The invention discloses an ultra-light type competitive titanium alloy parawing aircraft which comprises a vertical beam. The middle of the vertical beam is fixedly connected with a propeller protection frame; the propeller protection frame is connected to the vertical beam through protection frame supporting rods in a multi-point mode; the bottom end of the vertical beam is connected with a mainbeam through a vertical beam connector; the main beam is perpendicular to the vertical beam; an engine mounting base is arranged in the middle of the vertical beam; a hanging bracket buckle is arranged above the engine mounting base on the vertical beam; the hanging bracket buckle is movably connected with one end of a main hanging bracket matched with the hanging bracket buckle; the other end ofthe main hanging bracket is connected to the main beam through a hanging bracket fixed spindle; an undercarriage is arranged at one end of the main beam close to the propeller protection frame; a rearwheel is arranged at the tail end of the undercarriage; the other end of the main beam is fixedly connected with one end of a head pipe; the other end of the head pipe is connected with the middle ofa front fork; and the front fork is connected with a front wheel. Starting from the aspects of the vertical beam, the propeller protection frame, the undercarriage, the main hanging bracket, the front fork and the like, on the basis of ensuring safety, the parawing aircraft is higher in portability and lighter in dead weight, and flight enthusiasts can conveniently take part in flight movement ofthe parawing aircraft at a lower threshold.
