# 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 likely that the 35,000lbf thrust for F119(F-22's engine) doesn't include flat nozzles. For an engine thrust decrease of 14%, which accompanies flat nozzles, F-22's TWR would drop down to 1.18. It's known that Flat nozzles reduces the thrust of an engine from 14%-17%. 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.

* 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.

[AZADPAKISTAN2009]

Why is the thrust to weight ratio important for planes capabilities ?


Is that alone a meassure of performance

 

[no_name]

If your thrust to weight ratio is below 1 you can't increase speed when pointing directly vertical.

Because alot of people thinks that when fighter jets turn upwards they just change the angle while having the same velocity that the plane nose is pointed at, but infact when you turn upwards your vertical speed starts at zero, so larger T\W ratio means you can change velocity faster, while better aerodynamic design (and TVC) means the plane can change it's pointing direction faster (but both are important).

 

[AZADPAKISTAN2009]

Hmm I guess it makes more sense how it can be valuable asset to a plane to climb up faster then his/her adversary in air.

But don't the modern day missiles neutralize this advantage in a dog fight situation ?

 

[Manticore]

Thrust to weight usually determines acceleration and climb performance. Top sprint speed is largely dictated by thrust to drag and intake design.

"The speed of air entering the compressor of a normal jet engine must be subsonic, even for supersonic aircraft. While this doesn't affect subsonic aircraft, supersonic aircraft face a problem. This is because present design jet engines would be unable to handle the shock waves associated with supersonic airflow, and might be damaged.

Thus, for an aircraft travelling above Mach 1 speed, the airflow must be slowed down to subsonic speeds. In modern jet aircraft, this is done in a variety of ways through design of the Inlet. The complexity of these inlets increases with an increase in top speed. Planes with top speeds over Mach 2 require much more elaborate inlet designs. Thus, most modern aircrafts today rarely exceed the Mach 2 speed, usually limiting their top speed to Mach 1.8-2.0."

Some air inlets feature a biconic centrebody to form two conic shock waves, both focused on the lip of the intake. This improves pressure recovery. Some aircraft (Joint Strike Fighter, Mirage III) use a semi-conic centrebody.

Concorde, F-15, Foxbat, A-5 Vigilante use so-called 2D inlets, where the nacelle is rectangular and a flat inlet ramp replaces the dual cones just described. These allow good pressure recovery without spillover through the full range of speeds by matching their angle to the mach angle, but have problems with seals at high speed that is high pressure and temperature (like in a diesel engine). Inlet ramps allow for swept inlet cowls (F-22 Raptor, Joint Strike Fighter) to avoid shocks. They are sealed by viton or a metal sheet bend in direction of the higher pressure. At least one supersonic and one subsonic ramp is used, but for improved seal multiple supersonic ramps can be used. The boundary layer (something which the subsonic pitote inlet avoids by external compression) tends to separate and the smaller boundary layer of the ramp inlet is an advantage compared to the inlet cone. To avoid separation vortex generators are used, which mix the boundary layer with the free flow (or the boundary layer is sucked away through a porous surface, leading to drag). After the fan the hot slow intermixed air is passed by the engine, while the fast cold air is delivered to the engine.

After the engine the comparatively cold bypass air is used as an isolation between the engine exhaust and the walls. Again two ramps can be used to form a variable supersonic nozzle. Often a mirror-symmetric set-up is used with ramps on top and on the bottom.

There is one possibility for a stable, shockless supersonic to subsonic transition. This is used in transonic wings and would ultimately mean to send the air into a looping, forming a vortex: Then the final shock to subsonic speed is oblique with the subsonic region moving from the outside of the vortex to the inside.

Many supersonic aircraft (Eurofighter Typhoon,F-16) dispense with the conical centrebody and employ a simple pitot intake. A detached, strong normal shock appears directly in front of inlet at supersonic flight speeds, which leads to a poor pressure recovery.

Also NASA adds a gap through the whole compressor. Supersonic flow jumps over it by means of ramps, while subsonic flow is able to turn and exit through the gap. In this way a stall is easier to remove [1]. Also there are plans to measure the air in front of the inlet to detect turbulences and adjust the inlet in real-time.--wiki

I guess this explains why Jf-17 is rated at 1.8.

Does anyone know the maximum tested speed?

1.8 is huge...........
I think its near to 0.8 thurst to weight ratio

 

[Chanakyaa]

AS the List suggests LCA has better performance here.

JF is 0.83 n LCA 0.87 ......not a hude difference...
1 or above 1 is the demand of modren AC's

 

[MAFIAN GOD]

IT IS THE BEST THREAD ON PDF GOING ON.
IT GIVES INFO. OF ALMOST EVERY MODERN PLANE.

I HAVE A QUESTION.PLEASE HELP.
WE HAVE A PROBLEM IN DEVELOPING ENGINE OF LCA.
HERE T/W RATIO OF LCA IS 0.87(I SUPPOSE THIS IS THE RATIO BY KAVERI ENGINE)
ALSO MIRAGE-2000H HAS T/W RATIO 0.88. IAF INITIALLY INTRESTED IN THIS PLANE FOR MMRCA COMPETITION.
DON'T YOU GUYS THINK IAF IS BIASED ABOUT OUR INDEGENOUS TECHNOLOGY AS THEY WANT LCA'S T/W RATIO >1 WHILE THEY WERE INTRESTED IN MIRAGE-2000H?

ALSO JF-17 HAS A LESS T/W RATIO THAN LCA.SO WHAT IS THE POINT IN IMPORTING ENGINES WHICH IS LEADING IN LATE INDUCTION OF LCA ? NOTE THAT LCA IS NOT GOING TO BE A FRONT-LINE FIGHTER IN IAF.
REGARDS......

and the munition lodaing would play a role in determining the actual ttw ratio in combat...
nice to know that the new GE engines have taken care of the LCA being overweight problem...

Hi, I wanted to start of by saying this is a very informative and good thread.

Currently the LCA is powered by the F404 engine (19,000 lbf/85 kN), but it will be powered in the future by the stronger thrust F414 engine (22,000 lbf/98 kN). This will require a slight redesign of the fuselage, but it is a much more powerful engine. This should crank up the T/W ratio for the LCA.

I was under the impression the JF-17 had a T/W ratio close to 1, with the RD-93 engine. However, this might be in a completely clean configuration though, with no ordanance and/or fuel tanks. Please look at the statistics at the bottom of the attached link. Maybe the WS-13 (when completed?), combined with using composites, will increase the JF-17's T/W ratio. Thanks!

I can see why people say the Su30 HAVE BRUTE POWER AND speed as well as TVC agility on the SU35 & SU30MKI would make it a beast of a plane.

Also very surprised that PAF are not bothered about the under power of the Thunder compared to both F16 & J10 and more importantly the current LCA (WHICH THE INDIANS ARE REAL BOTHERED ABOUT) and the mk2 tejas which will be close to 0.95 thust ie 10% better than mk1..

 

[kirankumar299]

Can we compare WS-13 to Kaveri engine (GTRE GTX-35VS)??

 

[Safriz]

JF-17's Thrust to weight ratio is disappointing,and that alone drops it from my "Cool list"...
