Tu-128 # Data from Official Company & Military sites, Aerospaceweb.org, Airwar.ru, Globalsecurity.org, Fas.org, Warfare.ru, Wikipedia.org & its References, and Other Sources. # Weight in lb, and Thrust in lbf. # 3505 kg = 7727 lb # Not all of them are Fighter Planes. # Some of the Fighters' data couldn't be obtained, and hence could not be included in the above list. # Individual engines' SFC(Specific Fuel Consumption) & Individual aircrafts' standard Air-Air payload weight, based TWR cannot be determined due to unavaliability of SFC data for Older Engines. Even in the case of some Newer Engines, SFC data is not avaliable. # It's unclear whether the 35,000lbf thrust for F119(F-22's engine) is the actual thrust output. It's known that a Flat nozzle reduces the thrust of an engine anywhere between 14% to 17%. Further it's mentioned in official sources that the engine is of 35,000lbf Class, meaning the 35,000lbf number is not the precise engine output, and the actual output is somewhere around it. Generally, in official publications, when an engine output is mentioned in the form of 'Class', the actual output is less than the number given. It could be that the engine can very well produce 35,000lbf with normal nozzles during testing, but the mating of Flat Nozzle(instead of the normal Round one) reduces the thrust, hence the 'Class' designation for the engine's output. For an engine thrust decrease of 14%, F-22's TWR would drop down to 1.18. Given the fact that the F-35's engine, which is a derivative of the F-22's engine, but newer & bigger than the F119 engine, has a thrust of 39,900lbf with round nozzles, it's likely the 35,000lbf fig for F119 is also for round nozzles. F-35's engine F-135, just recently got its thrust upgraded to 43,000lbf. To further illustrate the data sheet's/brochure's failure of mentioning the loss of thrust for Flat Nozzles, the F-117's F404-GE-F1D2 engine which is a non-afterburning, flat nozzle engine[1], is mentioned as having the same 10,600lbf[2] non-afterburning thrust as the F404-GE-400 engine[3]. F404-GE-F1D2 is basically a non-afterburning F404-GE-400 engine with a flat nozzle.[4] * Klimov States that Thrust as "Take-off emergency mode" ** The conditions for 21,829lbf Emergency Thrust are limited to 3 Minutes and Altitude less than 4000m. *** Empty weight + 7727 lb exceeds max takeoff weight. Except Mig-19 all other less MTOW(Maximum Take-Off Weight) fighter planes are omitted. **** Official tejas.gov.in Website claims the Thrust of F404-GE-IN20 as 20,200lbf which contradicts with the manufacturers' claim of 19,100lbf. Most likely the 20,200lbf figure is for Emergency Thrust. Also Tejas has gotten heavier by about 60kgs thus bringing its TWR to 0.86 from 0.87 . @ Normally, Emergency Thrust is carried out at Take-off near the sea level where the air is denser. It is normally employed for scramble missions, OR/and to reduce the Take-off distance if the Aircraft is heavily loaded with fuel and munitions, OR/and if the runway is shorter. It may or may not be employed during dog-fighting, but it heavily depends upon the altitude and is time constrained(for example see **). ______________________________ Comparison of TWRs using variable weights(Full Fuel) Updated 11 Feb 2010: http://en.wikipedia.org/wiki/Thrust-to-weight_ratio#Fighter_Aircraft Old Data: https://www.angelfire.com/falcon/fighterplanes/images/articles/thrustweightratio.jpg Related Articles: Which is the No:1 best BVR fighter in the Indian Subcontinent ?
