Yasen submarines to be equipped with hypersonic missles with 1000km range

Seriously dude,Are you joking????

This is bullshit Physics.

A flying object needs 1G of lift to stay in the air. Divide 1G by the lift-drag ratio and you get the amount of thrust-weight ratio that the missile has to maintain to keep going. Fuel consumption is proportional to thrust. At least as a first order approximation, fuel consumption rate is constant regardless of how fast you fly. Thus, the flight time of the missile is a function of fuel fraction. By flying faster during this flight time, you go farther.

It's simple physics, and it's absolutely correct.

Obviously, going faster while generating only 1G of lift without lowering your lift-drag ratio requires you to fly at higher altitude, where the lower density makes up for the higher airspeed. But a hypersonic scramjet can do exactly this.

The real problem is making a scramjet that compares in efficiency to an ordinary turbofan or turbojet. Obviously, this is no easy thing. But there is nothing in basic physics that rules this out.

That is exactly what is called as bullcrap and misrepresenting science to suit your agenda.

An flying object requires 1g of vertical acceleration to remain steady.

If an object is moving in a vertical plane it has to accelerate more than 1g.The drag force is proportional to square of velocity and as the velocity of missile increases,drag force on missile increases.An hypersonic missile attains more velocity then a supersonic one.The missile has to exert more force to overcome air drag.Thrust requirement of a hypersonic missile is more not only because of higher acceleration that the missile would be have to partake but also because it has to overcome much more air drag compared to a supersonic missile.

In it's flight mode,a missile not only have to apply a force of vertical force of 9.8m[SUP]2[/SUP] to remain aloft but also has to apply an horizontal force whish is proportional to square of velocity

.Velocity of hypersonic missile is more than that of supersonic missile thus is a direct deduction from common sense that drag force being applied on an Hypersonic missile would be more than that of supersonic missile.Thus more thrust force would be required in case of hypersonic missile than that of supersonic one.


The thrust could be increased by following methods

1.By increasing the amount of propellent in a missile.This would lead to lower thrust/weight ratio.Increase in weight also increases the thrust required for acceleration of missile and could not be taken up if there are size constrains.

2.By increasing the efficiency of propellent.Very difficult.

3.To increase the efficiency of Engine.Most probable.

This is simplest of physics of motion of a body in fluid.

As the missile moves forward,it would use up fuel thus reducing it's weight.The missile would require lesser thrust to accelerate but it would not lead to reduction in drag force acting on it.The missile if moving at constant spped would require to produce same amount of thrust.

PS.Do not think that everyone else except you is stupid.You ignored a lot of variables in your assessment and tried to slip through using confusing jargons and self contradicting statements.

LOL

Scramjet engine is an air breathing Engine,it is not a rocket engine that could escape atmosphere.It needs to remain within stratosphere thus air drag cannot be neglected.

And anyway even in vacuum,Hypersonic missile would require more fuel than supersonic missile thus having more weight.

Consider that a missile is fired in vacuum.Thus air drag is not acting on that missile.Now compare a supersonic missile with a hypersonic one for same range.

The thrust required in this case by a missile would have zero horizontal component and would be equal to weight of missile in vertical direction when it is in cruise mode.Thus both missiles are equal on this front.But for these missiles to attain their respective velocities which in case of hypersonic is higher than supersonic,the hypersonic missile would require higher acceleration for same amount of time or similar acceleration for extended time.If the missiles are using same engine,hypersonic missile would require more fuel thus increasing it's weight.

The real problem is making a scramjet that compares in efficiency to an ordinary turbofan or turbojet. Obviously, this is no easy thing. But there is nothing in basic physics that rules this out.

The real problem with scramjet engine is that in order for scramjet engine to start,the body need to be travelling at supersonic velocity.Along with that a scramjet has lower thrust/weight Thus one always need to strap booster rocket to a missile in order to start scramjet.Efficiency of scramjet has to be compared with rockets as turbofan or turbojet engines are incapable of attaining hypersonic speed and scramjet engines come out with flying colours in that comparision because Scramjet engines does not have to carry oxidiser thus reducing their overall weight.

Holy macro.. this is a beast. And 600 m underwater nobody will know it ever there. Kill the Carrier from down under.

Its simply basic physics, no need to be a guru. With speed increase fuel consumption is growing exponentially. Thats why 7 ton Granit has range of 550 km and 3 ton new Brahmos/Oniks - only 300 km and bot missiles are only supersonic. Also Granit is way too big for Yasen class submarine.

Here we go with Israeli physics :lol:

S-400 missile 40N6:
Range: 400km
Speed: Mach 12
Weight: 2 tons

Looks like designers of S-400 are not aware of Israeli physics :lol:

Air to air missiles are different story, because u can very reduce missile size by reducing warhead weight. With direct hit u can destroy the aerial target without warhead at all.

For example 48N6E missile of S-300 has 145 kg warhead, while new 9M96E2 missile of S-400 has 24 kg warhead. US THAAD and SM-3 dont have a warhead and use direct hit.

Thats simple rocket equation:

In case of ASM u cant reduce weight of warhead drastically.

Secondly whats source of your data? It sounds BS nevertheless.

Russian have the best G to G, G to S, S to A , and A to A missiles and systems in the world in terms of range, maneuverability, portability, war-heads,guidance, and resistence to anti-missile systems and jamming.

Oh yeah? Size of warhead? So Granit uses 5t warhead thats why its weight is 7t compared to 40N6's 2t? Or not? :lol:

Oh, lets compare warhead size
40N6: 200kg
Brahmos/Oniks: 250kg

Oh, i see. If we increase warhead of 40N6 by 50kg this missile suddenly will became bigger than Granit? Or not? :lol:

You seem confused. Maybe there some other things besides warhead size that could affect weight and size of missile, that your Israeli physics is not aware of, did not you think about it? :lol:

You are again comparing incomperable. Granit is cruise missile, 40N6 acts as ballistic missiles at max range.

Anyway 12 mach speed, 200 kg warhead and 400 km range in 2 t missile is impossible thing to do for both cases.

Ah i see you continue to make up things and fantasizing here. 40N6, which is designed to hit maneuvering supersonic targets, is now act as ballistic missile :lol: i wonder what you will make up next?

Thats basic fact. Long range s-a missile have ballistic trajectory. Their engine works only for some 10-15 seconds accelerates missile to 2 km/s and then shuts down. 80-90% of range they fly using only inertia. So they are basically maneuvering ballistic missiles.

Cruise missiles like Granis and Brahmos use engine till impact. Congrats u learned something new today. :)

:lol: 40N6 is surface-to-air not air to air missile do you even have a clue what u r talking about? :lol:

I meant surface to air, spell mistake. Long range a-a also have ballistic trajectory though.

a-a missile can have whatever they want, wtf this have to do with 40N6?

so surface-to-air missiles now are using ballistic trajectory? :lol: ok but what prevents Brahmos or Granit from using such trajectory then?

Brahmos and Granit use engines trough all their flighttime, thats why they are cruise missiles. Brahmos has lofted trajectory mode which increases range from 120 to 300 km though.

What makes you think 40N6 acts as ballistic missile?
What makes you think 40N6 dont use engines through all its flighttime?

If Brahmos use "lofted trajectory to increase range" whats ur problem with 40N6 using any possible trajectory to increase its range?

How much more BS you are going to make up? :)
