Nozzle-less propulsion refers to a type of propulsion system that operates without a traditional nozzle to direct the flow of propellant. Instead, it utilizes alternative mechanisms, such as electromagnetic forces or plasma dynamics, to generate thrust. This approach can potentially reduce complexity, weight, and increase efficiency in certain applications, particularly in advanced aerospace technologies. Research is ongoing to optimize these systems for practical use in spacecraft and other vehicles.
coz area is less thats y pressure is more
Solid motor propulsion works by burning a solid fuel mixture contained within a combustion chamber. When ignited, the fuel generates high-pressure gas that expands rapidly and is expelled through a nozzle, producing thrust in the opposite direction, according to Newton's third law of motion. The design allows for a simple, reliable, and efficient propulsion system, commonly used in rockets and missiles. Once ignited, solid motors cannot be throttled or shut down, making them suitable for specific applications where consistent thrust is required.
How to calculate the ratio of the inlet-to-exit area of the nozzle
My baby brothers baby bottle has a nozzle the size of an elephant!
The vena contracta is typically located at a distance of approximately half the diameter of the nozzle downstream from the nozzle exit. This is the point where the fluid stream reaches its minimum cross-sectional area and maximum velocity, following the contraction caused by passing through the nozzle. The exact distance can vary depending on factors like the flow conditions and the specific geometry of the nozzle.
Propulsion by means of uniform cross sectional ducts rather than a varying section (nozzle) is said to be nozzleless propulsion
A rocket nozzle is crucial for the efficient conversion of high-pressure gas into thrust. It accelerates and directs the flow of exhaust gases out of the rocket engine to generate propulsion. The size and shape of the nozzle influence the velocity and efficiency of the exhaust gases, impacting the overall performance of the rocket.
The narrow opening at the tail end of a rocket is called the rocket nozzle. It is designed to control the flow and direction of the exhaust gases produced by the rocket engine, allowing for propulsion and steering of the rocket. The shape and size of the rocket nozzle are crucial in determining the performance of the rocket.
In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
YES!! propulsion is possible without nozzles contributing in weight reduction and cost reduction. It is only possible when the mass burning rate of fuel/propellant in the duct is increased to that extent to reach the sonic speeds. more likely to be used in missiles and rockets.
To focus the controlled combustion blast of the ignited jet fuel, to achieve propulsion; and also to aim the force to alter trajectory (change direction).
Turbojets consist of an air inlet, an air compressor, a combustion chamber, a gas turbine (that drives the air compressor) and a nozzle. The air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
The steering nozzle is typically located at the rear of a watercraft, such as a jet ski or a jet boat. It is positioned where the water exit occurs, allowing for directional control by redirecting the water flow. In some systems, it may also be found near the propulsion unit, functioning as part of the steering mechanism.
The nozzle directs the blast from the burning fuel into a propulsion cone that is the most efficient for the engines output. Without a cone the flow of energy would be unpredictable and would not propel the rocket in the direction desired.
A turbojet consists of an air inlet, an air compressor, a combustion chamber, a gas turbine and a nozzle. Through this constructions, the turbojets provide power to an aircraft when the air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.
SR nozzle means "Self Reinforced Nozzle".
Spacecraft are propelled in different ways depending on their design and mission. Some spacecraft use chemical rockets for propulsion, where they expel propellant out of a nozzle to generate thrust. Other spacecraft use electric propulsion, such as ion thrusters, which accelerate ions to generate thrust. Solar sails can also propel spacecraft by harnessing pressure from sunlight.
