| چکیده | ||
| تونل باد یکی از پرکاربردترین تجهیزات در زمینه طراحی وسایل پرنده است که به کمک آن رفتار آیرودینامیکی و قدرت سطوح کنترلی یک وسیله پرنده پیش از پرواز مورد بررسی قرار‌می‌گیرد. از طرفی یکی از ضروری‌ترین بخش‌های تونل باد، واحد زاویه‌سنج بالانس آن است که به وسیله آن تنظیم زاویه مدل و قرائت دقیق آن در هنگام تست تونل باد در هر لحظه با دقت بالا انجام می‌شود. طراحی واحد زاویه‌سنج در بالانس تونل باد، ملاحظات متعددی را در مرحله انتخاب، نصب و راه‌اندازی می‌طلبد. این اقدامات ضروری به منظور کاهش خطای اندازه‌گیری و در نتیجه قابل قبول بودن نتایج تست‌های عملی انجام می‌پذیرد. در این مقاله به بررسی و تحلیل پارامترهای مهم در طراحی بهینه زاویه‌سنج بالانس تونل باد پرداخته خواهد شد. در ابتدا پارامترهای موثر و روش‌های کالیبراسیون بیان و سپس چیدمانهای متعدد نصب و استفاده از واحد زاویه‌سنج بالانس بررسی و روش بهینه طراحی چیدمان برای آن در تونل باد انتخاب خواهد شد. | ||

| چکیده [English] | ||
| The wind tunnel is one of the most widely used equipment in the design of flight vehicles to investigate the control surface effectiveness and also, aerodynamic pre-flight behavior of these vehicles. On the other hand, one of the most essential parts of the wind tunnel is the balance tilt measurement unit, which measures the attitude of the balance and installed model with high accuracy. There are several ways to design the tilt measurement unit of wind tunnel balance. One of them is to use proper and efficient accelerometers by considering selection, and optimal installation of them in the tilt measurement unit of wind tunnel balance. These Considerations are necessary to reduce the measuring error and make the test results reliable. In this paper, firstly, the effective parameters and calibration methods will be presented. Then, several arrangement methods for installation of these accelerometers will be presented and finally, the optimal design method will be proposed. | ||
