INDIAN TEJAS mk1 V/S PAKISTANI JF17 THUNDER block 1
where as on the other hand the chinese JF 17 uses a klomov RD 33 engine which offers a thrust of 44.9 KN and a with afterburner it offers a thrust of 84.8 KN
E) Tejas has a smooth upper wing body blending i.e. having no clear dividing line between the wings and the main body of the plane This helps to avoid early detection as the corner reflections from AWACS aircrafts searching from above resulting in lower RCS.
The HAL Tejas is an Indian single-engine delta wing multirole light fighter designed by the Aeronotical development agency (ADA) in collaboration with Aircraft Research and Design Centre (ARDC) of Hindustan aeronotics limited (HAL) for the indian air force
The PAC JF-17 Thunder or CAC FC-1 is a lightweight, single-engine,4th generation multi role fighter developed jointly by the pakistan aeronotical complex (PAC) and the Chendgu aircraft corportion (CAC) of China
SPECIFICATIONS
1 speed
2 RANGE
These are the comparisons of ferry ranges with droptanks
Jf17 can carry 3 droptanks of equal volume due to which its range is higher than that of the TEJAS
Although the JF 17 have higher ranges as compared to TEJAS MK1 but the main problem with JF 17 block 1 is that it is not able to do air to air refuling due to which its range gets limited and on the other hand the TEJAS MK 1 have non retractable refuling probe due to which the range of tejas can be increased to almost double of the original range
3 payload carrying capacity

Delta wing shape of tejas offers it a higher number of hard points

Here we can clearly see that Tejas has more options for weapons as compared to its counterpart JF17 THUNDER
Both of these aircrafts are made to perforce both air superiority role and ground attack roles
In the case of JF 17 Thunder pakistan have the backing of china and all the parts of JF 17 are manufactured in China and are exported to pakistan where it is assembled at PAKISTAN AERONOTICAL COMPLEX KAMRA due to which the productivity of the chinese aircraft is high as China have a huge manufacturing industry as compared to both pakistan and India combined
Because of which pakistani air force was able of induct around 132 aircraft in their inventory
The main problem with TEJAS is that it's manufacturing speed is too low and due to which only 23 TEJAS have been delivered to the indian air force of the total order of 40 TEJAS mk 1 and a additional of 83 TEJAS MK1 A are also on the order with the HINDUSTAN AERONOTICS LIMITED
ENGINES
Tejas uses a GE F404 engine which offers it a maximum thrust of 53.9 kilo Newton (dry) and a thrust of 90 kn of thrust with afterburner
We should remember that although their might not be any great difference between the thrust of engine's of both the aircraft but the maintainence of a average American engine is far more easier than the the average soviet engine since the RD 33 IS A SOVIET era engine its maintainence costs are very high And is also difficult to maintain
And also the life of a American or a western engine is around 8000 to 9000 hours where as the life of a average soviet engine Is around 2000 to 4000 hours which means after their life cycle they are crap and also the western engine's are much more fuel efficient then the soviet engine's which means the GE F 404 engine used in tejas is far more superiour then the SOVIET RD33 engine
HOW DOES TEJAS CAN HAVE A HIGHER RATE OF SERVIVABILITY and HAVE A LESS RISK TO BE SHOT DOWN BY THE PAKISTANI JF 17
1. STEALTH CAPABILITY
Stealth is a capability which is used to minimize the radar cross section of a aircraft lesser the radar cross section less the chance of a aircraft to be caught by a radar and a aircraft with this property can be more effective in the conditions of war as it can penetrate in the enemy's heavily defended territories
Though tejas is not a complete stealth aircraft but it has some physical features which enable it to posses some of the stealth capabilities
A) SMALL SIZE
tejas is much smaller than we think of a regular Aircraft it is actually the worlds smallest fighter aircraft
Smaller size of tejas provides it with a less surfaces which can be vulnerable to radar And hence it ‘looks’ small in radar automatically
B) MATERIAL USED IN Tejas’ airframe -
THE airframe of tejas is made up of advanced composite material 90% of surface area which is a bad reflector of radar wave so reduces the radar cross-section. The JF 17 LACKS such properties as it is almost completely a aluminum body due to which its radar cross section is very high
C) Tejas has wing-shielded Y-duct inlet. The engine fan blades are a prominent contributor in RCS, therefore Y intake buries the jet engine inside the fuselage so no engine parts are visible and thus increases the stealth characteristics.
Where as in the JF 17 although the chinese have tried but the engine is so much bigger in dimensions than the INDIAN engine they can barely hide it with a little y shape
D) Tejas has Indium Tin Oxide coating on canopy. Radar waves normally enters the cockpit, gets reflected from objects & possibly returns to the radar. Even the HMD (Helmet- Mounted Display) of pilot itself contributes to RCS. To prevent this the canopy of Tejas is coated with a thin film transparent conductor of Indium Tin Oxide. The coating is thin enough that it has no adverse effect on pilot vision and can reflect the radar waves away from the radar antenna.
2). The radar cross sections
Proof of 10 m² rcs of jf 17
Which means the JF 17 have a higher probability of being shot earlier as the radar which is installed on the tejas mk 1 can detect the JF 17 much before then the JF 17 can detect tejas which also means that Tejas can come even much close to the jf 17 and can lauch its AIR TO AIR missile without being getting detected by the JF 17
The radar which the TEJAS uses is the ELTA ELM 2032 RADAR which have the capabilities of to detect 150 km ranges for 5m² RCS since the radar cross section of JF 17 is 10 m²so there can be probability that Tejas may catch JF 17 much before jf 17. SO for the ELTA ELM 2032 , JF17 is just like a loud speaker in the air
where as the JF 17 uses the KLJ 7 pulse dappled radar In look down mode 100km for 5m2 In look up mode 150km for 5m2 RCS In look down mode 110km for 3m2 RCS 200km for KLJ-7A.
But the radar cross section of tejas is 0.5 m² so the JF 17 can not see the tejas at a distance higher than so if we apply simple mathematical unitary method then we would find that the KLJ 7 will pick up the tejas at minimum to minimum 10 km away from the JF 17 but If we give some liberty to the pakistanis then the JF 17 may pick up the tejas at 60 to 70 km due to the external payload but that can not be compared to the 150 km range of a proven Israeli radar
Electronic warfare capability
Both the Indian the chinese aircraft have almost same features in electronic warfare but Tejas uses mainly Indian and Israili electronic warfare equipment which are the most battle proven as the israili electronic warfare suits are the number 1 in the world this can be prooven by the example that most of the US airforce aircrafts uses israili electronic warfare suits and also one of the reasons that the israili EWS Are the best is that they consume minimum electric power
whereas the jf 17 relies on the Chinese electronic war fare equipment which is never battle prooven and are not effective
For example - every month we come to here about the American retaliative air incursions In the chinese air space in the south china sea and even once the american U2 SPY plane reached 14 km closer to the chinese main land so I'd the chinese can not stop a 66 years old aircraft with the best electronic warfare technology which the chinese have then how come the jf 17 can have better technology as compared to the battle proven israili electronic warfare suits
CONCLUSION
both the aircrafts are capable and can give challange to each other in their respective domains but when it comes to air to air dog fight then tejas will always have a upper hand on the JF 17 because of its low RCS and some of its stealth capabilities
