Bristol 188 [edit] now including FT.155-like submissions as well

[PR19_Kit]

There seems to have been as many quoted thrust ratings for the Gyron Junior as the number of engines built....

In various places the Gyron Jr is quoted as having 7000 lbs, 8000 lbs, 10000 lbs dry but no-one seems to note the reheated thrust, maybe because the 188 was the only re-heated application for that engine. Note the 'Junior', the Gyron itself was a monster of a different feather entirely, having a dry thrust of 18000 lbs and that was in 1955!

Seems to me that us whiffers should invent the Gyron Senior, so awe-inspiring that strong men would wet their pants on start-up.

Oooh yes, I DO like that idea! Imagine a Sperrin, the test-bed for the original 'big' Gyron, with a 747 sized engine pod mounted mid-wing!

Does anybody do a 1/72 Sperrin (at a reasonable price)?

Does £86.40 (138 AUD) qualify as "a reasonable price"? 

Magna resin SA4 Sperrin MAG7291

Does that include the fork lift truck to carry that amount of resin around your model room?

Both BSP: Fighters and Hygate's 'British Experimental Jet Aircraft' quote 10000 lbs dry, 14,000 lbs with reheat for the Gyron Jr.

All the information on the Buccaneer S1, the largest user of the Gyron Jr, quotes 7100 lb.

It looks like there were different marks of the engine, but it's very poorly documented. I'm surprised that Blackburn swapped to the R-R Spey if the later Gyron Jrs produced 10000 lbs thrust as the Spey only put out 1000 lbs more. I see the dark hand of the R-R Marketing Dept here...

Perhaps they were looking more for better fuel economy than necessarily greater thrust?  Mayhap they also saw that the Gyron wasn't going anywhere whereas the Spey was and therefore had greater potential?

[The Wooksta!]

The Buccaneer's performance with the Gyrons was decidedly marginal, plus it was thirsty - not something you want for a carrierborne aircraft miles away at sea!

Have a word with General Melchet.  He built the Magna kit and was less than complimentary about it.
