Helicopter Forward Flight





helicopter forward flight






    helicopter
  • an aircraft without wings that obtains its lift from the rotation of overhead blades

  • A helicopter is a type of rotorcraft in which lift and thrust are supplied by one or more engine driven rotors. In contrast with fixed-wing aircraft, this allows the helicopter to take off and land vertically, to hover, and to fly forwards, backwards and laterally.

  • A type of aircraft that derives both lift and propulsion from one or two sets of horizontally revolving overhead rotors. It is capable of moving vertically and horizontally, the direction of motion being controlled by the pitch of the rotor blades

  • HElicopTEr is the ninth studio album by the post-industrial electronic band Download. HElicopTEr strays away the group's two previous albums FiXer and Effector in that it is less ambient and more experimental.





    forward
  • at or near or directed toward the front; "the forward section of the aircraft"; "a forward plunge down the stairs"; "forward motion"

  • the person who plays the position of forward in certain games, such as basketball, soccer, or hockey

  • Directed or facing toward the front or the direction that one is facing or traveling

  • (in sports) Moving toward the opponents' goal

  • at or to or toward the front; "he faced forward"; "step forward"; "she practiced sewing backward as well as frontward on her new sewing machine"; (`forrad' and `forrard' are dialectal variations)

  • Positioned near the enemy lines





    flight
  • a formation of aircraft in flight

  • Shoot (wildfowl) in flight

  • shoot a bird in flight

  • (in soccer, cricket, etc.) Deliver (a ball) with well-judged trajectory and pace

  • an instance of traveling by air; "flying was still an exciting adventure for him"

Investigation of Increased Forward Flight Velocities of Helicopters Using Second Harmonic Control and Reverse Velocity Rotor Concept


Investigation of Increased Forward Flight Velocities of Helicopters Using Second Harmonic Control and Reverse Velocity Rotor Concept



This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A946024. The abstract provided by the Pentagon follows: Described is the behavior of a rotorcraft equipped with Higher Harmonic Stall Control (HHSC) and a Reverse Velocity Rotor (RVR). Current rotorcraft are limited in forward flight speed by retreating blade stall and compressibility effects on the advancing blade. Stall occurs as the blade encounters increasingly severe reverse flow. HHSC enables conventional rotor systems to fly on the forward and aft sections of the rotor disk, greatly reducing reliance on the mixed flow regions defined by the advancing and retreating blades. Employment of the RVR allows lift generation while the rotor is experiencing reverse flow. A similar type of two per revolution (2/rev) input can be tailored to deliver maximum benefit to RVR equipped rotorcrafi. Modification of the Joint Army Navy Rotorcraft Analysis and Design (JANRAD) computer program allows 2/rev cyclic input, use of the RVR, and analysis using high fidelity graphical output to examine angle of attack, coefficient of lift, and air load. Computational results show performance gains in conventional helicopters and high speed flight potential for RVR equipped aircraft. The RVR is applied to the Joint Heavy Vertical Lift (JVHL) aircraft conceptual design for preliminary analysis. This conceptual design can be used as an indicator of the performance% of a high speed RVR equipped aircraft.

Helicopter





A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors, each rotor consisting of two or more rotor blades. Helicopters are classified as rotorcraft or rotary-wing aircraft to distinguish them from fixed-wing aircraft because the helicopter derives its source of lift from the rotor blades rotating around a mast. The word 'HELICOPTER' is adapted from the French helicoptere, coined by Gustave de Ponton d'Amecourt in 1861.

As an aircraft, the primary advantages of the helicopter are due to the rotor blades that revolve through the air, providing lift without requiring the aircraft to move forward the way an airplane does. This creates the ability for the helicopter to take off and land vertically without the need for runways. For this reason, helicopters are often used to operate in congested or isolated areas where airplanes are generally not able to take off or land. The lift from the rotor also allows the helicopter to hover in one area for extended periods of time, and to do so more efficiently than other forms of vertical take-off and landing (VTOL) aircraft, making it useful in accomplishing tasks that airplanes are not able to perform.

Although helicopters were developed and built during the first half century of flight, some even reaching limited production, it wasn't until 1942 that a helicopter designed by Igor Sikorsky became the first helicopter to enter full-scale production, totaling over 400 copies. Even though most previous designs utilized more than one main rotor, it was the single main rotor with antitorque tail rotor configuration of this design that would come to be recognized worldwide as the helicopter
