal space of the fuselage can be used as a cargo compartment and crew cabin. In the cockpit, two chairs are set up for pilots, or for a passenger and a pilot, depending on the purpose of the helicopter. Behind the cabin of the crew is a cargo cabin, which is not separated, as a rule, from the crew cabin by a partition.

Here you can install up to six passenger seats for passengers or place two stretchers for patients. Due to the fact that the cabin floor is on the same level, the helicopter can be used to transport cargo on standard cargo pallets of the required size. Bulky cargo is loaded through the rear cargo hatch, there are also hinged doors on both sides in front of the fuselage for access to the crew cabin, and access to the cargo cabin is through two sliding doors 1.2X1.27. A tail boom is attached to the rear of the fuselage, equipped with a NOTAR jet, on which a stabilizer with end arrow washers is mounted. Due to the widespread use of composite modern materials in the fuselage design (Kevlar, carbon fiber, fiberglass) and lighter alloys, the designers managed to significantly reduce its mass.

In the helicopter skid landing gear, which can be modified according to the customer on a wheeled chassis. In order to permit landing on water, can be installed inflatable ballonets.

Due to the use of two engines in the power plant and the ability to continue flying on one engine, when the other engine fails, the helicopter has a higher operational reliability than previous models of helicopters such as MD500 / 530. On the first production helicopters, Pratt & Whitney PW206B gas turbine engines were installed with an take-off power of 465 kW. each. Installation of TurbomecaТМ319 engines is also possible. The capacity of the fuel system is 602. The rotor at the helicopter has five blades in the plan of a rectangular shape. The blades are made of composite materials and have anti-erosion linings.
