Train 18 appears to be our attempt to catch up with the present high speed passenger train transport with tech like aluminium body and bogies having own motors. While reading on shinkansen propulsion came across a term called VVVF (Variable voltage variable frequency) drive. The bogie motors are dri...

Regarding 747 on japan domestic routes, googal tells me they have been retired and replaced by b777 on account of feul effeciency. Since they have to compete with bullet train , 4 engines would be at a disadvantage.

For such slot constrained places and p2p to major metros perhaps we should look at 787 and a350 sized planes They will run full Japan uses all economy 747 on dotmestic main routes and was biggest client of 747 flights less than 2 hrs !!

Looks like there are two issues with these engines - HPC seal and combustor issues. Both are in the 'core'. Increase in feul effeciency led to trade off in something else??

I dont believe a word of that article.
Seems to be a tactic to know the logistics and fine print involved in Rafale buy. More importantly offset clauses and future options.

In the LCA thread there was a discussion on the 1 mtr plug for mk2 and how the entire certification cycle will have to be re visited. So applying the same logic here wouldnt the scorpene have to do the same if the proposed AIP upgrade plug after 6 years is being planned. Wouldnt it effect all the ta...

Once Scorpene subs enter service old subs will be decommissioned. We could use those. Its my guess kilos are not constructed modularly unlike scorpenes. Also its double hull.

If 3 more scorpenes are built at MDL with desi AIP and adding some MKI masala, it would be having a different signature. It would be painful to see yard idle after 2021. U209 redux.
