UK’S PIONEERING COMBAT AIR FLYING DEMONSTRATOR REVEALED

Industry partners, BAE Systems, Rolls-Royce and MBDA UK, together with the Ministry of Defence, have revealed the design of the UK’s flagship Combat Air Flying Demonstrator, as the aircraft reaches a major milestone, with two thirds of its structural weight now in manufacturing.

The piloted supersonic aircraft – the first of its kind to be developed in the UK in 40 years - is set to fly within three years. The aircraft’s main structure, wings and tail fins are all taking shape using pioneering robotic and digital manufacturing and assembly technologies at BAE Systems’ sites in Lancashire, signifying the advanced stages of its development.

Designed to test a wide range of new technologies, including the integration of stealth compatible features, the Combat Air Flying Demonstrator is a crucial part of the work to develop manufacturing processes and de-risk the next generation combat aircraft that will be delivered through the Global Combat Air Programme with the UK, Italy and Japan.

Tony Godbold, Future Combat Air Systems Delivery Director, BAE Systems, said:

“This significant and challenging project will deliver the UK’s first crewed combat demonstrator aircraft in four decades. The programme is accelerating the development of advanced design approaches and manufacturing techniques, helping to sharpen the UK’s industrial edge and deliver benefits beyond the production of the aircraft.

“As well as developing a unique aircraft, we’re building the technical foundations, workforce readiness and digital maturity essential to deliver the next generation of combat air capability.”

Richard Berthon, Director Future Combat Air, UK Ministry of Defence, said:

“I am delighted that today, BAE Systems and the Ministry of Defence, can share this important update on the Combat Air Flying Demonstrator. For the first time, people can see how this cutting-edge demonstrator aircraft will look when it takes to the skies. Manufacturing of the aircraft continues at pace, which is testament to the ingenuity and collaboration of Government and industry teams.

“The Combat Air Flying Demonstrator is providing invaluable lessons on future combat air delivery and equipping our people with the skills they will need to deliver GCAP.”

By applying advanced new solutions and digital manufacturing technologies, such as 3D printing, cobotics, digital twins, model-based systems engineering and virtual simulation, BAE Systems engineers are at the forefront of the revolution in aircraft design and manufacture.

Test pilots from BAE Systems, Rolls-Royce and the Royal Air Force (RAF) have now flown more than 300 hours of the Combat Air Flying Demonstrator in a bespoke simulator. Using simulated flight trials, pilots and engineers can rapidly assess the flight control systems during more complex flight manoeuvres, capturing crucial data about how the jet will handle and perform, years before its first flight.

Collectively, this important work aims to dramatically reduce the time and costs involved in producing military jets, while maintaining the sovereign design, engineering and manufacturing capabilities needed to keep the UK at the forefront of global aerospace innovation.

Unless the upcoming EJ200 powered demonstrator is only a subscale model, the GCAP/Tempest will only be a fighter in the same sense as the Mirage IV or North American Vigilante. This demonstrator will have a lot less public impact than the EAP did in the 1980s. Especially when a developing country like Turkey can be so much farther advanced in a comparable program like the Kaan.

Yes its 2/3 the weight of it which is known for a while now. That said if it has 2 engines then it will likely be eurofighter'ish sized. Maybe that can be of use for something else later...

Edith: also can we get back to GCAP please because if my memory is right Most of that talk aint about it
Is the image in the tweet the confirmed design of the TD, or just another render? It's different to those that have recently come out, that's all. It's also ugly as sin.

Its the confirmed final design of the British demonstrator, was released yesterday along with them saying they were still on track for the first test flights before the end of December 2027.
 
Haven't finished writing up the briefing we (Craig Hoyle, Gareth Jennings, Tony Osborne, Tim Robinson) received on Monday afternoon. This press release and image were embargoed until 2230 today...

Few journalists on Twitter seem to have broken the embargo posting the images during the afternoon as well as a couple of news outlets, e.g. This Is Money had their story and image up in its first iteration at least as early as 9pm with several story updates afterwards and Aviation Week published the story and image behind their paywall hours earlier, in the small hours of the morning along with a second story featuring an interview with Lt. Gen. Antonio Conserva about GCAP mid afternoon.

Since there hasn't been any recent news about GCAP, let me ask a question from a layman's perspective:
In the end, do next-generation fighters need tail fins? Or is a tailless design the optimal solution?

You seem to have missed the latest render....its significant...

Mot likely just a cheap render, given how little it matches what we've already seen.

It's the first CGI of the demonstrator...confirmed as such.
 
How much is likely to change from this demonstrator to the final production models? Others have said it'll grow in size significantly.

See Tim Robinsons tweet...it's 2/3rds size, different wing and tail design and lots of other things...

For clarity, the embargo was lifted at 2230 on Wednesday. I saw no-one busting that embargo, though it sounds as though 'This is Money' may have done!

Different to what? AFAIK, the renders being thrown around of the finished product are still not confirmed as the official design.

Unless I've missed something he did not say that. He said 2/3rds of the demonstrator aircraft by weight is currently under construction, not that it will be 2/3rds the weight of GCAP/Tempest.

He (and other journalists) specifically said that BAE didn't reveal the actual size of the demonstrator, just that it will be "big".

The Flying Demonstrator is a pioneering programme which will prove crucial aerospace technologies, leveraging industrial experience, intelligence, and next generation combat air capability

A pioneering programme
Image+-+demonstrator+manufacturing+July+2024+2+other.jpg
The Demonstrator will be a piloted, supersonic aircraft that will help us to understand more about the advanced technology that is required to deliver a sixth-generation fighter jet.

Designing and developing a new combat aircraft like Tempest is a complex, multi-year engineering endeavour that involves advanced design, integration of cutting-edge technologies, rigorous testing, and collaboration to meet regulatory and airworthiness standards.

The UK has a proud heritage in this field, but it has been 40 years since the UK has led the early stages of designing and building a completely new and ground-breaking combat aircraft.

The progress we have made together with MOD and industry in such a short space of time has been remarkable, and the aircraft is set to fly within the next three years.

The latest programme updates

Manufacturing

Manufacturing and assembly of the main aircraft structure is underway on the country’s first crewed combat air demonstrator for a generation. More than half of the aircraft’s weight, including the fuselage and wings, is in build.

Crew Ejection
Working alongside UK crew escape specialist, Martin Baker, a team of BAE Systems engineers has led ejection seat trials, using a rocket-propelled sled travelling at speeds of more than 500mph. Experienced engineers have worked alongside junior team members to pass on vital skills which can be taken forward into future developments of Tempest.

Engine testing
Engineers at Rolls-Royce site in Filton, Bristol, have carried out aerodynamic engine testing, harnessing new advanced manufacturing processes to produce an engine duct which is uniquely shaped to slow the air from supersonic to sub-sonic speeds at the engine face. The intake has fewer moving parts than a traditional fighter jet design, enhancing the aircraft's stealthy design.

Simulated Flight Trials
In a first for military aircraft design, BAE Systems’ engineers have used auto coding to create safety-critical systems software in a matter of days rather than weeks. This enables rapid assessment of the flight control systems during more complex flight manoeuvres with the simulator capturing crucial data about how the jet will handle and perform, years before its first flight.

The demonstrator is an exciting once-in-a-generation opportunity providing experienced and young engineers alike a chance to contribute to an endeavour which really matters to our national defence and security.

Charles Woodburn, BAE Systems Chief Executive
 
Here was the state of the demonstrator almost exactly 1 year ago, with the demonstrator having "more than 50% of aircraft by weight now in the build process." Can the size be estimated based off of these two photos?
View: https://x.com/GarethJennings3/status/1816096411399934308
Those plug sockets in second pic lower right look like standard items. Use them to work out the main jig member widths and then work out aircraft frame dimensions using the first photo, which is usefully at 90 degrees.

Won't give whole aircraft length or span but it's a starting point.

I seem to recall Bill Gunston talking about Flight doing this for Buccaneers based on roundel sizes. Blackburn gave each DB aircraft different-sized roundels to try to stop it.
 

Like this part:

In terms of low observability, program engineers are leaning on “Taranis learning,” Godbold says, with the company currently testing a “lot of shapes” and “mold line styles” that will help inform design features for GCAP. Although a UK-only demonstrator, agreements in the Edgewing joint venture allow for the transfer of data and information from what is learned from the GCAP program, Godbold explained. “We leverage the very best out of each nation to generate the results.”

The Guardian's article also touches on Typhoon orders, and whinges at who we actually sell to, but does have an side-on view of the physical model.

ETA: I'm now wondering if the model is necessarily the same configuration as the other pics as Av Leak's article specifies they were shown "artist's impressions" ahead of RIAT at RAF Fairford, while Jasper Jolly's Guardian article features a visit to Warton.

This will be an exciting one to follow.

Interesting to see how this will compare with Mitsubishi's X-2 Shinshin. I know, I know, there's supposed to be a "generational" difference between the two but it's the closest comparison I can draw. Combat Air Flying Demonstrator's specifications are yet to be announced (?) but just going by engines it will be larger and more powerful than the X-2, maybe by a factor of ~1.8 (IHI XF5-1 to Eurojet EJ200). Resorting to Wikipedia Shinshin is/was close to projected GCAP territory in max performance (in the most simplistic "go fast" terms possible), M2.25 in burner, 1.28 in supercruise but I've no idea whether those figures are realistic or if it is still flying?

Slightly surprised by a BAE -only demonstrator at this point. GCAP (or Edgewing) itself is in good nick, isn't it? Not trying to throw aspersions, just wondering what uses parallel or beyond GCAP the Combat Air Flying Demonstrator could serve, if any? Now awaiting Leonardo to come up with their own too (AI suggested Fulmine, Aquila, Centauro, Veltro, Tempesta, Spirito, Ardente or Fenice might go with Italian naming traditions).

Reuben,
The demonstrator will support the definitive Tempest/GCAP primarily in exercising the people and the tools. It isn't a prototype and the production Tempest will look VERY different.

This addresses the problem facing BAE's people - that the company hasn't designed and built a combat aircraft from the ground up since EAP. This programme will 'rehearse' the actors, props and script for GCAP.

Yes, demonstrate the ability to go from concept to flying hardware once more.

Jaspar et al went to Warton for an 'overview' visit that included lots of stuff that the specialist media were already familiar with. That's why Craig, Gareth, Tony, Tim and I were given an in depth briefing.
 
Unless I've missed something he did not say that. He said 2/3rds of the demonstrator aircraft by weight is currently under construction, not that it will be 2/3rds the weight of GCAP/Tempest.

EXACTLY right.
