The invention belongs to an aircraft design technology and relates to an aircraft layout aircraft considering transonic and supersonic aerodynamic performance. The aircraft body head is in a slender tip shape, medium sweepback trapezoidal wings are adopted as the wings, full-motion horizontal tails are symmetrically installed on the two sides of the rear end of the aircraft body, a large sweepbackvertical fin is installed above the rear end of the aircraft body, a rudder is installed at the rear end of the vertical fin, engine air inlet channels of the aircraft are located on the two sides ofthe middle-front portion of the aircraft body, and an engine cabin of the aircraft is located at the rear of the fuselage; the slenderness ratio of the fuselage is 8-11, the sweepback angle of the leading edge of each wing is 35 degrees to 45 degrees, the sweepback angle of the leading edge of the horizontal tail is 35 degrees to 45 degrees, and the sweepback angle of the leading edge of the vertical tail is 50 degrees to 60 degrees. According to the aircraft aerodynamic layout disclosed by the invention, on the basis of ensuring controllability of the subsonic velocity of the aircraft, lift-drag ratio maximization of the transonic velocity and the supersonic velocity is realized, and stable control from the subsonic velocity to the supersonic transverse course can also be met.

    本发明属于飞行器设计技术,涉及一种兼顾跨、超声速气动性能的飞行器布局飞机。所述机身头部为细长尖头状,机翼采用中等后掠角梯形机翼,机身后端两侧对称安装全动平尾,机身后端上方安装一个大后掠垂尾,垂尾后端安装方向舵,飞机的发动机进气道位于机身中前部两侧,飞机的发动机舱位于机身尾部;其中机身长细比为8‑11,机翼前缘后掠角为35°‑45°,平尾的前缘后掠角为35°‑45°,垂尾的前缘后掠角为50°‑60°。本发明所公开的飞机气动布局在保证飞机亚声速可控性基础上,实现了跨声速和超声速的升阻比最大化,还能够满足从亚声速到超声速横航向的稳定控制。
