Can we please kill the useless Ka-226T deal also like this? To the babus of this country, employ your enhanced skills of red-tapism primed over the last 70 years and nix this one please. You will have recovered the cost of chai-biscuit consumed by entire bureaucracy since independence. We already have the LUH, so no thank you. The Indian boy looks better too!

Why we use derated shakti engine ,not full capability ones

Because I don't want insas and I want t some uniformity.
We use type 56 too, can you believe it fckin type 56 !
Then why not SIG716? Its better, lethal and even cheaper. Or even Multi Caliber Individual Weapon System will be okay.
Why go for a bad expensive deal that will not have any tangible advantages.
All armies inducing IA recycle and reuse captured weapons. Their is no point of scrapping/disposing $10,000 work of hardware. Paramilitary units can always use them.
What happened to the Multi Caliber Individual Weapon System project?

First guy in the tweet is in a real hurry to meet his hooris- carrying a huge hard on to hell for the orgy!

derated shakti engine
'cause it is a 3-tonne heli capable of flying at 220 Kmph; service ceiling of 6.5 Km and a range of 350 Km with 500 kg payload.

Highly recommended reading: https://www.timtuckershelicopterworld.com/post/unlocking-the-mysteries-of-robinson-s-derated-engines

Short story:
The primary reason for the derating is to increase the altitude capability of the helicopter. A secondary reason or benefit of derating the engine is higher reliability and longer engine life.

Long story:
If Robinson only wants the pilot to use 131 hp why not put in an engine that that can only produce 131 hp? It would be lighter and probably a lot less expensive. The primary reason for the derating is to increase the altitude capability of the helicopter. As the density altitude increases the engine’s ability to produce horsepower decreases. So, if we started at sea level with an engine that can only produce 131 hp, how much horsepower would be available as we climbed up to perhaps three, four, or five thousand feet? Obviously, much less than 131. If we start at sea level with an engine that, in the case of the Beta, is capable of producing 160 hp but only let the pilot use 131 hp, then the engine will be able to maintain that 131 hp all the way up to what is called the critical altitude. The altitude at which the engine is only capable of producing 131 hp. For the Beta on a standard day this is a little above 5000 ft. Every engine change in both the R22 and R44 was made primarily to increase the helicopter’s performance at higher altitudes. Many of the early low RPM rotor stall fatal accidents were caused by overpitching the collective (increasing the collective when operating at full throttle). Increasing the altitude capability increases the altitude at which the pilot will be operating at full throttle, thereby reducing the pilot’s exposure to a possible overpitching situation. For example, at +20ºC a pilot in the Standard R22 (O-320-A2B engine) will be at full throttle at approximately 3700 ft pressure altitude. While a pilot in an R22 Beta II (O-360-J2A engine) will not experience full throttle until 6500 ft.



A secondary reason or benefit of derating the engine is higher reliability and longer engine life. It stands to reason that if the engine doesn’t work as hard it will last longer and be more reliable. If a pilot were to fly the Beta at maximum continuous power (124 hp) all the time, the engine would only be working at 77% of its normal horsepower rating, a cruise power setting for an airplane. As a result of this engine derating, Lycoming established to a 2000 hour TBO (time before overhaul) on the engine from the very first R22. To my knowledge, this was the first time a piston engine in a helicopter was given the same TBO as in its airplane counterpart. The R44 is the second.
Hope you understood that the engine was intentionally derated to conform to ASQRs/GSQRs pertaining to high altitude operations.

For some perspective, the workhorse Cheetah helicopter it will replace (and improves over) has a single Turbomeca Artouste IIIB turboshaft, 649 kW derated to 410 kW. LUH has 1 × HAL/Turbomeca Shakti-1U turboshaft engine, 798 kW derated- almost double the derated power over Cheetah.
