Shoreham as a Film Star

[Garry Russell]

Yes Tobt but there are other types as well not just the Fan i125.I know what the F stands for.

What aboput the JetStar 731 are they Garrett?

The turbojet powered JetStar remained in production until mid 1973, by which time development of the turbofan powered JetStar II had been announced. The JetStar II differs from the earlier aircraft primarily in its four Garrett (previously AiResearch and now AlliedSignal) TFE731 turbofans with their significantly improved fuel consumption, resulting in substantial improvements in operating costs, range and lower noise levels, while more power allows a higher maximum takeoff weight.

It would seem so. They were very widely used on bizjets in the 70s and 80s.

Re the 125, the "F" not only means that it has has tubofans, but that it has been re-engined with them, hence the -700, -800, -1000 and Horizon do not have the "F" designation. G-BFAN (c/n 25258) was originally laid down as a 125-400 but was pulled from the line and converted (lengthened and modified) as the prototype -600, G-AZHS. It was then re-engined and upgraded as the -700 prototype but has since reverted to the designation -F600B as really its a UK spec -600 that has been re-engined to appear as a 700, for example.

Hi Toby

That looks like it as it seem to be used to show it has the new compliant engine. Air Reaserch or Honeywell, I take it those are jus two alternate names for the basic same engine?

Yes, Garrett owned AiResearch and they were bought by Allied Signal who merged with Honeywell to form a company still called Honeywell who were nearly bought by GE!

Similarly, Avco acquired Lycoming and were then bought by Textron who sold all bar the piston engine bit to Allied Signal who were merged with (acquired by reall) Honeywell, hence the 146/RJ/RJX families engines having various different manufacturers' names!

Thanks for that Toby
