Slowing the air to low supersonic speeds using a cone minimizes loss in total pressure (increases pressure recovery). Also, the cone, together with the inlet cowl lip, determine the area which regulates the flow entering the inlet. If the flow is more than that required by the engine then shock position instability(buzz) can occur. If less than that required then the pressure recovery is lower which reduces engine thrust.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>An inlet with cone may be used to supply high pressure air for ramjet equipment which would normally be shaft-driven on a turbine engine, eg to drive turbopumps for the fuel pump on the <a href="/wiki/Bristol_Thor" title="Bristol Thor">Bristol Thor</a> ramjet and hydraulic power on the <a href="/wiki/Bristol_Bloodhound" class="mw-redirect" title="Bristol Bloodhound">Bristol Bloodhound</a> missile. </p> <div class="mw-heading mw-heading2"><h2 id="Shape">Shape</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Inlet_cone&action=edit&section=2" title="Edit section: Shape"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The cone angle is chosen such that, at the design condition for the inlet (Mach 1.7 for the <a href="/wiki/English_Electric_Lightning" title="English Electric Lightning">English Electric Lightning</a> inlet<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>), the shock wave that forms on its apex coincides with the cowl lip. The inlet passes its maximum airflow and achieves its maximum pressure recovery.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> A higher design speed may require two oblique shocks focussed on the lip to maintain an acceptable pressure recovery and pass maximum airflow. In this case a biconic cone is required with two angles ( the <a href="/wiki/Bristol_Thor" title="Bristol Thor">Bristol Thor</a> ramjet has 24 and 31 degrees for a design speed of Mach 2.5).<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> For higher speeds a more smoothly contoured transition between cone angles may be used in what is known as an isentropic spike (<a href="/wiki/Marquardt_RJ43" title="Marquardt RJ43">Marquardt RJ43</a> ramjet).<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> </p><p>The conical body may be a complete cone centerbody in a round inlet (<a href="/wiki/MiG-21" class="mw-redirect" title="MiG-21">MiG-21</a>), a half cone in a side-fuselage inlet (<a href="/wiki/Lockheed_F-104_Starfighter" title="Lockheed F-104 Starfighter">Lockheed F-104 Starfighter</a>) or a quarter cone in a side-fuselage/underwing inlet (<a href="/wiki/General_Dynamics_F-111_Aardvark" title="General Dynamics F-111 Aardvark">General Dynamics F-111 Aardvark</a>). </p><p>The rear of the cone beyond its maximum diameter, rear-facing and unseen inside the duct, is shaped for a similar reason to the protruding front part. The visible cone is a supersonic diffuser with a requirement for low loss in total pressure, and the rear, streamlined part, together with the internal surface profile of the duct, forms the subsonic diffuser, also with a requirement for low loss in total pressure as the air slows to the compressor entry Mach number. </p><p>For Mach numbers below about 2.2 all the shock compression is done externally. For higher Mach numbers part of the supersonic diffusion has to take place inside the duct, known as external/internal or mixed compression. In this case the rear part of the forward-facing conical surface, together with the internal surface profile of the duct, continues the supersonic diffusion with reflected oblique shocks until the final normal shock. In the case of the <a href="/wiki/Lockheed_SR-71_Blackbird" title="Lockheed SR-71 Blackbird">Lockheed SR-71 Blackbird</a> with part of the supersonic compression taking place inside the ducting the spike and internal cowl surfaces were curved for gradual isentropic compression.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> The inlet cone also has different axial positions to control how the capture area varies with the duct internal throat area. For best intake operation this required area ratio gets bigger with increasing flight Mach number, hence the large inlet cone movement on the <a href="/wiki/SR-71" class="mw-redirect" title="SR-71">SR-71</a> which had to perform well from low speeds to Mach 3.2. On the SR-71 the cone moves back at higher speeds.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Operation">Operation</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Inlet_cone&action=edit&section=3" title="Edit section: Operation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>At subsonic flight speeds, the conical inlet operates much like a pitot intake or subsonic diffuser. However, as the vehicle goes supersonic a conical <a href="/wiki/Shock_wave" title="Shock wave">shock wave</a> appears, emanating from the cone apex. The flow area through the shock wave decreases and the air is compressed. As the flight Mach number increases, the conical shock wave becomes more oblique and eventually impinges on the intake lip. </p><p>For higher flight speeds a moving cone becomes necessary to allow the supersonic compression to occur more efficiently over a wider range of speeds. With increasing flight speed, in typical Oswatitsch-type supersonic moving-cone inlet - the cone is moved forward (MiG-21), and if it is non-Oswatitsch-type cone inlet (SR-71) it is moved to the rear, or into the intake. In both cases, due to the shape of the cone surface and the internal duct surface the internal flow area gets less as required to continue compressing the air supersonically. The compression occurring in this path is called "internal compression" (as opposed to the "external compression" on the cone). At the minimum flow area, or throat, a normal or plane shock occurs. The flow area then increases for subsonic compression, or diffusion, up to the engine face. </p><p>The position of the cone within the intake is usually controlled automatically to keep the plane shock wave correctly located just downstream of the throat. Certain circumstances can cause the shock wave to be expelled from the intake.

The ramp, which is separated from the fuselage by a diverter, produces an oblique shock in order to decelerate the flow. The leading edge of the splitter plate separating the two intakes is located downstream of this oblique shock.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup> </p><p>Many supersonic aircraft (<a href="/wiki/F-16_Fighting_Falcon" class="mw-redirect" title="F-16 Fighting Falcon">F-16 Fighting Falcon</a>) dispense with the conical centrebody and employ a simple <a href="/wiki/Pitot_tube" title="Pitot tube">pitot</a> intake. A detached, strong normal shock appears directly in front of the inlet at supersonic flight speeds, which leads to poor pressure recovery. </p><p>NASA has tested an alternative to the external/internal, or mixed compression inlet, needed for speeds above about Mach 2.2 (below that speed inlets with all-external compression are used). The mixed-compression inlet is susceptible to unstarts or expulsion of the internal shock to in front of the inlet. The NASA inlet, which they call a Parametric Inlet, does all the supersonic compression externally so there is no shock inside the ducting in a potentially unstable location.<a rel="nofollow"
