Helicopter main rotor blade injury to the head with survival.
Introduction Rotor blade lllJunes are uncommon in the Armed Forces because of continual safety training and protection in relation to the use of helicopters. Rarely, accidents do still happen as a reminder that even with acute awareness of ground movements, incidents will occur. A review of the total United States Army rotor blade accidents between 1972 and 1991 reported 24 strike injuries, 12 ...
متن کاملQuad - Rotor Unmanned Aerial Vehicle Helicopter Modelling & Control Regular Paper
This paper presents the investigation of the modelling and control of a quad‐rotor helicopter and forms part of research involving the development of an unmanned aerial vehicle (UAV) to be used in search and rescue applications. Quad‐rotor helicopters consist of two pairs of counter rotating rotors situated at the ends of a cross, symmetric about the centre of gra...
متن کاملHelicopter Rotor Unsteady Aerodynamics
Unsteady helicopter rotor aerodynamics are complicated. This paper reviews some of the fundamentals and newer developments of unsteady helicopter aerodynamics. Rotor flow is beautiful and complex. Visualizing rotor flow allows for an appreciation of the following theories and solution attempts as well as nature’s complexities. The flow through a helicopter rotor with forward motion is shown in ...
متن کاملEvaluation of Rotor Structural and Aerodynamic Loads Using Measured Blade Properties
The structural properties of Higher harmonic Aeroacoustic Rotor Test (HART I) blades have been measured using the original set of blades tested in the wind tunnel in 1994. A comprehensive rotor dynamics analysis is performed to address the effect of the measured blade properties on airloads, blade motions, and structural loads of the rotor. The measurements include bending and torsion stiffness...
متن کاملDistributed Measurement of Aerodynamic Loads
A method for accurately measuring the drag associated with a protuberance on an aircraft has been devised and implemented in a wind tunnel using a C-130 model. The C-130 aircraft has been heavily modified for various different configurations and the impact that these modifications have had on the aerodynamic performance of the aircraft has not been well documented. This paper describes a method...
