In an imperial tonne it is 38600 lb’s, but in a metric ton, it is 35000 lb’s. So a bit of ambiguity. Each EJ-200 ENGINE produces 20,200 lb’s of thrust (pretty approx at the moment ignoring tempertaure etc..) If using 38600 lb for take of weight 1.05 T/W is the case, but 35000 lb net takeoff weight gives T/W weight of 1.15.
I don’t agree with your figures.
I was calculating this assuming he meant metric tonnes i.e. 17.5 tonnes = 17,500kg or 38,600lbs.
If he meant imperial tons then 17.5 ton = 17,780kg or 39,200lbs, giving a T/W = 1.03
Hopefully he meant metric tonnes!
The 35,000lbs (15.6 tonnes) net takeoff weight you refer to is close to the one quoted on various sources e.g. wikipedia. Why do these figures not correspond to the pilots?
What the h…?!
“Five and a half ton´s of fuel”…
From the pilot.5,5 ton´s of INTERNAL fuel?! In a Typhonn?!
That´s half a ton more than expected :confused:
I found his figures interesting too, they seems to be painting a different picture to the official figures.
The loaded weight (full internal fuel with 2 ASRAAMs) quoted by the pilot is 17.5 tonnes or 38,600 lbs. This gives a ptw of only 1.05. This may explain why the pilot considered completing the loop in high temperture as ‘a tricky manoeuvre’.
Are there any plans to convert tranche 1 Typhoons to tranche 2’s?
On another board, Low Observable observed that:
[I]Typhoon is the aircraft the RAF needs now, and a three-tranche buy of 232 aircraft is the right number. (232 aircraft supports a 137 aircraft in service fleet, comprising seven squadrons, an OCU and an OEU).
The third Tranche is almost certainly going to replace the GR4, if it happens, since the perception now is that we no longer need seven Typhoon squadrons to replace three squadrons of Jaguars and six squadrons of F3s, despite the stream of ‘Bears’ testing the UK’s air defences and the obvious relevance of a deployable flexible offensive support aircraft.
It wouldn’t suprise me either if 2 squadrons of Typhoons replaced 8 squadrons of Tornados! Is this really likely though?
[QUOTE=eagle;1161314]Because those aircraft have dedicated stations for targeting pods.
You cant mount weapons or fuel tanks there.
Seems like a better design to have an additional pylon dedicated to targeting pods. Was this ever consider for the Typhoon?
[I]
3) No-one is going to “fight like hell to get the LDP moved from the centre station” because they don’t want it somewhere else, it’s in the right place now.
If the centre pylon is the right place why is it not used by other aircraft such as the F15E, Grippen or Rafale?
RAF pilots aren’t privy to that sort of information, much as they might like to be, so his story is worth no more than any other rumour. And no, it wouldn’t count towards the UK commitment.
Then how did he know the details of the Saudi deal before it was released? Why do you believe that it wouldn’t count towards the UK commitment?
Just how many bombs are usually required for a mission?, its seems to be over the top to have that many bombs!!
and heres another tidbit the UK MoD are trying to reduce the typhoon tranche 3 order..!
I spoke to an RAF Typhoon pilot of 3 sqn in April 2006. He told me, before the Saudi deal had been publicly revealed, that the Saudis would be getting 72 Typhoons and the RAF 160, which equates to the full UK commitment of 232 aircraft. As the Saudi deal is a government to government deal this surely will count towards the UKs commitment.
Stability, in this case, refers to the mounting.
Mount an LDP on a stub in the MRAAM recess and you don’t have a very rigid mounting (kind of important with an LDP….) just as you can’t put one underwing because the wing bends so much.
The centreline allows a very rigid mounting and a simple installation and integration.
But the original intention was for the pod to be used on a MRAAM pylon. What was the cause of this change?
The ability to carry fuel on the centreline pylon would only be ‘precious’ if the operators judged that carrying three tanks was necessary to meet their requirements. They don’t.
On the other hand, using the centreline mounting for Litening means that:
You don’t sacrifice an MRAAM
You don’t have to rejig the MRAAM launch sequence
You have a better FoV for the pod
Airframe masking algorithms are simpler
I read somewhere that suggested that the centreline was choosen as the the MRAAM positions were found not to be stable enough. If this is true it would suggest that the flight control software has been more challenging than expected. Any thoughts?
Typhoon has flown with Litening in 2006. LRF is a function of the pod, but I don’t expect it will be useful for AA, at least not for the austere AG capabilities.
Are there are any photos of the Typhoon with Litening? I’ve not seen any.
Is it using the centre pylon? There was talk originally of it using a fuselage missle pylon, but apparently this was not considered a stable enough position.
Not really..Pirate wont provide range unless it has a LRF that can range out to 100 nm.
You need all three, height, angular info and range for a proper weapons fix.
Could Litening provide a LRF function? If so, do the RAF intend to use it with Pirate as an alternative to the radar?
Has a Typhoon flown with a Litening pod yet?
