There have been some mentions on this missile before and after also it could be assumed its a unbuilt missile project because it has not been declared operational or tested yet so here we go.

“The Russian military want to arm the Su-57 with a smaller hypersonic missile capable of fitting inside the stealth aircraft’s weapons bay, according to an aviation industry source cited by TASS. The alternative of fitting the large Kinzhal on a hard point, would have increased the jet’s radar cross-section.
The development of the new missile is part of Russia’s current military buildup program, which covers a period between 2018 and 2027, the source said. No details about a timetable for the development or the planned specifications for the missile were offered. The Defense Ministry would neither confirm nor deny the information.”

“A small-sized inboard fuselage hypersonic missile was developed for the Russian fifth-generation fighter Su-57, a prototype of ammunition was created. This was reported on Sunday by TASS sources in the military-industrial complex.
"The enterprises of the Russian military-industrial complex have created a prototype of a small-sized air-to-surface hypersonic missile for intra-fuselable deployment on a Su-57 fighter," said one of the agency’s interlocutors.
Another source confirmed the creation of the prototype and clarified that "the rocket has not yet been tested with the carrier aircraft." The interlocutors did not disclose the characteristics of the latest ammunition.
TASS does not have official confirmation of the information provided by sources.
In December 2018, another source in the defense industry told TASS that, within the framework of the state armament program for 2018-2027, the Su-57 is planned to be equipped with a missile with characteristics similar to hypersonic missiles of the Dagger airline complex, but with an inside fuselage."
Feasibility
Source From a User since I can't post the link:
"Now the Kinzhal is likely based off of the Iskander (mass of 3800kg) which has a diameter of 920mm. Based on the fact that the cockpit on the MiG 31 fits between the two engines and 900mm gives a reasonable amount of room for a pilot I'd say the Kinzhal is of similar diameter. Length wise from the image above if we measure the distance the missile takes up on our screen, draw a line of equal length, and copy and paste said line to fill the length of the aircraft, I found the missile’s length to be able to fit along the length of the aircraft 2.83 times meaning it is 0.35 times the length of the MiG 35; that works out to 7.98m.
The volume of a cylinder (which matches the profile of most of the missile’s length) is given byπ∗r2xhπ∗r2xh where r is the radius and h is the length. Yes the missile’s have a cone-like front section, but this rough calculation will give a value exceeding that of the missile and thus you will see a very generous amount, important to note if the range turns out to be short anyway.
Using the aforementioned equation the volume of the Kinzhal is 5.30∗106cm35.30∗106cm3. Since the weapon bays appear to be a rectangular prism we use v=l∗w∗hv=l∗w∗h
where v is volume, l is length, w is width, and h is height. That gives us a weapon bay volume of 2.48∗106cm32.48∗106cm3.
That means the volume of the Kinzhal must be reduced by a factor of 0.46.
The downscaled Kinzhal will have 0.19 the area for its rocket nozzle meaning the rate at which propellent is ejector is also cut by 0.19 (oversimplification again). That means that thrust goes down by a factor of 0.19 while mass decreases by only 0.46. The original Kinzhal would then have 2.4x the thrust to weight ratio of the newer missile. As drag is proportional to the cross sectional area the newer missile has 0.46x the drag of the original. That means the overall acceleration is 0.28 that of the original.
The optimum launch angle is 45 degrees (being generous again as the missile will probably not be launched at exactly 45, in fact it may be fired level with the ground and has to point itself upwards). They say that the kinzhal has a range of 2000km launched from the MiG 31 and 3000km launched from the TU 22; I fail to see how a simple change in launch platform increase the range by 50% so I’m just going to take the average of those two, 2500km. We will be even more generous and not take into account atmospheric drag. to calculate the total energy output of the missile. Using dx=(v2sin2a)/gdx=(v2sin2a)/g where dxdx is horizontal distance covered, v is velocity, a is angle, and g is the gravitational acceleration of 9.81 meters per second squared, we isolate for v to find the initial velocity. That gives us an initial velocity of 5000m/s (way more than the actual figure reported to around 3430m/s because of our generosity with these figures). Using Ek=0.5mv2Ek=0.5mv2 we get 47.5 GJ of energy. Since volume is proportional to mass the scaled down kinzhal will have 0.46x the mass and as long as it uses the same fuel it will have 0.46x the energy, 21.9 GJ. Converting this back into initial velocity gets us the same 5000m/s. Considering only 0.28x this value goes towards increasing the missile’s mechanical energy then the missile also has 0.28x the range.
Final verdict, the missile has a range of 690km give or take."

“February 23, 2020 Russian experts from NUST “MISiS” learned to increase the speed of missiles by adding copper to the fuel composition. As part of the tests, scientists were convinced that the copper nanoparticles in the fuel will significantly increase the efficiency (efficiency) of rocket engines.
For some time, scientists studied the effects of nano- and microadditives of aluminum, boron, zinc, nickel, copper and molybdenum on the burning rate of solid fuels. As a result, each of the additives showed a different rate of catalytic activity. For example, boron increased the burning rate of fuel by only 10%, and copper - by 500%.
As you know, at present, the so-called cyclic nitramines are used as combustible material in solid rocket fuel. However, these substances are quite resistant to the action of existing catalysts, which imposes a restriction on the burning rate of the fuel and, as a consequence, on the speed of the object. The search for new combustion catalysts for various types of jet fuel is a key task.
Researchers have proposed an alternative component composition of solid fuels. As a fuel, experts used aluminum powder, a catalyst - nano- and microadditives of aluminum, boron, zinc, nickel, copper, molybdenum and their oxides. It turned out that the addition of copper nanoparticles to fuel would increase the speed of rockets by a factor of five. The result of the study showed that copper increases the burning rate of fuel by 500%, zinc - by 130%, and boron - by 10% "
Multiply the thrust 0.19 back up to 500% or 5 times will give the new small missile almost the exact original speed but the same lower range would more than likely persist. Looking at russias R-73 and R-74 ranges and speed estimates, range increases from 300km to 500km going from ATACMS to PRSM shows we made improvements, Vikhr ranges to newer Hermes ranges has shown improvements as well.
Offer Similar Functions
Not Similar to the Kh-15 or black sparrow missiles but a possible similar function to these missiles

“It has a claimed range of more than 2,000 km, a speed of more than Mach 10, and an ability to perform evasive maneuvers at every stage of flight carrying both conventional and nuclear warheads”
http://rbase.new-factoria.ru/missile/wobb/iscander/iscander.shtml
“The 9M723 missile is a solid fuel, single-stage missile with a warhead inseparable in flight. The missile is controlled along the entire flight path using aerodynamic and gas-dynamic rudders. The 9M723 flight path is not ballistic, but controllable. The rocket is constantly changing the plane of the trajectory. It is especially active in maneuvering in the area of its acceleration and approach to the target - with an overload of 20 to 30g.
In order to intercept the 9M723 missile, the anti-missile must move along the trajectory with an overload two to three times higher, and this is almost impossible. Most of the flight path of a rocket manufactured using the Stealth technology and having a small reflecting surface passes at an altitude of 50 km, which also significantly reduces the likelihood of its destruction by the enemy.
Might Be Scramjet than Aeroballistic Missile
Brahmos-NG is said to offer the same range estimates as a previous Brahmos missile but with an increase of speed to mach 3.5 and a small size that is getting pretty close to fitting in aircrafts like the su-57. And I am assuming that the missile technology they keep for themselves is better than the missile technology they share with another country, Or Zircon having better performance than the Brahmos-2
Its believed that the same VLS will be used to launch the newer onyx variants which suggests the sizes will be roughly the same but a speed increase from mach 3 to mach 5 on another thread I have made in this forum.
Scramjets consist of a solid rocket booster to get the right speeds and altitudes for the scramjet engine to kick on next. The copper additives can give options to down size solid rocket boosters.
Zircon before had estimates of mach 6 and 500kms, Estimates were given to mach 8, estimates were given for mach 9 and than plans of doing this https://navalnews.net/russian-developers-to-increase-the-speed-of-zircon-missile-over-10-mach/ to stay at an altitude that is favorable for its flight.
Benefits To Internal Hypersonic Missiles.
Lets say there is a B-52 carrying an AGM-183 arrow or Mig-31 carrying a kinzhal and either one of them launch their missile from 3,000 kms.

Russia’s Su-57 may get ‘Kinzhal-like’ hypersonic missile for internal bay – report
The advanced Sukhoi Su-57 multipurpose jet may be armed with a hypersonic missile similar to the Kinzhal. Unlike the large already-introduced projectile, the future one will be small enough to fit inside the weapons bay.

Benefits To Internal Hypersonic Missiles.
Lets say there is a B-52 carrying an AGM-183 arrow or Mig-31 carrying a kinzhal and either one of them launch their missile from 3,000 kms.
- There is an altitude climb that can make it possible for radars to spot such a missile from 1000kms away.
- The long distance flight of 3,000kms for the missile will make it possible to warn that a missile attack is approaching from satellite infrared sources.
- Also hypersonic speeds form a plasma which causes disturbances in HF frequencies that can determine a hypersonic threat is on its way https://apps.dtic.mil/dtic/tr/fu....
- The B-52 and mig-31 with an external hypersonic missile carry will definitely notify other aerial units in case they fly by because they will have a very stupidly big RCS.
- And if they do happen to launch it 3000kms away from those aircrafts than their can be nearby mobile radar sources on land, sea and air using different frequencies will notice their is a hyper sonic object which is more than likely a missile, which more than likely suggests their is an attack underway.
- Infrared sources will have a more difficult time finding them.
- Nearby radar systems on land, sea, air will have difficulty finding them.
- Using LPI radar will make it difficult for passive sensors to identify them.
- Less possibility of being spotted by OTH radars because of launching hyper-sonic missiles at a closer distance without too much disturbance because of plasma.
- Significantly less reaction time for defense systems to realize an attack just happened before its too late.
- Internal weapon bay missiles will be very small, having smaller RCS and infrared signature than a bigger missile with same speeds.
- At-least 2 of them will be carried with a stealth profile.
