Re: Indian investments thread

Guru log, what's your take on Tata motors for long term i.e. 5-10 years horizon? It has hit 52 week low twice and DVR is trading at 120 levels now. With their current/upcoming product lineup, I don't see any hindrance in Tata motors gaining the top spot.

Singhaji, high bypass turbofans efficiency stems from the way they generate thrust and their operating envelope. In commercial high bypass engines, 80% of thrust is generated by fan.

Re: Indian Autos Thread -2

If you ask me, the recurring issue with TATA is weight. There cars are heavy as compared to competition. For example Zest is 1135 Kgs, Dzire weighs 895 Kgs, Amaze 940 Kgs. This weight means low fuel economy though not by much. Zest Vs Dzire fuel economy differs by 1/2 Kmpl in city. But this weight a...

Re: International Aerospace Discussion

Why did it turn left before going down? Maybe it was not part of the schedule to go outside of the runway? Trainee tried to correct it by turning left but the momentum carried it beyond that point and IGE to OGE caused it to loose lift rapidly and before the situation could be corrected it crashed.

I don't think that there is enough space for jfs aft of MLG bay and beneath the engine. Moreover the only...

Re: New 3D arcade Game on IAF - Operation Morning Glory

Hi Sameer. Graphics are pretty impressive. The only let down are the controls. Instead of using the cursor position to steer the plane why not employ bank and pitch to turn? Once the plane is inverted, rolling only makes it skid to turn but the plane doesn't turn upright.
