Comparison of Rotor Structural Loads Calculated Using Comprehensive Analysis
Blade flap and chord bending and torsion moments are investigated for six rotors operating at transition and high speed: H-34 in flight and wind tunnel, SA 330 (research Puma), SA 349/2, UH-60A full-scale, and BO 105 model (HART-I). The measured data from flight and wind tunnel tests are compared with calculations obtained using the comprehensive analysis CAMRAD II. The calculations were made ...

تحقیق حاضر گزارشی است از تحلیل بخش مقدمه دو دسته از مقالات که عبارتند از: 11 مقاله از دو نویسنده دوزبانه فارسی زبان, که شامل مقدمه 4 مقاله به زبان انگلیسی و چاپ شده در مجلات بین المللی, مقدمه 3 مقاله به زبان انگلیسی و 4 مقاله به زبان فارسی چاپ شده در مجلات داخلی می شود؛ و 12 مقاله از محققان خارجی که در مجله applied linguistics به چاپ رسیده است. مبنای تئوری این تحلیل ها نظریه سوئلز (1990) یا هما...
15 صفحه اولEffects of torsion frequencies on rotor performance and structural loads with trailing edge flap
The effects of variation of blade torsion frequency on rotor performance and structural loads are investigated for a 1/rev active flap rotor and baseline rotor (no active control). The UH-60A four-bladed articulated main rotor is studied at a high-speed forward flight condition. The torsion frequencies are varied by modifying the spanwise torsional stiffness of the blade and/or the pitch link s...
