If you're annoyed by inaccuracies and have a decent CPU, you can increase accuracy by using higher-order methods. For example, my parameters: Angular state: RK8 only, target substep 1.0 deg., max steps 180 Linear state: RK6 up to 1sec, RK8 otherwise Runs fine even on Celeron 3.00.

Specific Impulse is just a measure of effectiveness of a drive. That is, if you take an AMRAAM and an SRB, they'll have quite the same ISP - just because they're built on similar technologies. In numbers - it is just effective exhaust velocity, multiplied by coefficient of G. As for turbofans...

Hmm... Ive added the D component because just P was overshooting, and derivative addition almost eliminated this. Don't you confuse dervative (which IIRC eliminates overshoot) with integral (which eliminates steady-state error)? The latter, BTW, proved to be insignificant, so no need for I...

Well, talking about guidance... Here is a small test of the guidance module, built using PD control (thanks for pointing out, urwumpe). Currently properly works on Earth only. But with it missile (AIM-120) should be able to take targets maneuvering up to 9G (as a real one). Can anyone test...

Reading all this theories/prophecies and watching ignorant people believing in it makes me think Stalin was not so wrong sending charlatans into GULAGs. This is just another virus hype to market the film. With 99,99999% probability it will be discovered before it hits Earth ;) At least just...

Shuttle launch itself is not much of an interest, as Orbiter mainly deals with orbital operations. Moreover, orbinauts are usually not quite familiar with CA procedures, and we just don't have a Shuttle addon of such a high fidelity. However, we can think of cooperation in integrating whole...

What do you mean by "higher"? ;) What's better: to be detected at 10,000 km or at 10,000,000, considering an example weapons range of ~20,000-30,000 (quarter of a high orbit)? I'll personally choose first and shoot from 15,000... Also, the more powerful is the radar, the larger ARM will fly in.

Well, those who "established" it should be more accurate with their statements. Stealth doesnt' mean invisible. It means less observable than ordinary. That is, if "standart" spaceship has 1000m^2 RCS (Radar CrossSection here), a ship of same size with 10m^2 RCS (and that means detectable only...

Well, so magnetic levitation doesn't exist?.. http://en.wikipedia.org/wiki/Electrodynamic_tether Tether propulsion has even less thrust than ion drives. It's main advantage is lack of fuel consumption - a nuclear powered tehered satelite pair can theoretically stay in orbit forever even on LEO.

World "Universe" also suggests Earth with me and you sitting and discussing this topic, as well as our hard drives. Should we place \Windows\ directory there also?.. ;) Just no reason to have 1, 1\2 and 1\3 where you can have just 2 and 3. As a software engineer, I have to note: Vista has no...

I mean a function that parses e.g. 3ds file, writes it to temporary .msh and then loads by AddMesh.

A fairly rightful idea. Just some critics: I think, directory structure must resemble its contents, not some blurry characteristic. Not "red\round\ball", but "sports\billiard\ball6". So this should be easier: - Every 2-nd+ levelfolder represents an object. \Universe\Sol\Earth means Earth...

It's a demo of FlowVision, a professional CFD tool. I'm just evaluating possibilities now, but results are quite promising. Thanks, quite nice find.:speakcool: Though programs lack much, they can be quite useful for studying the principles. I'd even recommend to all the addon developers this...

Well, why not?.. _______________ Rep+ to anyone who guesses the craft and conditions:

Unfortunately, second guess is wrong too. Reading the posts again may help. Though there's little hope on it...

Release of own package containing components of someone else's is not "personal usage".

As long as permission is given. But your ethics are yours.

Though there's no license statement, I think, it would be unethical. But you can use something like that: http://www.freesound.org/packsViewSingle.php?id=1860 http://www.freesound.org/tagsViewSingle.php?id=126

Religion is people's opium, it eases their suffering Karl Marx Should we give kids methadone, so they don't take another drugs, or better bring them up not to take ones at all?.. We should thank the Church for it's short hands?..
