Shawn M Posted May 31, 2019 Share Posted May 31, 2019 whats the inlet "cover" on the lightning in a few of those pics? Lightning Run and Run2 to be specific looks to be blocked off but the heat plume from the engines say they're running Link to comment Share on other sites More sharing options...
TonyT Posted May 31, 2019 Author Share Posted May 31, 2019 (edited) When a Lightning is running at full chat you get shockwaves form in the intake and water vapour appears as the air is compressed, that is what you are looking at, similar to wing vortices, especially if it's a damp day as it was. You cannot have a jet engine running at supersonic speeds, it would disintergrate, so you design the intake to slow the airflow to subsonic speeds going into the engine, no matter what speed the actual jet may be doing. Some you will not see as it will be deep down the intake, but the Lightning you do. Neat effect huh ..

Out2gtcha Posted June 1, 2019 Share Posted June 1, 2019 Great pics! But I almost feel bad for these old birds..... Getting so close to the one thing they were built to do, but not ever actually getting there. LSP_K2 1 Link to comment Share on other sites More sharing options...

I meant more in their current state.........after doing what they do for so many years, only to get turned into jet dragsters effectively. I do suppose it is better this way than just sitting in a museum somewhere for the rest of their lives. Link to comment Share on other sites More sharing options...

TonyT Posted June 1, 2019 Author Share Posted June 1, 2019 The Sad part is the venom, it was airworthy as was the meteor, they were unable to find a buyer so they were ferried in then the airworthy engines removed and shipped to the USA as spares by the buyer of the others jets were for sale I believe.

TonyT Posted June 1, 2019 Author Share Posted June 1, 2019 18 hours ago, Jennings Heilig said: Actually it’s not compression that causes that, it’s a decrease in pressure. That’s suction in action. The compression happens much further down the intake. Those are some AWESOME pics!! Imagine if we had a taxiable F-111 or F-105?? Supersonic speeds also threatened inlet stability. The inlet's central shock cone served as a compression surface, diverting air into the annular inlet. As the Lightning accelerated through Mach 1, the shock cone generated an oblique shock positioned forward of the intake lip. Known as a subcritical inlet condition, this was stable, but produced inefficient spillage drag. Around the Design Mach speed, the oblique shock was positioned just forward of the inlet lip and efficiently compressed the air without spillage. When travelling beyond the Design Mach, the oblique shock would become supercritical, and supersonic airflow would enter the inlet duct, which could only handle subsonic air. In this condition, the engine generated drastically less thrust and may result in surges or compressor stalls, these could cause flameouts or damage.=leftThermal and structural limits were also present. Air is heated considerably when compressed by the passage of an aircraft at supersonic speeds. The airframe absorbs heat from the surrounding air, the inlet shock cone at the front of the aircraft becoming the hottest part. The shock cone was composed of fibreglass, necessary because the shock cone also served as a radar radome; a metal shock cone would interfere with the AI 23's radar emissions. The shock cone would be eventually weakened due to the fatigue caused by the thermal cycles involved in regularly performing high-speed flights. At 36,000 feet (11,000 m) and Mach 1.7 (1,815 km/h), the heating conditions on the shock cone would be similar to those at sea level and 650 knots (1,200 km/h) indicated airspeed,[nb 8] but if the speed was increased to Mach 2.0 (2,136 km/h) at 36,000 feet (11,000 m), the shock cone would be exposed to higher temperatures[nb 9] than those at Mach 1.7. The shock cone was strengthened on the later Lightning F.2A, F.3, F.6, and F.53 models, thus allowing routine operations at up to Mach 2.0.[85] Link to comment Share on other sites More sharing options...
DeanKB Posted June 1, 2019 Share Posted June 1, 2019 Reminds me of the Lightning tech who ran the aeroplane along the runway, on a slow speed run, to help diagnose a fault that only showed up when running. Yep - another fault end up with him taking off. He'd never flown a plane before, any plane. Amazingly, he was talked down & successfully landed on the runway. He needed new underwear.

Stevepd Posted June 2, 2019 Share Posted June 2, 2019 Went there years ago and took my Dad. I remember it like yesterday, you don’t forget an experience like that. Steve. Link to comment Share on other sites More sharing options...
