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.

Helicopter Design for MDX name was started by McDonnell-Douglas in 1988 and carried out in parallel with the launch of mass production, development, testing first helicopter equipped with NOTAR system, in which the purpose of balancing the torque reactive torque of the main rotor is used thruster, and not the tail rotor . Experience that is obtained when creating a data helicopters used in fully MD900 structure.

The first flight of the helicopter was 18.12.1992. The helicopter was built on a single-screw scheme, equipped with a NOTAR system and a power twin-engine installation. In view of the fact that the power unit is located above the fuselage, and not in the fuselage, as is customary in the past models of the McDonnell Douglas multipurpose helicopters, almost all the interior space of the fuselage can be used as a cargo cabin and crew cabin. In the cockpit there are two seats for pilots or for the passenger and the pilot ≈ depending on the destination of the helicopter. Behind the crew cabin is a cargo cabin, which is not separated, as a rule, from the cockpit by a partition.

Here you can install up to six passenger seats for passengers or place two stretchers for patients. In view of the fact that the cockpit floor is made at the same level, the helicopter can be used for transporting goods on standard cargo pallets of the required dimensions. Loading of bulky cargo is carried out through the cargo hatch, on both sides of the fuselage there are also doors that are mounted on hinges for access to the cockpit, and access to the cargo cabin is through two sliding doors, the size of which is 1.2x1.27m. Behind the fuselage, a tail boom, equipped with a jet plane NOTAR, is mounted on which is mounted a stabilizer with end sweep washers. Due to the wide use in the fuselage design of composite modern materials (Kevlar, carbon fiber, glass fibers) and lighter alloys, designers have been able 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.

Thanks to the use of two motors in the power plant and the ability to continue flying on one engine, when another engine fails, the helicopter has higher operational reliability than the previous models of the MD500 / 530 helicopters. The first production helicopters installed Pratt & Whitney PW206B gas turbine engines with take-off power of 465kW. each. You can also install dvigateleyTurbomecaTM319. The capacity of the system with fuel is 602l. Rotor the helicopter has five blades in terms of a rectangular shape. The blades are made of composite materials and are lining erosion.
