چکیده
طراحی وسایل نقلیه حمل‌ونقل هوایی شهری به دلیل ماهیت چندرشته‌ای و پیچیدگی‌های فنی، با چالش‌های فراوانی در فاز مفهومی و یکپارچه‌سازی زیرسیستم‌ها مواجه است. این پژوهش به‌منظور رفع این چالش، یک چارچوب طراحی سیستمی مبتنی بر مدل V را برای یک تاکسی هوایی بال‌ثابت ارائه می‌دهد. نوآوری اصلی این رویکرد در ایجاد یک فرآیند توسعه ساختاریافته است که از طریق اعتبارسنجی و صحه‌گذاری مداوم در هر مرحله، ردیابی کامل نیازمندی‌ها را تضمین کرده و ریسک عدم تطابق محصول نهایی با الزامات اولیه را تا ۴۰ درصد کاهش می‌دهد. این مدل با یک روش طراحی سنتی مقایسه شد؛ در روش سنتی، رشته‌های مهندسی نظیر آیرودینامیک و پیشرانش به صورت متوالی و با یکپارچگی محدود بهینه‌سازی می‌شوند. این رویکرد غیریکپارچه اغلب به دلیل نادیده گرفتن تقابل‌های کلیدی میان‌رشته‌ای، منجر به عملکردی پایین‌تر از حد بهینه در سطح کلان سامانه می‌گردد. نتایج عددی این مقایسه نشان می‌دهد که طراحی مبتنی بر مدل V به مداومت پروازی ۸۹ دقیقه (۵۶٪ بهبود)، برد ۹۵ کیلومتر (۵۵.۴٪ بهبود) و کاهش ۳۵.۶ درصدی در توان مصرفی کروز دست یافته است. علاوه بر این، این رویکرد منجر به کاهش ۸.۰ درصدی در وزن نهایی و صرفه‌جویی ۲۵.۹ درصدی در هزینه‌های ساخت گردید. این یافته‌ها اثربخشی مدل V را به عنوان یک چارچوب قدرتمند برای توسعه بهینه و قابل‌اتکای سامانه‌های هوایی پیچیده اثبات می‌کند.

چکیده English

The design of Urban Air Mobility (UAM) vehicles faces numerous challenges during the conceptual phase and subsystem integration due to their multidisciplinary nature and technical complexities. To address these challenges, this study presents a systems engineering framework based on the V-Model for a fixed-wing air taxi. The primary innovation of this approach lies in establishing a structured development process that ensures full Requirements Traceability Matrix (RTM) through continuous verification and validation at each stage, thereby reducing the risk of non-compliance with initial requirements by 40% .To evaluate efficacy, the performance of this model was compared against a traditional design method. In the traditional approach, engineering disciplines such as aerodynamics and propulsion are optimized sequentially with limited integration. This disjointed approach often leads to sub-optimal system-level performance due to the neglect of key interdisciplinary couplings. Numerical results from this comparison demonstrate that the design based on the V-Model achieved a flight endurance of 89 minutes (56% improvement), a range of 95 km (55.4% improvement), and a 35.6% reduction in cruise power consumption. Furthermore, this approach resulted in an 8.0% reduction in final weight and a 25.9% saving in manufacturing costs. These findings prove the effectiveness of the V-Model as a powerful framework for the optimal and reliable development of complex aerial systems.
