What are you talking about?
Even a dumb projectile can be fired at 1km/s, what we are talking about are projectiles with their own propulsion to add to the speed after they leave the muzzle.
please re-red again. I ws replying to your thesis bout 10 seconds work of engine.
A normal unpowered projectile like a standard 14.5 x 114mm round leaves the muzzle at 1km/s
With a scramjet motor on board providing forward thrust rather than slowing down as soon as it leaves the muzzle, over the first km it moves it might actually accelerate to 2km/s... so instead of moving 1km in one and a half seconds and the second km in 3-4 seconds... so 4-5 seconds to get to 2km range... it might get to the first km in less than one second and the second kilometre in less than two seconds because it is actually accelerating instead of rapidly decelerating...
that was precisely what I was saying.
GB wrote:If the scramjet can generate thrust for 10 seconds is way to ambitious... perhaps 5 seconds is more realistic with a powdered fuel burning in the airflow flowing through the projectile as it moves generating positive thrust initially for the first second or maybe two, and then just enough thrust to overcome drag and maintain speed at 2km/s, then in 5 seconds of flight it should manage 8-9km range at 2km/s...
IMHO it is too ambitious. With verge speed 1,5kms you travel 4 seconds 5-6km . Not whole path needs to be powered tho. imagine 1-2 seconds time. 2 seconds is lredy 3 km after muzzle while you still have high kinetic energy. I just wonder how they plan to make it guided? or it is wrong assumption? projectile is xtremly fast but not controllable. The whole smart-assnes is in ballistic computer?

Well they can bend or they can stand up... easy to say, not so easy to actually do. They should get a say in the next election, but that would assume those in power will let them have a say.
who is to stand up? 80 yo vets ? or hungry people with families? people are scared and hungry. in nazi run police state? in 2014 2nd my 40 people burned alive in trade union house.
BTW in Poland ow every low pid job seem to be taken by Ukrainians (like highway gas stations, services, cleaning ) . They're no nazis, normal people trying to survive collapse of own state. Although after say 6-8 months they speak Polish with only slight accent, so far none of them rejected to use Russian.
Form first hand - I've conducted testing . They were pretty happy somebody talking with them in their own language...
This elections can be interesting. Russian might not recognize new president or new president migh tbe not so pro US more pro Ukrainian.
