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.

What is nozzle less propulsion?
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.
What is nozzleless propulsion?
Propulsion by means of uniform cross sectional ducts rather than a varying section (nozzle) is said to be nozzleless propulsion
Why do rockets have nozzles?
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.
How do you freeze water without cold?
Pressurize it through a small nozzle. It will freeze at the nozzle.
What is the improtance of a rocket nozzle?
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.
What is the narrow opening at the tail end of a 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.
What are the two purposes of the nozzle in a rocket engine?
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).
What is the base word of propulsion?
propulsion makes something move forward,for example;airplanes have propulsion because without propulsion it would not move forward.
What is the definition of turbo jet engine?
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.
Where is the steering nozzle located?
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.
How do you measure gpm on a 2.5 in fire hose without a nozzle?
With a bucket and a stop watch.
How does a turbojet provide power to aircraft?
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.
