Rohit,
Per those dimensions of the IL 76 even the T72 wouldn't fit in since its width is 3.59 m not 3.46m
However per the images in
this article and the article itself we know the IAF did get the T72 on the IL76 and transported them to Jaffna and Leh.
Furthermore per that image - I see more than 4 cm on either side of that T72 - which should accommodate the width of the T90.
Just so that we are clear about a distance of 4 cm - it is ~width of 4 adult fingers - There more than 4 fingers of space on
BOTH sides of the T72 in that image - plenty to accommodate the T90.
I do not see a need to spend an extra $ billion and a half on
sanction prone equipment when it can be done at half the price with equipment we already have, and more importantly which is not sanction prone
Anyway I would like to hold the C17 to the same standard of proof its supporters are asking of its competitors. I see no photograph of the Arjun on the C17 and see no evidence that the C17 is certified to carry the Arjun. Holding the C17 camp to the
same standard of proof, lets see some images of the Arjun on the C17.
Lets see the certification of the C17 to load and carry the Arjun, even an image will do. Elsewise what we have is a marketing push by certain person of unknown origin for a particularly expensive
sanction prone expensive to buy, expensive to maintain aircraft. I also see these people setting up strawman arguments in order to demolish them, while providing no evidence of their own in support of their claims.
For instance the C17 supporter here has been stating the C17 can land within 3500', while also stating that the C17 can carry the Arjun. It seems to me the George has been trying to imply the C17 can land within 3500' with an Arjun as payload. Not that it has been explicitly stated by him, but neither has he bothered to correct this impresison whenever it was stated by others from time to time.
I see no supporting evidence (by this I mean actual numbers) for the payload the C17 actually carries when landing within 1100m (3500') - I need evidence of payload, fuel, altitude, temperature, velocity etc. Talk of 1100m landing capability is cheap marketing glitz.
Lets take the claims of the purported advantages of the C17 vs its rivals one at a time and examine it in detail.
1. C17 short field capability - allegedly 3500'.
Examining this claim in detail we suddenly realise - we have no evidence other than manufacturer statements.
Lets assume the best case 55T Arjun payload, low fuel and landing velocity of 1.1x stall velocity which is lower than 1.3x stall velocity (the usual standard for landings) and at sea level. The lower landing velocity means the aircraft will land in a shorter distance, it also means the aircraft has a higher sink rate, which
translates to higher impact on the landing gear on touchdown. The landing gears are rated for a certain number of cycles (landing / take-off) before they have to be serviced, this is completely different from the aircraft airframe maintainence cycle. With a 20% greater impact (and we are not even considering the consequences of the difference when landing with no payload) those LG maintainence cycles are gone for a toss. It also means with greater stress those LG's are prone to greater failure rates than with normal landings. Remember the manufacturer is sating its LG maintainence cycle only for normal landings not the over stressed landing with a 55t Arjun and the short field. Higher wear and tear on the landing gear means more costs and more spare parts (again these
spare parts are also sanction prone)!
If we assume landing is to be at Leh, there is only loud silence from supporters and more importantly the manufacturer.
So we can lay this claim to rest right now. This is no advantage. Sea level landings within 3500' while carrying the Arjun are not required by the IAF. Doing so will increase costs on an already expensive
sanction prone aircraft.
--- In my next post - we will compare maintainence and its complications.
