SouthViper Posted November 27, 2022 Share Posted November 27, 2022 Hi, I would like to know if the prototype Tornadoes would be able to drive the turbine reversers even with the post combustion activated? Or would there be a device that prevents this action? Well, perhaps when the Tornado was standing parked for exibition only was it possible to show open wide exhausts together deployed reversers even just for the show? Thank You all Southviper from Brazil 1 Link to comment Share on other sites More sharing options...
exdraken Posted November 27, 2022 Share Posted November 27, 2022 Interesting question! I assume you want open nozzles and deployed trust reverser buckets deployed no? I do not know specifically for the Tornado and its RB.199 engines, but usually nozzles open at idle ( to reduce thrust even more ) and at afterburner ( due to nozzles efficiencies at supersonic gas / fluid speeds) I definitely do not think that you could activate the afterburner with thrust reversers deployed, due to excessive heat and excessive thrust etc... On the ground, in maintenance mode nearly everything is possible... And last question, the Tirnado nozzle is not very different regarding closed and open nozzles... do you observe differences in kits? Link to comment Share on other sites More sharing options...
Selwyn Posted November 27, 2022 Share Posted November 27, 2022 It would never happen. Afterburner is used to produce more thrust; i.e. make the aircraft go faster. Thrust reverser buckets are deployed to make the aircraft slow down (on landing). Two completely opposite conditions, There would be no occasion you would need to use both together.

Selwyn Thinking further on that use of reheat and reversers together would increase the linelihood of hot gas re-ingestion and consequent increase in TGT (Turbine Gas Temperature) resulting in reduced TBO (Time Between Overhauls) and overall engine life, not something that would appeal to SEngOs or Ministry bean-counters. Bearing in mind also the "carefree handling" design philosophies of Tornado is/was there a mechanical and/or electronic baulk preventing selection of reheat if the reversers are deployed or deployment of the reversers if reheat is lit?

tweeky Posted November 27, 2022 Share Posted November 27, 2022 (edited) Thrust reverse could be preselected prior to landing, to do this you had to rock the throttles outboard (this would also select lift dump both wing spoilers deployed) Lift dump and thrust reverse (TR) was triggered but the Weight on wheels (WOW switch) so I doubt the TR would deploy inflight with the WOW switched un-made. There was a lever in the cockpit for "taxi Nozzle" this opened the nozzle up. I think the Tr could be deployed with the nozzles in Taxi. As part on the service routine on Tornado the buckets had to be inspected every X amount of hours. The buckets deployed via a screw jacks these jacks were air driven, But there was a small panel on the air motor you could take off and drive the buckets out via a ratchet drive once you'd unlocked the buckets for inspection/replacement.

DougC Posted November 27, 2022 Share Posted November 27, 2022 Short answer is no. Also pretty sure you couldn't select TR with the Taxi Nozzle open. Link to comment Share on other sites More sharing options...
scotthldr Posted November 28, 2022 Share Posted November 28, 2022 Yes, you can select TR during taxi. Link to comment Share on other sites More sharing options...

SouthViper Posted December 5, 2022 Author Share Posted December 5, 2022 Hi everybody Thank you to each one, in fact I am planning to just show the widened exhausts and the Thrust reversers at mid-way, not completely deployed.
