Rohit, higher wing loading is the biggest determinant of an "unstable" conventional aircraft which in turn is what defines maneuverability, including STR and ITR. Mig21 also excels in acceleration. Granted LCA has not touched its full envelope so far but expecting it to outdo the Mig with...

...However the Mig is heavier (due to older tech) but has higher wing loading (ie. has a smaller wing), giving it better maneuverability including ITR That is incorrect saar. ITR is highest at corner velocity, corner velocity is more quickly attained with lower wing loading. Corner velocity is the ...

Wire guidance does not guarantee they will not accidentally reacquire and target friendlies after having lost track of their original target, so even wire guided modern torpedoes self destruct if they cannot require. IIRC. AFAIK no one has put their threat libraries on munitions which may be recover...

Shalav

Like missiles torpedoes don't have IFF either... and like missiles they self-destruct when they fail to re-acquire their targets after having lost them to decoys. This is a safety measure to ensure they don't inadvertently target friendlies in the area, or even more unluckily the launching platform ...

The Standard 2000 was underpowered with its 2L inline, it was introduced late in the mid-80s after Maruti started to catch up with demand by the mid-80's and the waitlists were reduced to 6 months, about what PP and Amby's had at the time. It was expensive and underpowered. If they had offered it wi...

Shalav

No doubt Negi.

In desh, the ones who can afford the fuel expenses and big displacement engines, let their drivers drive BMW 5/7, Jags and Audi's!

While those who desire and yearn for good cars to drive, are driving the more affordable smaller displacement cars.

Shalav

If you've driven a petrol Amby and you just have to love big engines. There is no two ways about it. The Amby's engine was slow to rev up and torque was not so hot, but once it got going it kept on going on highways and anywhere. So much so, that Premier Padmini engines felt anemic compared to it. W...

The Maxima's always had better engines than the i4 Altima's (VQ series). The VQ IIRC is used on their Infinity brands in the G and M models and the Maxima and 3.5 l Altima's

Shalav

Yes - The Altima became the mid-sized Accord, Camry competitor, while the Maxima is classified as a full-sized car competing with the Toyota Avalon. The 7th gen Maxiam broke that trend and had IIRC 2" shorter wheel-base. I've driven it once or twice on test drives and it is a great car to drive...

Shalav

When you're next in the mid-west, you should drive the 6 Gen Maxima I have. The Maxima's reputation as a drivers car is not undeserved. The 7th Gen Maxima life is done this year and the 8th gen 2015 Maxima is due to be released soon. http://reviewcar2015.com/nissan-2015-maxima/2015-nissan-maxima-nis...

Aditya, I drive the SAAB mostly in mixed driving, highway and city, in this mode I get about 6.5 km/l. The SAAB is a fuel guzzler, but with the large 8 cyl engine it runs smoothly and I have power on tap at the press of the pedal, no matter what RPM the tachometer is showing. It is a trade-off I am ...

^^ It's all about the torque in naturally aspirated engines only saar! I must confess I like it that way too. I have driven a turbocharged Vdub Jetta and presently I drive a 5.3 litre SAAB 9-7 and a 3.5 litre Nissan Maxima. There is no comparison between naturally aspirated engines and turbocharged ...

Shalav

Perhaps it works in a similar way to the aerospikes on rockets - to reduce pressure drag?

Shalav

Sometimes simple explanations are really that simple.

Shalav

I don't think it was a coincidence that the Arihant sailed forth on the same day the IN and CG was deployed on more or the less the same line in the BoB for the launch and recovery of ISRO's CARE module. If there are subs there recording the Arihant "signature" the IN too is deployed recor...

The Russians have big parachutes. Big enough to drop artillery and light tanks. These weigh much more than the Soyuz capsule. What they didn't have was room in the Soyuz module to attach such large parachutes. Hence their solution was retro rockets. The Soyuz capsules are 70s tech, they are not fixi...

Shalav

You are correct, they've already tested flotation on SRE1.

When reinventing the wheel, why introduce unnecessary complications in the testing phase?

Shalav

Prasanna,

The capsule was not in the correct orientation for this TD . It was launched "upside down". The next test flights will have them in the correct orientation. Hence flotation devices, if added, will be at the boundary of the black and brown tiles.

Shalav

Landing velocity was reduced from the orbital 5km sec to around 2m/sec IIRC from the video.

On land touch downs the Soyuz capsule uses retro rockets

Shalav

Not wise to put flotation devices positioned so that the rest of the capsule is submerged including the crew hatch. That portion is the top of the capsule in normal orientation. It makes more sense to position the flotation device at the widest part of the bottom of the capsule around the boundary b...

The tiles look really good and do not look scorched like we see the Soyuz/Apollo and Shenzou reentry capsules. I cannot see the buoys/flotation devices.Wonder how it is floating. Floating because of displacement, like normal sea going vessels. Flotation devices were added to manned capsules after t...

Did he come back to apprehend him for robbery? Is that officer testimony or has it been corroborated by an independent source?

Evidence is like statistics. You can interpret any way you want. You are believing the cop side of the story and I am not. You do not know if the cop taunted him, or initiated the violence in the first place. There is no way to prove or disprove these things. But going by Officer Wilsons "demo...
