What is the force of thrust? What does thrust mean?

tuī lì]

Thrust. The force that propels the aircraft into motion. It is the resultant force of various forces acting on the inner and outer surfaces of an engine, or on a thruster such as a propeller.

In a propulsion system with a propeller, the propeller pushes the air to flow in the opposite direction of flight, and its momentum increases, creating a reaction force on the propeller, i.e., thrust. The propeller is often mounted in front of the engine, so it generates the force that pushes the aircraft forward, also known as the pulling force. The thrust of a jet engine is created by jetting a high-velocity air stream directly in the opposite direction of flight.

The maximum gas temperature of the engine directly affects the exhaust speed, in the general working state, the higher the gas temperature, the greater the thrust of the engine; The greater the mass flow of the working fluid through the engine, the greater the engine thrust. Under standard atmospheric conditions at sea level, the thrust generated by the engine when the aircraft is at rest is called sea level static thrust. The thrust produced by a rocket engine in a near-vacuum environment is called vacuum thrust.

In the case of an air jet engine, the thrust produced per unit mass of air is called unit thrust. The ratio of the thrust to the maximum cross-sectional area of the engine is called the thrust per unit area. The static thrust at sea level of modern airjet engines ranges from a few thousand N to 200 kN (1 kgf = N ) The thrust of a single rocket engine ranges from Ox to several megaN

Thrust includes two situations, one is the thrust of a person against an object, and the other is the thrust of an object against an object. Thrust in either case is elastic in nature. Continuing to classify the four fundamental interactions, elastic forces belong to the electromagnetic interactions in the fundamental interactions.

Thrust is an elastic force due to the force generated when the objects in contact with each other are deformed when they are extruded, and when the objects return to deformation. The essence of elastic force is that when the object is deformed, the distance between the molecules of the deformed part of the object (molecules in the physical sense) changes, and after the distance of the molecules changes, the gravitational force and repulsion between the molecules are unbalanced, so the gravitational force or repulsion force is generated between the molecules, and the macroscopic manifestation of this force is elastic force. The gravitational or repulsive force between molecules is generated by the action of electric charges between molecules, so it belongs to electromagnetic interaction.

It is an electromagnetic force, and all the forces acting due to deformation are electromagnetic forces.

Elastic force (subordinate to electromagnetic force).

Thrust refers to the force used to propel an object into motion, usually expressed as f, and the unit is Newton (n). It is calculated as follows:

f = m × a

where m represents the mass of the object in kilograms (kg); A represents the acceleration of the object in meters per second squared (ms).

When the object acting on the thrust is in motion, the formula f=δ(mv) δt for the thrust can be derived according to Newton's second law (f=ma), where v is the velocity of the object, δt is the change in time, and δ (mv) is the change in the momentum of the object. According to the law of conservation of momentum of the regression, the change in the momentum of an object under the action of an external force is equal to the action or amount of the external force, i.e., the thrust gained. Also, if the velocity of the object does not change, the formula degenerates to f = m g, where g represents the acceleration due to gravity, which is approximately equal to meters per second squared (m s).

It is important to note that the magnitude of the thrust is related to the mass and acceleration of the object, as well as the direction of the thrust and the time of action.

"Mobile phone thrust" refers to the minimum resistance that can push the earphone, that is, the minimum configuration current that can drive the Huai mode earphone.

"Mobile phone thrust" is not a professional term, each earphone has a resistance, when the mobile phone headphone jack comes out of the sound, there will be a driving force to transmit the sound, can push the connected headphone resistance to transmit the sound from the earphones to the ears, that is, when the mobile phone thrust is greater than the headphone resistance, the headphones will have sound.

"Mobile thrust" is similar to the power of a boat, the boat is on the water, and the power of the boat to go up is greater than the resistance of the water to flow down, and the boat can move forward.
