When you are late you got to something other than ordinary to catch up. I see nothing wrong in it. After all entire jet age, meaning jet engines coupled with swept wing design is originally a German innovation looted and exploited by those who are leaders in aviation today.
Yep fully agree c 130 , and iptn 225 of indonesia, chinese copy y 8 all looks same no need to invent wheels at least we should try making this plnes with imported engine other things will be our at least !!!
To start, just go with what is already available. Just stretch present SARAS into an ERJ-135/140/145 class airliners but with Turboprop (because it offers cost benefits over turbofan). As an airliner usually takes 3-4 years for certification.Start the development of entire family at once but with a spacing of 2 years between each for the maiden flights.
Then you should also know about this one saying "Just one crash and project will be scrapped".
We are Using ERJ 145 ? for our AEWC platform, can a stretched SARAS be used as a replacement platform. Then a scale up looks pretty obvious and also civilian role makes it lucrative for HAL..To start, just go with what is already available.

Subsequently, offer Turbofan versions also, for executive transport with an option for all-economy class configuration. Basically, offer a replacement of IAF's Embraer Fleet and an option to Airlines looking for speed on commuter/feeder routes.
Go all hog and see what happens. After all aircraft business is all about go big or go home.
Basic layout of SARAS and ERJs are similar.
Do not discount the turbofan vs turbojet aspect. Turbofan on the ERJ allows the 145 to fly faster, higher and be more economical on fuel than the Saras. Turboprops are not ideal for AEW.
Turboprop scores higher on fuel economy and endurance. Jets compromise these for greater speed. Even high bypass turbofans can't beat props with variable pitch. Becuase of these reasons, probably the most popular airliner in the low-cost Regional category is still ATR series............Of course with improving economy and better financial conditions low-cost airlines are also introducing CRJs, E-series etc on regional routes. But its another matter. It's trade-off.
If you are looking for Greater On Station Endurance, a Turboprop is more suitable. If you are looking for Faster On Station Arrival turbofan is more suitable. So its a game of trade-off and balancing.
I had spoken about replacing Embraer Legacy fleet of IAF which it uses for VIP transport.
Turbofans are better for covering distance quickly but the main purpose of AWACs is loiter which is best served by turboprops.
AWACS needs to fly at a higher ceiling for greater coverage where a Turbofan beats a Turboprop. Is there any turboprop which can maintain its loiter time while flying at 35000-40000 ft? I think not.
The AWACs will fly at its optimal cruise altitude for the best loiter time. The radar attached to it is designed for best operational performance at that altitude. The bigger the radar dome the higher you can fly with look down performance, for smaller radars flying high would make sea level discrimination more difficult. The reason an E-2C doesn't have turbofans isn't because they couldn't do it, it is because turboprops are more efficient for loitering over the fleet and they can pick up cruise missiles better at a lower cruise altitude.
ERJ145 with the DRDO NETRA has service ceiling of 37000 feet. The cruise altitude is 30000feet. So, SARS should be able to do the job if the size is increased. As of now, the payload is limited.
E-2C/D is an AWACS solution optimised for operations from a carrier deck with the primary role of protecting the carrier from cruise missiles by providing early warning. Also over the sea, the terrain is not uneven so E-2C/Ds can afford to fly low and yet detect targets of every size from considerable distances. Come over land where most of the air wars will be fought E-2C/Ds is nowhere to be seen.
For those who are satisfied with 30000 ft cruise performance and 8-9 hrs endurance at 300-400 km radius, it should be fine. We can offer it as an option to anyone looking for Erieye size AWACS. But for IAF it may not be suitable.
We only need transport planes for military cargo. Don't forget that oil is running out and hence these passenger planes may not be useful by 2030. We just need military transport planesI have heard good things from my professor regarding our Aerospcae industry.
If the government gets hell bent on developing our aerospace industry backbone then we can start making our completely indigenous Airplanes by 2030.
Eventually
Well get from this
To this
To this
To this
To eventually this
Bonus this
Remember we do not lack scientist or brains we just lack the much needed political and financial report.
WTF man oil isn't running out any time soon where do u even get this.
Oil is running out pretty soon. We use 4.2-4.3 billion tons or 30 billion barrels of oil a year. This is more oil than the entire volume of Chilika lake in India. Why do you think we won't run out of oil soon?
Only Arab oil is running out which is a good thing.
Actually, Arabs have 3:2 ratio of productions to reserve compared to others. Arabs will run out of oil much later. Even Russia and Norway has similar production to reserve ratio as Arabs.
Wrong, something is not better than nothing, because it needs to fulfil the minimum requirements to be useful in the first place. We can't accept developmenta that are below standards, just because they are indigenous, since it's the security of the nation that is on the line.
There are actually twice as many operators of the E-2 than there are of the E-3 and aside from the USN and FN, they are all land based. Then the next most proliferated AWACs is the Eryie which is also half turboprop. Then the Chinese only indigenous produced AWACS is also a turboprop. They are cheaper to build and cheaper to operate while giving a similar performance, it is the most efficient choice.
