The invention belongs to the technical field of aircraft design, and relates to an asymmetrically-arranged turboprop aircraft exhaust pipe layout which comprises a fuselage, a left exhaust pipe and a right exhaust pipe are arranged on the two sides of the fuselage, and the exhaust directions of the left exhaust pipe and the right exhaust pipe deflect backwards by a certain angle in the heading direction. The left exhaust pipe and the right exhaust pipe are asymmetrically arranged according to the rotating direction characteristics of the propellers, outlets of the left exhaust pipe and the right exhaust pipe are beveled by a certain angle, through the design of deflecting backwards by a certain angle, waste gas generated by an engine is exhausted out of an aircraft, and part of residual thrust can be recycled; the left exhaust pipe and the right exhaust pipe are asymmetrically arranged in a deflection mode according to the rotating direction characteristics of the propellers to balance part of reaction torque of the propellers. The performance of a turboprop engine and the use safety of a turboprop aircraft are guaranteed, the control design performance of the aircraft can also be improved, the method can be used in the design of similar turboprop aircraft exhaust pipes, and an outlet is beveled by a certain angle to reduce the weight of the aircraft.
本发明属于飞机设计技术领域,涉及一种非对称布置涡桨飞机排气管布局,包括机身,所述的机身两侧设置有左右两个排气管,所述左右两个排气管的排气方向沿航向向后偏转一定角度,左右两个排气管根据螺旋桨旋转方向特征非对称布置,所述左右两个排气管出口斜切一定角度,本发明通过向后偏转一定角度的设计,将发动机产生的废气排出飞机,又能回收一部分剩余推力;通过根据螺旋桨旋转方向特征,非对称偏转设置左右排气管,用以平衡部分螺旋桨反扭矩。即保证涡桨发动机的性能和涡桨飞机的使用安全,亦可提高飞机操纵设计性能,可用于类似涡桨飞机排气管的设计中,出口斜切一定角度用于减轻飞机重量。
