اصول پرواز: راهنمای نهایی نحوه عملکرد هواپیما
در حوزه هوانوردی، چهار نیروی اساسی در طول پرواز بر روی هواپیما عمل می کنند: لیفت، وزن، رانش و درگ. این نیروها باید هماهنگ باشند تا یک هواپیما بتواند با موفقیت ...
بدنه هواپیما
La <anchor>بدنه هواپیما</anchor>، یا بدنه هواپیما، برای جا دادن مسافران و محموله طراحی شده است و در عین حال به آیرودینامیک کلی وسیله نقلیه نیز کمک می کند. علاوه بر این، بخش دم که شامل تثبیت کننده های عمودی و افقی است، نقش مهمی در حفظ ثبات و تعادل در طول پرواز ایفا می کند.

**fuselage**, central portion of the body of an [airplane](https://www.britannica.com/technology/airplane), designed to [accommodate](https://www.britannica.com/dictionary/accommodate) the crew, passengers, and cargo. It varies greatly in design and size according to the function of the aircraft. In a jet [fighter](https://www.britannica.com/technology/fighter-aircraft) the fuselage consists of a cockpit large enough only for the controls and pilot, but in a jet airliner it includes a much larger cockpit as well as a cabin that has separate decks for passengers and cargo. The predominant types of fuselage structures are the [monocoque](https://www.britannica.com/technology/monocoque) ( _i.e.,_ kind of construction in which the outer skin bears a major part or all of the stresses) and semimonocoque. These structures provide better strength-to-weight ratios for the fuselage covering than the truss-type construction used in earlier planes.
