Multiple-Surrogate Approach to Helicopter Rotor Blade Vibration Reduction
The advantages of usingmultiple surrogates for approximation and reduction of helicopter vibration are studied. Multiple approximation methods, including a weighted-average approach, are considered so that pitfalls associated with only using a single best surrogate for the rotor blade vibration-reduction problem are avoided. A vibration objective function corresponding to a flight condition in ...
متن کاملApplication of a Weighted Average Surrogate Approach to Helicopter Rotor Blade Vibration Reduction
The advantages of employing multiple approximation methods and the effectiveness of weighted average surrogate modeling for approximation and reduction of helicopter vibrations is studied. Multiple surrogates, including the weighted average approach, are considered so that the need to identify the “best” approximation method for the rotor vibration reduction problem is eliminated. Various appro...
متن کاملSurrogate Based Optimization of Helicopter Rotor Blades for Vibration Reduction in Forward Flight
The effectiveness of surrogate modeling of helicopter vibrations, and the use of the surrogates for optimization of helicopter vibration are studied. The accuracies of kriging, radial basis function interpolation, and polynomial regression surrogates are compared. In addition, the surrogates for the vibratory hub shears and moments are used to generate an objective function which is employed in...
متن کاملHelicopter 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 کاملHelicopter Rotor Vibration Reliability Control Analysis
The benefits of applying multiple alternatives for mock-up and compression of helicopter harmonic motion are analyzed. Multiple mock-up approaches, along with a weighted-average mechanism, are approximated so that quicksand affiliated with only applying alone better alternate for the rotor blade vibration-reduction dilemma are bypassed. A harmonic motion external function matching to a flight c...
