Hello Swapnil,
It's very nice to know your ambition of joining IIT Kanpur for your graduation in aerospace engineering after completion of your diploma. IITs indeed take students for their graduation programs but here diploma is treated as equivalent to 12th and whatever rules are applicable for JEE mains and JEE advanced for 12th or applicable for diploma also. The simplest to understand is there is no lateral entry in IIIT but diploma be considered as equivalent to 12th if you have scored 75% and more in diploma you become eligible to appear for JEE entrance and subsequently to JEE advanced examination. The admission to this Institute will depend entirely on how you score in JEE advanced and what is your merit in your category.
Best wishes to you.
