This is a normal post and what's going on here

This is a normal post they lost a packet on swapping back from a catapult launch/arrestor hook with no VTOL
to one that does ski jump/vertical land because the non-nuclear aircraft carriers we have couldn't provide the steam for the launch. If I recall correctly.

This is a normal post I mean why are we buying yank planes instead of Eurofighters

This is a normal post BAE Systems build something like 20% of the plane
And it'll be cheaper than trying to convert the Typhoon (which we build about 25% of) to carrier use.

This is a normal post Carriers, innit.
Our non-nuclear carriers can't generate the steam force to launch the Typhoon, the typhoon airframe wouldn't like the stresses of arresting without modification and its limited air/ground attack capability make it pointless for the role. And it's not stealthy.

This is a normal post For the cost of a navalised Typhoon
You could probably buy two or three Rafales. That'd be a hard sell.

This is a normal post It's nice to see Dassault finally stop
turning out new versions of the Mirage. Take Heed, Porsche. Stop making 911s.

This is a normal post In order to get the Typhoon to fly from a carrier...
...BAe would have to fit new undercarriage, reinforced folding wings, more powerful engines and flight controls, an arrestor hook complete with strengthened mounts, not to mention the necessary strengthened structure.

The end result would be heavier, more expensive and have less range than a carrier plane designed as such from the outset like an F-18 or Rafale. The Royal Navy has looked at buying Rafales, which could well be an option if the US decide to can the STOVL version of the F-35.

This is a normal post I forgot about the folding wings requirement.
well done sir.

This is a normal post The powerplant of the QE carriers....
...is four gas turbine engines, with what is in effect a dynamo to supply electric power to the engines directly instead of the old fashioned system of boilers and turbines, which used to supply the steam needed for catapults. Moreover, the torque of a steam catapult cannot be adjusted, so they cannot launch very light UAVs, hence the need for modern carriers to be fitted with a sci-fi railgun. BAe managed to accidentally "inflate" the cost of adapting the QE carrier for a railgun, just in case the MoD decided that the F-35 is too expensive to procure and went down the route of buying F-18s or Rafales instead. Remember that BAe and Rolls Royce have a lot at stake if the F-35 turns out to be a massive white elephant.

This is a normal post that reminds me of the time when Jaguar were taken over by Ford
in the design of the next XJ the engine bay monocoque was deliberately made too narrow for Ford to buy in Rover 60 degree V8s (and becoming common) so their engine choice became a home-designed 90-degree vee after the straight-sixers.

This is a normal post I read this story too...
...there are parallels with Triumph designing their own V8 for the Stag, rather than installing Rover V8s too.

This is a normal post two straight fours on a common crank
the term 'notoriously weak' is often used, which is a shame. Then again, did not Daimler refer to their V12s as a 'Double 6'?

This is a normal post Two straight fours on a common crank...
...pretty much sums up the Audi V8's origins - basically two Golf GTi 16v units spliced together. It's not an unusual arrangement.

This is a normal post I understand there are some problems with compression
because at any one time you have a single combustion chamber trying to pressurise two other cylinders at various states of compression. But heck, I'm Diagnostics, that's for the people in Calibration or base engine design.
