A new kind of urban transport

 

 

Although, strictly speaking, its layout is not entirely new form of transport. According to this scheme tiltrotor.

 

tiltrotor - an aircraft with rotary thrusters (as a rule, screw), which during takeoff and landing work as lifting, and in level flight - as pulling; while the lift is provided by an airplane wing. Usually, the motors turn with the propellers, but only the propellers can turn.

Konvertoplanov long been engaged in aircraft designers in many countries. Further design and prototyping business, as a rule, do not go. There were a lot of difficulties with the wing rotation units with motors or engines with propellers themselves separately.

Suffice it to recall the famous designs konvertoplanov.

This so-called tilt-rotor tiltrotor Bell XV-3. Tiltrotor is built upon the company Bell for testing the basic components and screws turning mechanisms.

Conventionally tiltrotor divided into two types: with rotary wing, where engines are installed with screws (tiltwing), and tiltrotor tilt-rotor (tiltrotor).

Modern tiltrotor joint development Bell\Agusta BA609. Several accidents have occurred in recent years, delaying the launch of promising tiltrotor into production.

The world's only commercially available tiltrotor (tiltrotor) firms Bell V-22 Osprey. Development continued over 30 years. Now V-22 Is armed Marine Corps and the US Navy.

In the Soviet Union, too, has not paid attention to this topic. In 1972 year Mil. ML Mil Mi-30 project was created. Multipurpose tiltrotor, was called upon in the future to replace the ubiquitous Mi-8. As the power plant we have used all the same engines that are installed on the Mi-8, TV3-117. But vintoplan (as it was called in the USSR) Mi-30 never advanced beyond design studies. The collapse of the USSR, securely buried promising project.

TriFan 600

And now, the American designers of the company XTI Aircraft developed a commercial 6 and local (5 + pilot) TriFan 600 convertor. The device will have three turbo-engines Honeywell Aerospace HTS-900. Two of them will be fastened on the leading edge of the bearing wing, on a fork-like fastening. Such a fastening will allow the fan in the ring fairing to rotate, providing the desired mode. The third rotary fan is located behind the passenger cabin, similar to the air-cushion discharge rotor of the ship. The stern rotor will provide the necessary thrust on the takeoff and landing mode. When moving to a horizontal flight, the third rotor will be closed with a special shield.

Manufacturers of new technology position it as a means of transportation for business people, for top managers, for people who value their time. The tiltrotor cabin can comfortably accommodate 4 people in the chairs facing each other, the fifth passenger will take a seat next to the pilot. The tiltrotor must successfully combine the advantages of a helicopter and an airplane. A sufficient speed (640 km / h) and a flight range of up to 2575 km can be very attractive for businessmen to move quickly on business trips. Takeoff and landing by helicopter provides additional advantages for using the device in urban conditions. For takeoff and landing, just a solid platform of a certain size is enough. It can be the lawn of a country house and the roof of a business center or a skyscraper where there are already helipads.

Flight tests TriFan 600 plan to spend next summer. For the full completion of the project and design work requires serious funding. According to various estimates this amount 400-450 million. Dollars. Certification presumably can be passed only through 6 years.

 

 

The new aircraft can be used for emergency assistance for tourism (not cheap), in business trips. The sale of the unit will go for the price of $ 10-12 million.. But as long as manufacturer is looking for investors to continue work on the perspective view of urban transport.

Expensive, dangerous, ineffective and very noisy car will never make the project commercially successful.
