Disadvantages of the Osprey Aircraft

  Osprey is a convertible aircraft, with the possibility of combining plane and helicopter characteristics. It was developed in the USA by two World`s leading companies, namely Boeing and Bell. Now it is used in Marine Aviation Corps of the USA and Naval Forces of the USA. This aircraft has two engines Allison T406, which are located on the ends of wings in gondolas which can spin almost at 98 degrees.
   The framework of the Osprey Plane-Helicopter has a very peculiar construction. A great scientific work and research took place in the field of national military Aviation. On constructing of such a plane and a helicopter in one of scientists of Boeing and Bell fulfilled a scope of functional necessities. Screws are interconnected with three trapezoid blades in between synchronizing shaft which passes inside of each wing. The given shaft provides a possibility of landing of the Osprey solely on one engine. With objective of reduction of weight of a design in it composite materials on the basis of carbon and fibreglasses with epoxies are widely used. The upright taking off and landing provides unbeatable advantage especially for Marine Aviation Corps because the whole operation starts and ends from the single ship deck, and not all of the present Marine Corps vessels are capable of facilitating enough space for take-off grounds.
   However, there are certain inconveniences. The force of the engine should be so powerful so as to lift the whole aircraft with crew and the group of Landing Troop. Exhaust air is so strong that it can easily sweep personnel out of the ship`s deck, which makes it too dangerous for people. Moreover, 2-3 minutes of idle run can seriously damage the deck, so that is why laying down steel leafs under the aircraft is a matter of great importance. Two out of six modern Marine vessels are not accustomed to meet these requirements, which is a great demerit for Marine Corps of the US.
   Calibration trials of the aircraft began on March, 19th, in 1989. In 1990 the Task Force decided to equip with these crafts the Marine Corps of the USA, but the initial order in the middle of 1992 was reduced up to 300 planes. The Naval Forces have concluded the contract on purchase of four Ospreys and modernization of two already existing prototypes which it supposed make easier and cheaper.
However, it proved to be very expensive and hard to serve. The US Military Forces lost almost 20 billion dollars on facilitating their Corps with these Aircraft and that is not the end. The problem is that notwithstanding the fact of putting so many efforts in scientific works which proved to be brilliant these aircraft are failed to meet weather oriented requirements: they absolutely useless in areas of deserts and high mountains higher than 3000 meters, particularly the place they were intended to be in use. This huge US government mistake resulted in deplorable consequences.
   The Osprey, which can travel twice as fast and three times farther than the Sea Knight, is equipped with radar, lasers and a missile defence system. Each can carry 24 Marines into combat. Built by Boeing Co. and Bell, a unit of Textron Inc., the Osprey program was nearly scrapped after a history of mechanical failures and two test crashes that killed 23 Marines in 2000.
   In February, a group of 40-plus Ospreys at the Marine Corps' New River Air Station in North Carolina was grounded for several days after a faulty chip was discovered in a new Osprey being tested in Texas.

There will be about 10 to 15 Ospreys per squadron based at Miramar. It was not immediately clear how many personnel would accompany the new aircraft, said Marine Maj. Jason Johnston. Johnston said, that the Osprey squadrons, which included squadrons already based at New River, next to Camp Jejune, were among the first introduced by the Marine Corps since the Harrier. The military plans to eventually operate 458 Ospreys, with 360 for the Marine Corps and the others used by the Navy and Air Force.
