apparently our top notch or even upper mediocre students are not interested in core physics/ mechanical thermodynamics, as much as they are interested in doing some computer/software job or sitting in the high salaried chair of some multinational company after doing an mba. you can make blue prints of an aircraft/rocket chassis with software modelling, but can you do the same with an engine ?
they need to conduct multiple tests, analyze the results, do the modifications/upgradations, then testing again - as much as 4-5 cycles to make sure the people to be sitting on top of those tons of fuel will walk on earth after next few days. can it really be done in 2-3 years ?
2025 will perhaps be a better goal to think about.
