Re: Indian Space Programme Discussion

It is not so simple (that 6 seconds is enough) this relates to the initiation of the scramjet but remember that sustenance of the scramjet has also been a problem and the X51 indeed did not maintain its full flight duration fo 300 seconds and caused all sort of problems till they could achieve full ...

Re: Indian Space Programme Discussion

5 second ignition is indeed a huge success because it allows validation of initiation and maintenance of the function of the scramjet that allows further validation with all the data collected. The next test with data obtained will be of a longer duration.

Re: Indian Space Programme Discussion

Firing thrusters up and down is essentially mimicking the r bar approach to space rendezvous.Firing down will cause a higher orbit but slower velocity so the spaceship will move to a higher orbit but phase back. These are all stable circular orbits bring maintained. This is how orbital rendezvous is...

Re: Indian Space Programme Discussion

If you increase your tangential velocity in line you move up to a higher orbit.(and vice versa) The perpendicular velocity has to be imparted to go back to parking circular orbit.

Re: Indian Space Programme Discussion

The decrease in launches may be due to the monsoon. The scramjet test was delayed because of the searhc operations after the naval aeroplane crash.

Re: Indian Space Programme Discussion

There was some data from one of the periarctic countries (I think it was Finland) where they used the IRNSS data to determine acuracy and the area and range is much larger than what ids depicted because of the accuracy obtained by the data .

Re: LCA Tejas: News and Discussions

The Cobham probe has been itnegrated into it(There were photos of this probe integrated into the airframe). Now they have to do a dry run without contact to see the effect of wakes and turbulence while flying near the refueling tanker followed by dry lockon of the probe with the drogue and then actu...
