Landlord, your question is actually meaningless. The limits you say are only limited to what you know now, just like who would have thought that they would run more than 400 kilometers per hour when cars first appeared.
Engine power is an important factor in the speed of an aircraft, but it is not decisive. The flight of multiple blocks of an aircraft also depends on various factors such as its aerodynamics.
Different aircraft require different amounts of energy to fly up to Mach 3, so it's impossible to talk about how high the jet speed is. Just like the SR71, he can fly to other aircraft with the same engine, not even Mach 2.
With the development of industrial manufacturing technology, the development of crystal alloy and other technologies is also improving the bearing capacity of mechanical parts. So it doesn't make sense for you to say it in such a general way.
The engine is the heart of the machine, but it is not decisive. Just like a person with a good heart means that he is good at everything? Any machine is a whole, and there is no point in talking about something without the system.
Because you don't want a bare engine to fly there.

The turbofan speed can reach tens of thousands per minute... The jet speed must be greater than 3mA (depending on the local speed of sound) Fighter jets rarely do so fast... When it comes to mechanical parts, it's complicated.
After all, aero engines are arguably the most complex machines in human beings. With current technology, Mach 4 or 5 should be fine for missiles. If the pulse detonation engine test is successful, it will be a big improvement in aviation power.

Turbojet engine application jet propulsion avoids the weaknesses inherent in rocket and ramjet engines. Because of the turbine-driven compressor, the engine also has enough pressure at low speeds to generate strong thrust. Turbojet engines work in accordance with the "duty cycle".
It draws air from the atmosphere, compresses and heats it.

Before World War II, the combination of piston engine and propeller had achieved great success, giving mankind the ability to challenge the sky. But by the end of the thirties, the development of aviation technology brought this combination to the limit. When the propeller reaches a speed of 800 kilometers per hour, the tip of the propeller is actually close to the speed of sound, and the transonic speed and orange flow field make the efficiency of the propeller drop sharply, and the thrust does not increase but decreases.
The propeller has a large windward area and high drag, which greatly hinders the increase in flight speed. At the same time, as the flight altitude increases, the atmosphere becomes thinner, and the power of the piston engine decreases.
This led to a new jet engine propulsion system. The jet engine sucks in a large amount of air, which is ejected at high speed after combustion, creating a reaction force on the engine and propelling the aircraft forward.
Back in 1913, the French engineer Rennes"Lorrain proposed the design of the ramjet engine and patented it. But at that time, there were no corresponding means of boosting and corresponding materials, and jet propulsion was just a pipe dream. In 1930, the Englishman Frank Shed returned"Whittle was granted a patent for a gas turbine engine, the first jet engine design to be practical.
Eleven years later, he designed the first flight of the Bun Motor, which became the originator of the turbojet engine.

It can still greatly increase speed in high-speed flight.
Turbojet engine thrust is the resultant force of the air flow acting on the inner and outer surfaces of the engine, and it is an application of the principle of action and reaction when the jet engine is working.
Due to the work of the various parts of the jet engine, the air flow through the engine flows out of the engine at a very high speed, that is, the engine acts on the air flow through the engine with a large backward force, and this air flow gives the engine a reaction force, which is the thrust of the engine.
Precautions for turbojet accompaniment gas engines.
Generally, turbocharged engines have some special requirements for engine oil, such as oil viscosity, grade, coking performance, cleanliness, etc., if the oil that does not meet the requirements is used, it will cause abnormal wear or serious coking of the turbine, thereby damaging the supercharger.
Turbocharged engines must use high-quality air filters, and they must be replaced and maintained regularly. For areas with poor air quality, it is recommended to appropriately shorten the replacement cycle of the air filter. Always check whether the intake hose is damaged and whether the throat clamp is loose.
Let the remaining air intake pipeline be "solid and impermeable", and block all kinds of dust, impurities, particles, etc. from the air intake, so that the engine can breathe the purest air.

Compressor is an important component of turbojet engine, which transmits mechanical energy to gas and completes the gas working fluid compression process in the thermal cycle of the engine, so as to increase the gas pressure.
The increase in the pressure of the air entering the engine in the compressor is called the boost ratio, which is the ratio of the pressure of the compressor's outlet airflow to the pressure of its inlet airflow. Some engines are connected in series by one, two or three compressor units in sequence to form the engine's booster system, and the ratio of the pressure of the outlet airflow of the system to the pressure of the inlet airflow is called the total booster ratio of the engine.
Precautions for the use of jet engines.
Jet reaction is definitely an internal phenomenon. It is not as often assumed that jet engines are caused by the pressure of jet currents acting on the atmosphere. In fact, jet propulsion engines, whether rocket, ramjet, or turbojet, are designed to accelerate the flow of air or gas and expel it at high speed.
Of course, there are different ways to do this. However, in all examples, the final reaction force acting on the engine, i.e., thrust, is proportional to the mass of the airflow discharged by the engine as well as the speed of the airflow.

A jet engine is a reactionary engine that generates thrust through a jet. Most jet engines are internal combustion engines that work on Newton's third law. Jet engines in a broad sense include rocket engines and air jet engines.
The fuel and oxidizer of the rocket engine are carried by the aircraft, including the solid-fuel rocket engine and the liquid-fuel rocket engine code, which is characterized by being able to work in the atmosphere. Air jet engines, including ramjet engines, impulse engines, turbojet engines, and turbofan engines, draw air from the atmosphere as an oxidizer instead of carrying their own oxygen accompaniment. The most widely used air jet engine on modern air transport aircraft is the turbofan engine, which is characterized by high thrust, low noise, and low fuel consumption.

A jet engine is an engine that directly generates reaction thrust by the high-speed air flow from the nozzle. It is widely used as a power plant for aircraft. The fuel and oxidizer react chemically in the combustion chamber to release heat energy.
The heat energy is then transferred through the nozzle to the function of adjusting the airflow. In addition to fuel, the oxidizer carried by the aircraft is called a rocket engine, including a solid tung barrage fuel rocket engine and a liquid fuel rocket engine.
