    I wonder if the Sabre engine in Skylon is able to handle bird strikes ?

      Theoretically it needs to be tested at twice maximum speed for civilian applications. It could be difficult accelerating a chicken to Mach 11. Additionally not many birds fly at 150,000ft.

        I think Sully would appreciate if the turkeys were shot at it even M4...somewhere at Mont Blanc region.

          Italy is showing interest in participating in the Tempest programme.

            You would think that RR would want to partner with either P&W or GE on the ACE (Adaptive Cycle Engine)??? This would be a huge plus for the former. As it could get a share of the PCA and/or NGAD. In addition to the Tempest...........That would be a smart move in my opinion.

                If partnering with PW or GE, then the US would have a veto over sales, if it's purely UK tech, then we could sell to whomever.

                Of course if other areas within the airframe have US based Tech so would be a moot point.

                  Doubtful the UK would sell to anybody that the US wouldn't. Also, the UK has no problem partnering with the US on the F-35. So, honestly see no issue here.....

                    What would be the point though? RR doesn't need help designing engines.

                      It's not so much a question of the UK selling to anyone that the US wouldn't, as the UK selling to people that the US wants to sell to. There have been cases of the USA refusing permission for US parts in UK equipment to be sold to a country, while simultaneously trying to sell equivalent equipment to the same customer.

                        Maybe but it's all trade offs. As the US has a far larger share of the market. Which, would give the UK access too.....Yet, I get your point.

                          Really, I didn't know RR had a Adaptive Cycle Engine (ACE) / Variable Cycle Engine currently in development??? You have a source???

                            ACE is far from a new thing tbh. Reinventing wheel... see M53, J79, or even Kaveri etc.

                              What's revolutionary about diverting a bit more air around the core under certain flight conditions? It's just plumbing.

                                Can you elaborate?

                                  all of them have adaptative cycle using different systems. Kaveri being a special case, its third flux being used ot have a flat rate whatever speed or altitude.

                                    You mean it has a dump valve? And that sounds revolutionary to you?!

                                      Three flows engine seem revolutionary for you? See Tornado. Whatever dump valve, "souris" etc. An adaptative cycle is an adpatative cycle.No less no more.

                                        The SR-71 also had an adaptive cycle engine and that's early '60s/late '50s design and engineering. I don't think we're talking about a 21st century cutting-edge invention here. Many engine projects have just avoided adaptive cycles for reliability and cost reasons historically, most notably the selection of the F119 over the YF120.
