The present inventive subject matter relates to a method and apparatus for an airspace plane with supersonic double decker wings.
Blots represent an acronym for Busemann (biplane) leading edge slats. The Busemann (biplane) constitutes an historic isentropic (perfectly reversible) supersonic (double) wedge postulation whereby the incipient shockwave is being refracted between the two wedges and rexpanded to its original (supersonic) state in perfect harmony. Because of semblance to the (1935) BIPLANE state of the art, the Busemann hypothesis is modernly being perpetuated as a supersonic “Biplane” platform. By postulating the Blots as (micro) slots on the leading edge of a supersonic wing, shockwave formation may be suppressed in totality by reconfiguring the Blots as (1) diverging wedges (2) a throttling ramp (3) regenerative heat exchanger whereby the Blots will be transformed into a (powerful) Joule-Thomson refrigeration engine that enables isothermal compression of the incipient shock front that drives the (throttling) Joule-Thomson refrigeration engine conversely. However, because of the diverging Blots wedges, the incipient shock front is additionally pared/Switched into two conjunctively disjointed (diverging) supersonic potential fields enveloping the appurtenant wing/leading edge into a zero (Mach Number) stagnation wedge/depression/singularity.
Because (1) isothermal compression constitutes a singularity and (2) because isothermal compression defaults into a wildly gyrating (harmonic) process the Blots may consequently by development be transformed into (complex/imaginary) Carnot refrigeration engine whereby the wildly gyrating stagnation surges are being transformed in accordance with the Ideal Gas Law whereby T2/T1=(p2/p1)̂(k−1)/k which renders 10/20/30/40/50× (stochastic) stagnation pressure surges=1.9/2.4/2.6/2.9/3.1× (i.e. 66/83/90/100/107 C absolute temperature swings/surges @20% transformation efficacy in conformance with May/2011 “VT4” (Virginia Tech (cryogenic) shockwave piercing (regression) tests) that penetrates the ambient oxygen saturation zone regressively outside the cryogenic zone and hence develops into a full-blown Carnot (cryogenic) refrigeration engine.
In order to mitigate shockwave impediment with future supersonic platforms, A. Busemann invented the Busemann-Biplane postulation in 1935 whereby a leading shockwave is immediately expanded after formation within a wedged choke aperture. In accordance with the classical PRANDTL-MEYER theorem;
the Busemann-Biplane would recover 61.7% of the stagnation potential @Mach-2, however chilling the exit temperature marginally as a consequence of the two-step (Prandtl-Meyer) compression/expansion Busemann conformance.
The dynamics of Busemann leading edge slot as Mach 2/3/4 interceptor platform is being demonstrated as follows. In accordance with the laws of thermodynamics the work of compression wi=RT×ln(pr)=2.7×ln(2/3/4)=2.7×(0.89/1.1/1.39)=2.4/3.0/3.74 Btu/lb at Mach-3 @400R. Given hence a 12×½″ BLOTS aperture, the (BLOTS) mass flow=1×0.5× (1100×3)/100/12=0.1375 lb/sec @M3. The work of compression therefore=0.1375×RT/788×ln(10.3)=0.1375×27×2.33=8.7 Btu/sec. Given hence ⅛″ Aluminum nozzle liners, the regenerative BLOTS cooling power=A×k×ΔT/ΔL/3600=2/8/12×125×200/0.25/3600=0.58 Btu/sec. At ¼″ nozzle liners the regenerative (isothermal) cooling power=0.58×2=1.16 Btu/sec. At ½″ the regenerative cooling power=0.58×4=2.32 Btu/sec. Compare the isentropic work of expansion (k/(k−1))×RT×((pr)̂((k−1)/k)−1)=3.5×27×(10.8̂0.286−1)=92 Btu/lb/sec=12.7 Btu/sec @0.1375 lb/sec BLOTS mass flow.
The incipient/normal shockwaves are (1) being isothermally compressed and (2) re-expanded in a diverging/throttling aperture, real time BLOTS requires configuring the BLOTS aperture and heat conductive liners in conformance with the CARNOT sink and source heat exchange dynamics in accordance conductive flux Q=kA(Δt/Δx), where Q=isothermal work of compression, k=conductivity of the BLOTS liner, Δt=Joule-Thomson throttling potential and Δx=ΔL=thermal flux path length between inlet/compression and outlet/expansion/flashing apertures.

Which mainly combines concepts of thermodynamic sequencing, heat transfer dynamics, boundary layer separation, spatial adaptivity and Carnot (BLOTS/CLOTS) conformance.

An airspace plane with wings having thermally reactive leading edge slots is being described as the inventive subject matter. Whereby the slots are converging/diverging Busemann conforming wedges. In the case of the converging Busemann wedge the supersonic front is isothermally compressed. In addition to this in the case of the diverging Busemann wedge the supersonic front expands isentropically in the diverging section which brings about a supersonic cooling or chilling effect (the Carnot engine synthesis) on the Busemann wedge. This process further instills a isothermal compression of the supersonic flux as a condition of optimality leading to refrigerated chilling in turn leading to the cryogenic zone. As this happens a portion of the ambient oxygen is liquefacted in the converging Busemann aperture followed by the evaporation of the liquefacted oxygen in part or totality concurrent with isentropic expansion in the diverging Busemann aperture. The whole process of compression/liquefaction/flashing conforms as a Carnot refrigeration engine/cycle with the supersonic front the engine and liquefaction and flashing the upper and lower heat sinks, whereby isothermal compression, isentropic expansion and liquefaction/flashing of the supersonic front is limited to boundary layer in contact with the Busemann slots. And also, Carnot conformance may be predicated on the absolute temperature of the upper/lower heat sinks (i.e. isothermal compression and isentropic expansion) in lieu of the latent heat of condensation/evaporation of ambient oxygen;
Busemann shockwave piercing leading edge BLOTS/SLOTS, Carnot conformance is consequently imbedded into the master computational flight management gain algorithm as principal shockwave piercing and SSTO conformance denominator in lieu of simplistic stagnation pressure as the controlling dynamic condition of state. The Carnot cycle is imbedded in the stochastic optimal gain computation algorithm. Further the Carnot cycle is imbedded in a DP (Dynamic Programming) optimal (predictive) computational kernel in sync with the stochastic optimal gain computation algorithm as the condition of optimality. Whereby Carnot performance (in lieu of stagnation pressure in isolation) functions as is the controlling (Dynamic Programming) optimal predictive denominator. The propellant resource represents the cost/feasibility denominator in pursuit of Carnot optimality in the (Dynamic Programming) optimal predictive denominator. And also, the leading-edge slots are spatially configured as conical/circular converging/diverging Busemann conforming wedges.
In accordance with the elemental (isentropic) Busemann (“Bi-plane”) refractive shockwave compression/expansion postulation
Modernly however (instant) “BLOTS” art is best configured as a (supersonic) shockwave abatement (isentropic) leading edge slots. However because perfectly reversible (isentropic) expansion is in conflict with the 2nd Law of thermodynamics and because shockwave formation will nonetheless replicate on the leading edge of a (BLOTS) Busemann leading edge slats transformed (supersonic) wing, the BLOTS are, reconfigured into an asymmetric diverging refraction ramp (#2) that spawns Joule-Thomson (throttling) that turns the asymmetric diverging (BLOTS) refraction ramp into a powerful Joule-Thomson refrigeration engine.
However, because of the diverging BLOTS configuration the exit/leaving supersonic flux is paired/switched into two conjunctively independent (diverging) supersonic potential fields with a zero Mach/stagnation wedge/depression/singularity enveloping the appurtenant BLOTS (wing) leading edge.
By consequently configuring the asymmetric diverging (Joule Thomson) refraction ramp out of a super conductive material (copper/aluminum/graphite/nanocarbon), isothermal compression of the incipient shock front may be morphed into isothermal compression flux whereby the sub/super/hypersonic kinetic potential is being preserved by driving the Joule-Thomson throttling/expansion refrigeration synthesis.
As isothermal compression constitutes a singularity and the enabling BLOTS is a stochastic flux, it is necessary to reinstate the condition ante by switching the “wildly gyrating” stochastic flux back into the native isentropic domain via the instant (isentropic) flutes or splines or wedges switch facilitations. An airspace plane with wings having leading edge slots; the leading edge, slots further being; thermally reactive; and configured as double-decker wedges. The airspace plane wherein the slots are converging double-decker wedges. The airspace plane wherein the slots are diverging double-decker wedges. The airspace plane wherein the leading-edge slots functions/conforms as a Joule-Thompson refrigeration engine driven by the kinetic (stagnation) pressure front in the ambient zone. The airspace plane wherein the leading-edge slots conform as a Carnot refrigeration engine driven by isothermal compression within the cryogenic zone. The airspace plane wherein the Busemann leading edge slots are thermally (color selective) coated to augment black bulb radiation coupling between the incipient hypersonic front and the slots aperture. The airspace plane wherein the black bulb radiation coupling spawns/drives/facilitates/enables isothermal compression of the incipient hypersonic front by dissipation heat of compression spatially. The airspace plane wherein the Busemann leading edge slots defaults into a Carnot refrigeration engine upon contact of/with the isothermally compressed hypersonic front. The airspace plane wherein the Busemann leading edge slots acts as a hypersonic Boltzman black-bulb switch. The airspace plane wherein the slots acts as a hypersonic stochastic switch. The airspace plane wherein an exit aperture of the BLOTS Busemann hypersonic slots are fluted or grooved or splined.
