Principles of Helicopter Aerodynamics with CD Extra
5.4.7 Tail Rotor Power The power required by the tail rotor typically varies
between 3 and 5% of the main rotor power in normal flight, and up to 20% of the
main rotor power at the extremes of the flight envelope. It is calculated in a similar
way ...
Alternatively the drum may be replaced with a sprocket engaging a length of
roller chain inserted in the wire. An elegant improvement is to couple the
collective pitch setting into the tail rotor pitch controls so that to some extent
torque variations ...

In-flight Array Measurements of
Tail Rotor Harmonic Noise
The averaged time histories of the isolated model tail rotor and of the combined
main/tail rotor was inspected for signs of the main rotor wake/tail rotor interaction.
The work reported, “no significant main rotor tip vortex/ tail rotor interference ...

HOT-AIR CHOPPER shaft which turns the main rotor. Without the tail rotor to
keep things straight, the airframe would spin in the opposite direction of the main
rotor. The Voljet 585 has a 1050-shaft- horsepower Pratt & Whitney PT6C-60

Basic Helicopter Handbook
Antitorque pedals The thrust produced by the auxiliary (tail) rotor is governed by
the position of the anti- torque pedals. These pedals are located as shown in
figure 27. They are linked to a pitch change mechanism in the tail rotor gear box
to ...

Failure Analysis of Engineering Structures: Methodology and ...
Summary. The outboard rib of a tail rotor blade in a helicopter became separated
in flight, causing severe vibrations. The rivets for fitting the rib to the blade were
also missing. The skin of the blade was found torn off at a number of rivet holes.

Rotorcraft Aeromechanics
On many helicopters the tail rotor is a source of high noise, but there are design
choices to alleviate the noise, especially lower tip speed and unequal blade
spacing. The tail rotor must produce thrust, both positive and negative, with the
air ...

Fundamentals of Aerospace Medicine
The tail rotor is mounted perpendicular to the axis of rotation for the main rotor
system. Just as with the main rotor, the tail rotor produces varying lift, or thrust,
depending on the pitch angle of the blades. Tail rotor thrust is varied through the
use ...

Operator's Manual: Army Model OH-58C Helicopter
Loss of Tail Rotor Effectiveness. a. Loss of tail rotor effectiveness (LTE) is the
occurrence of an uncommanded and rapid right yaw rate which does not subside
of its own accord and which, if not quickly reacted to, can result in loss of aircraft ...
