Yeah, length scaling means you non-linearly scale: Areas by exponent of 2 (i.e squared) Volumes by exponent of 3 (cubed). Creep is especially connected to areas getting squared by such scaling. Weight (mass) is directly connected to volumes getting cubed. Both among many others present...

From my experience at PW, these days we typically have anywhere around 100 to 1000 high level engineers involved during jet engine design phase (and the later deployment, support and optimisation phases) in these times. Each of these engineers can have sizeable number of mid level engineers...

reminds me more of a churchill with flamethrower trailer hehe

Depends on things like: A) Quantity and quality of the starting backdrop (RnD materials and database, previous experience in similar disciplines and projects etc) and research facilities...the more here, the less engineers needed. (i.e what do you exactly mean by scratch etc) B) How much time...

Reactor costs are pretty much the same (given enrichment of fuel and reactor design difference accommodating for that is very small portion of the final lifetime cost, if its even any different in the end). As to what those costs are like, I am unsure (given what gets allocated in funding to...

Thank you for the kind comments along with @Saithan and others. Folks can tag me if they would like comments regarding any other specific issues that crop up....since many follow lot of other places chit chat etc and they keep better track of such things. I'll try my best when I feel I can...

In wake of Indo-US nuclear deal (of mid 2000s), I remember the original plan (of project 75) was to acquire 12 hulls, 6 hulls from the West and 6 hulls from the Russians....with the view to make the next follow up project one that would combine the best elements from both. That never came to...

From AR-15.com @UkroTurk et al. Guys I owe an update after last few weeks of doing serious work for UA I’ve had a chance to talk to my normal friends in other less sexy brigades. So we sent a lot of help to a brigade recently sent to Bhakmut (Nov-dec) they did well and lost a couple dozen got...

Made me queasy just watching this

China will grow largeuh....we have BIG plans!

Off topic replies about war history etc have been moved to proper thread. Please continue discussion on that stuff over there. Thanks.

Like I get where you are coming from (though you did mention RCS earlier): Some IR signature angles would indeed be suppressed to some extent (w.r.t nozzle surface and maybe some portion of the plume) by having the vertical stabiliser fully adjacent (red) and a bit more aft, rather than...

There is no connection between where the vertical stabilisers are and "compromise of stealth" RCS reduction doesn't care about the surface being at X or translated to say X+5. It cares about the surface being as planar as possible and then as parallel as possible to other surfaces on the same...

It has nothing to do with the US being a Federal republic. It has far more to do with the separation of powers among the 3 branches of govt: Executive, Legislative, Judicial ...and how there are checks and balances organised between those 3 branches. It would be accomplished just the same if...

Looks more than big enough to me. Check out F-22 to compare.
