Currently blowing it is the fastest supersonic cruise missile and the only one on the planet during its voyage that breaks the sound barrier by traveling three times faster than sound waves and no known weapon system can intercept it due to its high speed, solid boost first stage or the solid booster powers the missiles and in the second stage featuring the jet drum engine we will learn more about this interesting engine in this article.
To understand ram jet technology we first need to understand the concept of shock waves everyone is familiar with the ripples created in water when an object is thrown into it these ripples move uniformly not now look at this interesting scenario suppose a boy is pulling tennis ball towards it, the movement of the source produces non-concentric ripples.
Isn't that interesting, the same effect can occur with sound waves during aircraft movement here sound waves replace water ripples and airplanes replace tennis balls, in this scenario the sound ripples will obviously travel at the speed of sound but here's a brain teaser for you what will occurs when an airplane is moving at the speed of sound.
Obviously sound waves won't be able to move forward so if you move with an airplane the sound waves will look like they are stuck in the front forming a sound barrier during world war two the sound barrier is considered an invisible wall because the plane has a high resistance but what if the plane moves more faster than sound waves.
The waves that are concentrated at the front of the plane will suddenly form a distributed ripple pattern as shown, the plane needs to apply more thrust during this transition also this distributed is conical the interesting thing is that the volume is very narrow with a thickness of two hundred nanometers and the temperature and high pressure builds up in this conical shape.
The pressure in this narrow region is almost twenty-nine times the regent atmospheric pressure. This is known as a shock wave. This is why a shock wave is formed when an airplane travels at a speed greater than the speed of sound. than the sound of the air volume which is shaded in red has absolutely no information about the disturbance caused by moving objects.
But in the green region the fluid disturbance occurs in the previous information, when the disturbed fluid suddenly interacts with the fluid particles in the red region that has no information about what is happening the shock will form at its boundary, the shock wave can cause damage to the human body but even though the wave This high pressure is a disaster there is a hidden opportunity in the middle.
Using the shock wave concept, let's understand how the feed engine works, the jet drum engine has a very simple geometry, it only has three main stationary parts, the filtered region at the entrance of the combustion chamber in the middle, and the nozzle at the exit, the task in the future is to increase the pressure. and the air temperature must be the jet drum will only work in supersonic conditions.
Because the flow is supersonic, scientists change the concept of shock waves to increase pressure in the future let's see how, shock waves are generated from many points of this cylindrical object, remember in a shock wave high pressure and temperature only exist in a narrow area but when many shock waves unite together -same something interesting happens you can see it delete a conical area will be formed without any shockwave effect at all.
This will be a low pressure area it is also clear that a high pressure conical wall will form in the territory of Indonesia, what about the remaining volume, to understand the condition of the remaining volume let's take a cross section of a cone with different lengths, you can see the shape like a flower if you add This number of flower cones will fill the entire area, remember the number of shock cones produced from the edge of the circle is unlimited.
The filling of this area applies to any length which means after the cone is empty at the beginning a thick volume of compressed air and high temperature is formed in the cylinder, in short it forms an automatic compression action with the help of a shock wave this is a ram effect of this high pressure and high temperature air can create combustion which is effective in the combustion chamber hydrogen is generally used as fuel for the engine ram then the combustion chamber increases the gas temperature and fluid velocity.
According to newton's third law, the greater the speed of the nexus jet the greater the thrust of the rocket, to further increase the speed of the jet, a convergent nozzle of the director general was added at the exit although this simple future arrangement achieves a very high pressure increase if the combustion pressure exceeds the limit then the forward section will explode causing the compressed air to spill out around the front of the tube.
This overflow limits the hair speed to one point two mAh, the scientists don't stop here they further enhance the spooky effect with the help of the aerodynamically designed inner body, in this latest amount you can see that the area allocated to the air actually decreases with the flow for supersonic flow when the arya decreases then the pressure increases in the jazz ram most of the pressure increase occurs due to the shock effect and due to a concept called oblique shock wave.
When the air hits the inner noise of the body it bends at several angles to form an oblique shock wave, this oblique shock wave hits the outer tube bends several times and is finally terminated by a normal shock wave.
In this method there is no air overflow because scientists were able to achieve high mah numbers for the chat room engine now let's learn more about the combustion chamber design of the chat room engine the speed of air flow through the ram jet is so high that the fuel mixing is complete in two to five milliseconds for perfect fuel mixing use an air flame retardant which helps to keep the combustion going it also stops the flame from going out by protecting it.
The most efficient hair in the speed range sorry three three point six, when moving at low speed the thrust is not enough to overcome the obstacles as a result the stand alone hair machine is not feasible to function, it takes a hard booster to propel the missile to supersonic speed, hope you enjoy the great technology usual from this ramzi machine before you switch don't forget to be a member of the lex team thank you see you next time.
