The present invention relates to a new type aircraft. The aircraft
includes the airframe and wing, characterized in that the transverse
section of airframe has an oblate (oval) profile with corrugated area on
the ventral of airframe; the aircraft has uneven friction areas on the
underside surface of wing; there are fireproof & anti-wear layers on the
envelopes of airframe ventral and friction areas; the said fireproof &
anti-wear layers have tire rubber material. When the aircraft is in
motion with high velocity, the friction with air is increased, which
produces bigger lift with more aircraft load and shortened takeoff &
landing distance of aircraft, meanwhile the safe peril to aircraft caused
by the shear transformation of wind in flight is prevented effectively;
the fireproof & anti-wear layers on the envelopes of airframe ventral and
friction areas have an effect on higher anti-wear proof and longer
aircraft life.
