We lost our tail rotor!
SA 340 First prototype, first flown on 7April 1967 with a conventional Alouette type tail rotor.
Diameter of tail rotor, m 3.84.
The S-67 featured a five-bladed main rotor and tail rotor.
Fuel lines, control cables and power to the tail rotor may also be shrouded by Kevlar armour.
Explorer with the patented NOTAR system- without tail rotor.
Since the tail rotor is driven by the main rotor transmission during autorotation, heading control is maintained as in normal flight.
The height of the helicopter on the parking lot without tail rotor, m 3,75.
Single rotor helicopters need a tail rotor to neutralize the twisting moment produced by the single large rotor. .
Sikorsky's major contribution to practical helicopter flightwas his tail rotor configuration.
The French part of Eurocopter(former helicopter division of Aérospatiale-Matra group)brought his side the tail rotor type fenestron allows a further reduction of the noise level and brings great advantages from the point of view of security personnel on the ground.
Investigation established that used by thepilot mechanisms of management it lost touch with a tail rotor.
The tail configuration wasalso changed to a larger vertical tail with the tail rotor tilted slightly to provide some lift in hover.[6].
Like the Bell 407, the 427 uses a four-blade main rotor system with a rigid,composite rotor hub and a two-blade tail rotor.
Sikorsky submitted the S-66, which featured a"Rotorprop" serving as a tail rotor but as speeds increased would rotate 90° to act as pusher prop.
Had 212 nose, uprated T53-17 engine, K-Flex driveshaft,212 main rotor blades, tail rotor blades.
The low-mounted symmetrical horizontal tail was replaced by a larger vertical tail and the tail rotor tilted from the vertical to provide some lift in hover while counteracting the main rotor torque.
The Bell 400 TwinRanger featured a reprofiled fuselage, two Allison 250turboshafts, the OH-58D Kiowa's four-bladed main rotor, and a new shrouded tail rotor.
The tail rotor is made by stacking two, two-blade rotors set at uneven intervals(to form an X) for reduced noise.[3] The combined cabin volume is 204 ft³(5.78 m³) with a 130 ft³ passenger cabin and 74 ft³ baggage area,[6] with a flat floor for patient loading.
When the program was over, the aircraft was returned to MBB Canada BK 117 A-4 Introduced in July 1986, the A-4 has increased transmission limits at take-off power,improved tail rotor head.
Global Eagle Pratt& Whitney Canada name for a modified UH-1H with a new PT6C-67D engine,modified tail rotor, and other minor changes to increase range and fuel efficiency over the Bell 212.[12] Huey 800 Upgraded commercial version, fitted with an LHTEC T800 turboshaft engine.
As the Sikorsky S-80 it was developed from the CH-53 Sea Stallion, mainly by adding a third engine,adding a seventh blade to the main rotor and canting the tail rotor 20 degrees.
Almost immediately after leaving the stadium, the helicopter entered a spin and fell to the ground.[18]A witness claimed that the failure of the helicopter's tail rotor was the cause of the accident,[6] with another witness stating the aircraft fell"like a stone to the floor".[19] The helicopter struck the ground in stadium Car Park E, about 200 metres(200 yd) from the stadium.
The Bell 427 is powered by two Pratt& Whitney Canada PW207D turboshaft engines with FADEC.[2] Like the Bell 407, the 427 uses a 4-blade main rotor system with a rigid,composite rotor hub and a 2-blade tail rotor.[2].
Advanced 205B- Proposed upgraded Japanese version.[citation needed] Global Eagle- Pratt& Whitney Canada name for a modified UH-1H with a new PT6C-67D engine,modified tail rotor, and other minor changes reported to increase range and fuel efficiency over the Bell 212.[4] Huey 800- Upgraded commercial version, fitted with an LHTEC T800 turboshaft engine.
In October 1988, the Boeing-Sikorsky and Bell-McDonnell Douglas teams received contracts for their designs.[5] The Bell-McDonnell Douglas designfeatured ordnance carriage within a combined wing/sponson and instead of a tail rotor used a NOTAR ducted exhaust system.
The Bell 400 TwinRanger featured a reprofiled fuselage, two Allison 250turboshafts, the OH-58D Kiowa's four blade main rotor, and a new shrouded tail rotor.[1] Bell also planned the single-engined 400A, and the 440 twin with a larger fuselage made possible by a high degree of composites.[2] The Bell 400 first flew on April 4, 1984.
Initially the machine was designed for the certification and sale on the international market, so the Mi-38 has a lot of advanced features, such as the glass cockpit(English glass cockpit) for the two pilots, electronic control system and extensive use of composite materials,including the carrier and The tail rotor.
As part of internal Sikorsky R&D efforts, in 1974 the S-67 had a 3.5-foot-diameter(1.1 m)ducted fan fitted instead of its original conventional tail rotor.[3] The S-67 with fan was tested over 29 flight hours to compare to the conventional tail.[13] In this configuration it reached a speed of 230 mph(370 km/h) in a test dive.[3] The original tail rotor and vertical tail fin were re-installed in August 1974.
Sikorsky has announced its major subcontractors: Aurora Flight Sciences(main rotor pylon),[14]Exelis Aerostructures(tail rotor pylon and sponsons),[14] GKN Aerospace(aft transition),[14] Onboard Systems International(external cargo hook system),[15] Rockwell Collins(avionics management system),[16] Sanmina-SCI Corporation(Intercommunications System), and Spirit AeroSystems(cockpit and cabin).[14].
