Thanks but the posters above you have already explained that in a much polite mannerYou can't shove a high thrust engine into a small fighter aircraft.
RD93 is a medium thrust engine and WS10 is a high thrust engine. The huge difference of thrust will lead to the disorder of aerodynamic layout, and finally reduce the combat effectiveness of the fighter.
Both had the right idea. Upgrading to turbofans does improve fuel efficiency (if done correctly). MiG-27 was not exactly a fighter but bomber and the British were supporting their local industryIndia once forcibly installed AL31F for MIG27, which finally led to the decline of fighter performance. Britain's replacement of the F4k engine also led to a decline in fighter performance.
Thanks for the detailed answer. The JF-17 powered by the RD93 was a compromise. PAF went for it because the French option was not available, the British too expensive and no mature Chinese engine available at the time. Were it not for the RD93 the JF-17 was pretty much doomed. Even in it's current state the RD93 powered JF-17 is not deemed fit by the PAF to replace the Mirages hence those jets soldier on. With a reliable engine from China now available and in use and with the possible acquisition of J-10, is it not time to re imagine the JF-17 around a WS-10 engine by making it a medium class fighter? PAF has been on the lookout for a better engine for the JF-17 from the beginning and at the start of every new batch we have to hear that same self soothing statement again and again that the PAF is 'happy' with the current powerplant.So if you want to replace the WS10 with JF17, the aerodynamic layout, inlet and rear fuselage of JF17 will have to be modified. This is tantamount to redesigning a fighter. Moreover, JF17 using WS10 will no longer be a light fighter, but a medium fighter at the same level as F16 and Rafale. This will lead to a significant increase in aircraft manufacturing costs.
Nice cheerleading... You seem like a proNicely explained to the newbie.
