This is aooomplished. in the tollowine mannor:- An airor a.rt \71th a body whioh my be of circular shape but the bo~ as a whole io of a shApe capable of ganeratin8 aerodynamic lift. Located.in nnd oonoontrio with an annular BaP in and around the top of the a.irorni't i s an annular aerofoil of a section which gives a l aadiD5 edte around the inner oiroumfcrenoe and a traili.DJ cdgo around t he outer oiroum.ferenoe of tho annular aerofoil. The upper aurfaoe of the annular a.er ofoil i s exposed to the ambi ent atmosphere and tho lo~or ourfaoe f nooa do rda into the body of tho airora.i't. The annulnr gap between tho trailing edBo of the annular a.erofoil and the outer oiraumferenoe of the cavity in which tho annular aerofoil is looo.t ed i s oapablo of beinc olooed or being vo.riod in size equnl~ or unequo.lly around tho a.nnula.r gap by selective and controlled movement of suitable vnnoo or shutters. A similar provision ~ be made !or the annular gap between the leading edge of the annular eerofoil o.nd the inn or oi roumferonoe of tho oo.vi ty in which the nnnula.r aerofoil io located. The annular aerofoil is attached to a or parti al disc located within the aircraft and below, ooncentrio ond parallel with the annular acrofoil. Tho annu.l.a.r aor ofoil ~ be c upablo of oontrollod porpandioular movement relative to t he dioo or partial diao. An annular chamber with a oontinuouo lipped aap a round oaoh of the inner and outer circumferences of the chamber io located within the body of the aircraft and conoentrio lvith the annular aerooil. The lips of t he gap around the outer oiroumforenoe o! tho chamber faoe the l eading edge of tho annular a orofoil. Thie chamber nnd tho lipped gnpa around its inner and outer oircumferenooa are respective~ and hereinafter referred to no the inner throat, the inlet o the inner throat and the outlot of tho inner throat. A similar ohnmber but of larger inner u.m outor oircumferonoes is looa t od within the body of tho aircra.ft and oonoentrio with the mmular aorofoil. Tho lips o! the eap around the inner circu;'ll'orcnce of tho chanbor r".co tho trail:ing cdce of the W'Ulular uol.'oi'oil. This chamber o.nd the lipped e;.lpEl around ito inner and outor ciroucfercnces aro roopoc~ivo~ d hereinafter rofcrrcd to 1.e tho outer throat, tho inlet of tho outer throat nnd tho outlet of the o~tor throat. Tho inner and outor thron.to rn.:J3 bo capable of cont 1left pe~ndicular and/or tiltin~ covcncnt relative to tho plano of tho a.nnular acrofoil. Located in or ncar the outer th1oat are vertic~ und horizontal vanoo or blades c blo of selective and controlled rotating movcoont. The inner throo.t and/ or tho out or throo.t mAY bo attached to the body of the ai1.-cro.ft or to the dioo o::-partial disc. The disc or partial disc hno a centra l vertica l nxlo \lhich io mounted in boarinBS attached to tho aircraft. An air eenerator or gcner3.toro \':'hich may be in tho fo=m of a fan or fans io or aro alec attnchod to the vortioal axle. Tho disc or partinl dioc ~ have f blade~ attached around and ncar ito outer oirow:d'cronce. Tho diac or pa=tial. dioo and a.ttao.'uncnts a.ro rotated by jot reaction dovioco utto.chod to end noo.r tho outer circumforcnco of tho disc or pa io.l disc. Tho inlets of the jet reaction devices are connected to an ~ular chamber located within tho body of tho aircraft and concentric \71th the disc or po.rtial disc and tho offlux outlets of the jet :roo.ction devices ara connooted to a eimilar chamber. Tho ohumber to which the offlux outloto or the jet rodotion dcviooo aro oonneotod baa outlets or an outlet around the body of tho aircraft and open to the ambient atmosphere. Tho outlote or outlot of tho chambor aro capable of being varied in sizo oquc.lly or unequally by ooloctiva and controlled movement of suitable vo.nea or shutters. Vorticnl o.nd horizontal vanes or blades co.pnblo of selective nnd controlled rotating movement ~ bo located acroao tho outleta or outlot of tho chamber. The production of aer c lift by the invention for vortica.i flic;ht is accomplished in tho following mannor:- A l o.rco voluno of ui~ is e-enora.ted by the crir ..,one~a.tor or eonaratore, i!?-forced through tho inlet of tho inner throa.t, throu;:;h the inner throo.t, and throne.~ ond shaped by the outlet of t!:lo i:-.ner thro~t, :I.J:lpin.::'es on and i s di vidod by the l9o.d~ odco of tho rumulur o.orofoil, r ..... cooo ovor and ur.der the annula r nerofoil and c:...uses the :...."1:.-u.J.o.r a.vrofoil to .1roduce ecro~e lift. The o.c1ount of o.erodyna.r.ic lift procuced by tho annular aerofoil is regulated by vo.r.y~ tho outv~t of tho air eonerntor and/or by vnxy~ tho pooition o.round the leading adee of tho aorofoil .. t which tho cain mss of o.ir ir.pi:tsoa by controlled vertica l movement of tho or thro~t d/or tho annular o.orofoil. After po.ooine ovor nnd under tl1o annular aerofoil the ui.r is forced and suclccd into the ir.lct of too outer throat a rod thio co~.bined. 'l'1i th rotation of the e..nnular acrofoil rosul te in a dceroo of boundD.ry lo.yor control of the air flo'll' over the annulnr uerofoil. The air is thon forced and sucked thro~h tho outer thro:\t, nnd through tho outlot of the outer throat into the annular chor:lhor in which the inlets of tho jot ronction devices aro locntod. Tho paoseee of the nir into tho rumular chamber r:JD.y bo assisted by tho action of the ft.n blades l1hich roy be att~od around and ncar the outor oircumferenco of tho disc or partial disc. production of aoro~amio lift by the invention for transitional fli~t is uccom,liahed in tho follov~ ~or:- ~:Ovox:ont of the aircrai't in tho horizontal. plana rolutivo to the plane of tho nircruft or in a. plane nith a aubotu.ntinl horizonta l component relative to the plane of tho D.iror .ft C(l.uooo the boey of tho nircraft to produce c.crodynnmio lift Jtd a t and above a certnin speed of oovcmcnt in such planes the body produces sufficient uoro~o lift to sustain flieht.
