Newspace is for dreamers. I've been involved with the Newspace community since 2011, and while the minds, ideas and passion behind this industry is phenomenal, the industry isn't so 'lucrative' and you know it yourself, if there weren't government support and backing, there would be no...

Really? Look at who Spacex's current sole customer is. Without it, there is no funding for private spaceflight programs. Also, have you seen Elon Musk's interviews? Your ego must be as big as his if you ignore how much hypocrisy is filled in your comment!

Not the point. Requirements in RFP's shouldn't change, and features of a design shouldn't change post critical design review stage. A second revision of a car is just a revision of features that enhance performance of the first revision, not a redesign from the ground up. During the 30 years...

A light aircraft has crashed on take-off near the airport in the Indian capital, Delhi, killing 10 people. The Beechcraft King Air plane chartered by India's Border Security Force (BSF) came down after hitting a wall in Dwarka district and burst into flames. The plane was carrying members of...

If you're faithful to the fundamentals and theories of science, I suggest you turn around and look away from these forums, as I am quite positive this is no place for 'intellectuals' like you. Besides, I don't think you'll be much missed, apart from Viets and a very few number of Indians who...

By the way, isentropic temperature ratio for a nozzle: T0/Te = 1+(Gamma-1)/2*Me^2 T0 = Stagnation temperature Te = Nozzle exit static temperature Gamma = 1.4 for air Me = Mach no. at nozzle exit If one assumes that the aircraft has a higher thrust, we can increase the exit Mach number...

My assumption, The silver is just special paint to reduce RCS. Wtih that being said, they probably installed a new engine, which works at a higher temperature at the nozzle, so the design team may have had to put in some time to effectively apply the new coating at high operating temperatures...

Really? It's been a while since I've take aerodynamics, but from what I recall, compressible flow revolves around the acoustic mach number, that is a=dP/d(rho), where rho is the change in density in a infinitesimally small boundary. So with an incompressible model which assumes rho to be...

Air India worker dies after being sucked into plane engine - CNN.com

Respect! One question, why only compressible. If one wants to test for ranges <M 0.3, I believe an incompressible model would be required also? In addition, then there is the transition zone or trans sonic region if you will, where turbulent flow really don't get represented well by the...

That's what I mean, sorry bad wording. I meant any subsonic round with a suppressor does the same thing really, sound wise.

Hahaha the link is broken... Your state military website is down?! LOL

Haha, I see I really did poke the stick onto a touchy topic, which got quite a few sensitive users here riled up. I don't see why you're bringing in Assad's support for Al-Qaeda here into the picture. To be honest with you, I didn't do a whole lot of research in it. However, I'd believe it...

Ballistics show that the .357 sig and the .45 acp are the most lethal per round to flesh. That is why special forces typically tend to carry these. Also, so long you're subsonic, your muffled sound won't make a difference whether you're using a 9mm, .45 acp. It's stuff like this that you can't...

Sorry, let's not use 'US.' I have a habitual saying of the 'US' when I mean Bush in particular. But then again, the US was under the presidency of Bush back then, wasn't it? In short, the American public wanted revenge for 911, Bush had his own oil agenda in Iraq. Just as Roosevelt swayed public...

Consider this also: The CCP intentionally allowed pollution from construction, and other sources to prop up and build up over the decades, in hopes of fueling the entrepreneurial spirit into investing $$ into chemical converters into non-toxic gases, anti-pollutants for construction, etc...

Sorry folks, just testing... Mods, please remove this thread, thanks! @waz

Sure, if you want to put in a global perspective, then the the yanks are the global aggressors, and you's are the regional bullies. Content now? Thanks for worrying, I verified my flags, and it's up to date.

Hello? The epochtimes anyone? The people who write that is clearly on some hardcore crack

Time to close thread. Why do you guys see a point in discussing? This is just a huge flame bait on both ends.
