Gadeshi, please show me the number or AVERAGE (not war time) 2 housrs maintenanace. Using the same message, you could answer about cell and engine lifetime please?
not so fast and not so simple man ...
if i am using more nos of engine in russian origin then i am also paying less in terms of initial acquisition costs - capex and also for each and every subsequent engine costs
now calculate the saving on capex & teh purchase of subsequent engine in terms of rusian origin and prices
then use the opportunity costs of money on those savings
then compare total costs at the end of life for both russian & dasault (rafale )
the russian works out cheaper option
you know the gujarati way of doing business calculations & calculation of rotating the money ?
i know and so does modi :bounce:
also we agree to technical higher life of western engines but it does not mean the engine wont suffer bird hits and not be needed to be changed
In iAF
57% of accidents / incidents are non Technical
major problem for IAF is Bird hits and the obvious damage is to the engine
now suppose
i have a russian engine which costs say x million and with life of y years and a western engine which costs 2x million and with life of 3y years
but
43% of incidents of bird hits will cause some extent of damage to both
now consider case 1
where entire engine need not be replaced but some parts needs to be replaced
then russian engine parts will be cheap
while wesern engine parts will cost2 times the russian one or maybe more
an case 2
where entire engine needs to be overhauled / replaced
here again russian ones obviously works out to be cheaper
as if engine needs to be replaced then my investment or capexon western engine will go in vain as i will need to replace it inspite of its long cell life etc etc etc too will go in vain
so you see
lab life or brouchure life of enigines dosent work out to be better however you try to spin it
sure western engines may be more easier to repair / overhaul / maintian but will cost as hell
and those costs should not always be calculated on lab conditions but actual field conditions
