专利汇可以提供Aircraft having vertical and forward motion aerodynamics专利检索，专利查询，专利分析的服务。并且The disclosure sets forth a winged aircraft having both vertical and forward direction aerodynamic capabilities which are both functional in the transition stage during landing and takeoff maneuvers.，下面是Aircraft having vertical and forward motion aerodynamics专利的具体信息内容。
1. A high forward speed vertically moveable winged aircraft having coincident centers of lift, gravity and vertical thrust and comprising: a fuselage structure; with inboard engines for generating horizontal and vertical thrust gases; dust structure communicating vertical thrust gases outboard of said fuselage a gas-directing slot structure extending from said duct structure longitudinally outboard on each side of said fuselage and directing thrust gases inwardly toward undersurfaces of the fuselage to join longitudinally therebeneath in a downwardly directed thrust stream having a coincident center of vertical thrust; a wing structure of predetermined configuration about said sLot structure and a forward extension on said wing structure extending about said slot structure and advancing both the slot structure and the center of lift of the wing to coincide with the center of gravity and vertical thrust, said forward extension and slot structure being aerodynamically compatible with said wing in a transition stage of flight during takeoff and during landing; and valve elements in the upper and lower surfaces of said wing adjacent said fuselage for the induction of secondary air through said upper surfaces of said wing and in the region of said slot structure therein and openable to induct turbulence generated by said forward wing extension during transition flight conditions between vertical thrust lift and aerodynamic lift.
2. The aircraft of claim 1 in which the inboard engines are located remote from the center of gravity of the aircraft a distance maintaining the location of the center of gravity.
3. The aircraft of claim 1 in which the said gas-directing slot structure is defined by a dual plenum in the form of a longitudinally slotted tube having a dividing wall extending through the slot thereof to divide the latter into two slots each in communication with separate and discrete longitudinally extending plenum portions of said tube; and a separate inboard engine serving each said plenum portions and connected thereto by separate duct structure.
