General Electric F414 was evolved from F404.
Few major differences are
1. Large fan section (13 cm longer) resulting increase in airflow mass by 16%,
2. First three stages of HP compressor are blisks (integrally bladed rotors) rather than dovetailed blades (individual removable blades). Probably HP compressor stages are reduced to six for more advance derivative.
3. Combuster shortened by 2.5 cm
4. Afterburner section shortened by 10 cm
5. FADEC guided F414 uses fuel from aircraft’s fuel system as hydraulic fluid to actuate “fueldraulic” system (actuators) of convergent-divergent nozzle in the afterburner section.
16% increase in airflow mass and improved FADEC resulted in larger thrust than F404.
57.8 kN (13,000 lbf) military thrust
97.9 kN (22,000 lbf) with afterburner
Now referring to the article uploaded by you on WS-13 and RD-33/93 up-gradation, the increase in mass airflow is 6 % for RD-33 after inlet fan modification. This increase will certainly improve engine thrust. Klimov is claiming that max thrust of RD-93MA will be 93kN. However mil thrust is not specified.
While searching on RD-93 data I found an old but very informative article at
http://www.leteckemotory.cz/motory/rd-33/
The article mentions about a derivative RD-33K which is to be used in naval version of Mig-29. The modifications mentioned are similar as discussed earlier. Interestingly full specifications of RD-33K are given in the article and some parameters are mentioned below:
55 kN military thrust
88 kN with afterburner
94 kN extraordinary thrust
Another interesting fact is that Indians were offered to manufacture RD-33 MK at their facility (year 2004) and this derivative was developed from the RD-33 3M Series and retains all of its benefits such as extraordinary thrust, corrosion protection, smokeless engine, reduced thermal visibility, tropical operation, BARK-88 control block ie upgraded FADEC, etc. and thrust vectoring nozzle. Some specs are as under:
53 kN military thrust
88 kN with afterburner
93 kN extraordinary thrust
PS: Most probably more fuel is being injected in combustion chamber to achieve extra ordinary thrust during takeoff from aircraft carrier. This selection must be restricted for very short period and only to be used during takeoff or critical combat situation, as prolong use may cause excessive turbine fatigue or failure due to high inlet turbine temperature (T4).
The article also mentions that four RD-33N were exported to china in late 90s, where they underwent tests on
FC-1. RD-33N were designed for Mig-21 and its export variant SMR-95 was offered to South Africa to power their Mirage III and Mirage F-1. Hence RD-93 was developed from RD-33N and exported to China to power FC-1/JF-17 and J-10. By the end of 2004 China negotiated to produce RD-93 engines under license. The specs for this engine are given below:
50.4 kN military thrust
83 kN with afterburner
A cheap solution to enhance air war capacity!!!!
This article also revealed in great detail that how SMR-95 was evolved. It is developed to power South African Mirage III and V but the export contract could not be materialized.
There was a rumor that PAF was negotiating to buy RD-93 engines directly from Russia. Why?
Note that China already bought 100 RD 93 engines and further procurement of 500 engines were under negotiation (probably materialized as around 130 JF-17 were already built)
PAC MRF overhaul Mirage III and V aircraft. During overhaul the aircraft is completely striped off and detail inspection of airframe structure is being carried out. Defective structures can be replaced with new ones prepared at manufacturing facility. Appreciate that AMF is capable to manufacture most of airframe structure of JF-17 and K-8. That means they have the capability to build bulk heads to replace defective ones for Mirages. By doing so, airframe life can be extend may be for another 20 years or less.
If refurbished airframe with extended life powerd by new powerful RD-93/SMR-95/RD-33N engine fitted with latest avionics suits (ECM/EW), AESA radar, HMD, IRST, HUD, glass cockpit and integrated with every available AA, AG and AS weapons, the Mirage will become a super Mirage – a lethal 4++ weapon platform.
