The proposed project would depend on the ability for the QE to be refitted with conventional launch and recovery of aircraft.  i though this could be a potential problem, but:

Quote:
No catapult or arresters will be fitted in the initial build but the carrier will be built to accommodate a future back-fit. The carrier will be fitted with a steam catapult or electromagnetic launch system and arrester gear, if the option to convert the carrier to the conventional take-off and landing (CTOL) variant proceeds.


http://www.naval-technology.com/projects/cvf/

so my scenario can proceed with an assumption that the JSF S/VTOL project fails to materialise due to the fact that the technology is unworkable.

After much debate on the carrier's future the QE refit is approved.  Given the rising global tensions and a resurgent Russian Nationalism under the self appointed President for life, (nicknamed Putin the Bootin' by a less than reputable tabloid) the refit is completed.

The Queen Elizabeth is to be equipped with navalised Typhoons.  The Admiralty is given back control of its air wing and initially reforms 800 and 801NAS of the new FAA.

Interesting idea with great potentials.
Do you have a general outline drawing you want to share with us?   Please?  


All the best from Jesper.

Have been trawling the net and have some basic drawings.  will try and concoct something when time allows.

was also thinking of a special squadron markings to celebrate the reformation of the FAA.  so will try and do some artwork as well if poss

the build itself will have to be more about fun than anything else.  I have realised with the Carrier and Harrier builds in GB's that doing a project that i want to get as right as possible doesn't go with getting the job done within the time frame- for me that is, as i always seem to work too slowly.

having said that- any technical suggestions would be welcome as i have very little knowledge of things like aerodynamics and avionics.

Someone (apologies for not remebering who) suggested moving the canards- and i can see why.  but would that affect airflow?  if i move the cockpit forward how will that affect COG.  i might try to do these regardless- as an exercise in kit bashing.  any thoughts are more than welcome please

I think it was 899 Squadron that gained an 'Omega' symbol on the tails of their Phantoms because they thought they would be the last fixed wing FAA Squadron? What about something involving an 'Alpha'? An alternative might be something evoking the pre-WW2 FAA markings like colourful fuselage stripes - Ark Royal's were broad 'blue/red/blue' with codes 'Letter/number/letter' where the first letter was the carrier (e.g. 'A' for Ark Royal), the number denoted that air group's squadrons (e.g. '6' for 800 Squadron) and the final letter was the individual aircraft code - usually (but not always) 'A' for the Squadron commander.

Guilty as charged, Your Honour. Airflow might not be such a problem as the a/c is already unstable and needs the avionics to make continual inputs to the canards to keep the aircraft doing what the pilot asks of it. However, Eurofighter went for the far-forward canards for manouevrability purposes. Closer coupled canards can be more efficient in cruise because of the biplane effect, but have a shorter lever so need to work harder - I'd suggest looking at the Rafale's canards and going for something like that. I think if the RN went for canards further back they would be sacrificing a little agility in return for slightly greater fuel efficiency and more importantly, ease of deck landing.

Cockpit forward - c/g issues perhaps, but may also make the a/c prohibitively long or not leave enough room for the radar, depending on whether you were going to put a 'plug' in the fuselage aft of the cockpit, or simply move the cockpit closer to the nose.

Partly correct XN!  It was 892- and for filial reasons would ressurect this squadron.  However, head has ruled the heart and thought it more likely to start with the 800's

Quote:

what is it they say about great minds?

hadn't thought about the inter war squadron markings but that is a good one.  was it 1938 when the FAA became a seperate entity from the RAF?  that would be perfect symmetry!

Haven't had a chance to see what the French navy Rafales are like in comparison to the standard versions, but will be checking them out.

good point too about the inbuilt instability- forgot about that.  i am even less familiar with the post cold war jets. so it is a learning experience.  i was thinking of possibly raising the cockpit, as they did with the FRS1, or a plug rear of the canopy to clear the forward view.  not sure if that would be clever though for all sorts of maritime reasons- storage and handling on to lifts for instance.  though the QE is big, it still could be an issue.

Noticed the Tornado has an arrestor hook, but it looks a spindly affair, so i might nick one from a Phantom.  the front leg might get a toom like extension.  the other thing is the radar the tiffie has- would the navy need a different one like the blue vixen, or is the capability of the existing equipment sufficient.  haven't had chance to check it out but i presume it will be okay.

Existing radar should be OK - difference between SHARs and 'Crab' Harriers in that respect was more to do with the fact that SHARs had an air to air role while the RAF's Harriers were largely A to G so did not need the scanning radar - GR.3 pilots were trained in air-to-air but mainly with guns and WVR Sidewinders. The Tiffie's A to A equipment would be easily enough for the RN.

A raised cockpit is an interesting idea though. Should be all, assuming their Lordships don't want the Sea Typhoon to be able to carry an 18in MkXXXI torpedo and a 12in MkX 45 calibre naval rifle as well as eight different types of radio and a mini-bar for the Admiral...

By Nelson's bowels i knew there was something else DOH!

Actaully- better not do that - don't wish to convert to a Barracuda

thanks XN- i rather suspected that the Thphoon's air to air capability should be sufficient, but wasn't 100% sure- appreciate the clarification.  not very well educated in modern ordinance - far too many acrynyms- can never remember what they all stand for.

i'd be all right as fighter pilot.  by the time i'd figured which acrynym to fire off it would be too late Angel

The Department of Health has requirements too?? Blimey, talk about the nanny state.

A misunderstood and maligned aircraft IMHO! And don't forget the real reason for moving the canards - left as they are there would be no way for the pilot to spot the fall of shot during a gunnery battle.

Hi XN

Quote:

yes- i was referring to the constant requirement ammendments and radios you alluded to- that continually added to the weight, which seems to have impeded performance.

Quote:

that would be a really cool way of arriving at the casualty department!

I did forget about the spotter role- do you reckon floats are in order? Think

Definitely, to be provided as a kit by the manufacturer for addition as well as catapult points to allow the aircraft to be launched from the midships position on light cruisers.

Provision for a four-gun turret will be looked upon favourably, and an ashtray on the control column.

(BTW take your point on the Barra indeed - Aeroplane has a Database on the poor old beast which I wrote for them nearly a year ago and still has not seen the light of day. Oh well...  )

bashed up a quick concept of what changes might take place



comments suggestions welcome

thank you for your support thus far and in anticipation of its continuance

Have made some in-roads but progress has been sporadic.  not taken any pics though as when do get to work i just want to crack on with it

will try and post some pics later this week.

the upper cockpit has been chopped.  wings sliced for folds.  cockpit painted. panel lines removed and recribed
considering where to stick the arrestor hook- (now, now-steady. i know what you are all thinking) want to try and get the cockpit stuck onto the fuselage, but the airbrake could be tricky so having a think about it.

have made a bit of progress

Quick word on the kit.  it seems to be the evaluation aircraft. detail is sparse both externally and internally.  the cannon and refuel probe need to be scratch built.  not all panel lines are present but might let that pass as some are in tricky places.   yet to improve the seat as might use pilot- which seems well done compared to earlier figures and has a near enough representation of the helmet.

the sensor on the starboard side by the cockpit is a PIRATE which helps the landing amongst other things.  this renders all my mods as superfluous - but i would argue that clear forward vision without electronic aids is still critical for carrier based oprations in case of system failure or battle damage to the PIRATE






but not sure if the cockpit should have been raised a tad more, but i wanted the radome to fit smoothly without having to radically alter the profile or the length.  got away with an overhang of 6" that needed to be filled.

also might reconsider the position of the canards.

edit:please feel free to contribute thoughts- would be much appreciated

Looking forward to seeing this built Walrus.

I remember reading a few years ago a Parlimentry Report where they debated on - what were the armed forces going to do if the JSF was cancelled, did not perform to spec, or if software access was not released for the computers on board thus giving the aircraft limited capabilities. This was also at the time the Sea Lords were determining the design of the Queen Elizabeth class - CTOL or STOVL.

BAe proposed a sea borne variant of the Typhoon but it was politely turned down as the re design costs and limited production run of around 60 would not be cost effective and could not be afforded.  The back up aircraft was decided to be the Rafale or the F-18E/F. Single or twin were not determined at that time.

The French were hoping to use the wining ship design (If CTOL) for their second carrier build as they could not afford another nuclear Charles D Gaulle which is why the Rafale was selected. It would also save on carrier quals etc if both countries had the same basic carrier.

I think the Rafale is still the back up if the F-35B ends up been a flying brick.
The RAF would get Tranche 3 Typhoons as replacementfor their F-35Bs.

Thanks for that Thomas

in discussions with my brother on this issue, the naval version of the Rafale was mentioned.   it would make more sense as the type is proven so development costs would be a much smaller amount to convert to FAA standards if that was necessary.
i think that should have been the course of action to take as the technical problems of the vtol jsf are yet to be resolved.  also there is the question of software.  the US companies to my knowledge are reluctant to see the fruits of their labour go abroad.  i stand to be corrected on these issues. but a tie in with the French would make more sense in my opinion.

Interesting project Walrus, and some superb work so far.

Still would not surprise me if, budget issues notwithstanding, Sea Typhoons were on the agenda somewhere. Politically, going with Rafale might prove a bridge too far - both in terms of our perceived relationship with the US, and bearing in mind that BAE was going to get quite a lot of work out of it. If Rafale/Hornet was the option I can see BAE getting some fairly sizeable modification/refurb contracts by way of consolation. Could be the Phantoms all over again!

Another way to make the 'what-if' more realistic might be if the aircraft was a demonstrator for BAE pitching for export sales in competition with Rafale and Super Hornet. Bit late now, but hey.
