Cryogenic rocket-engine-propellents
Cryogenic rocket engines use cryogenic, or very cold liquefied gases, as propellants. They are typically fueled by liquid hydrogen and liquid oxygen which must be stored at temperatures below -423°F and -297°F respectively to remain in liquid form. Cryogenic engines offer advantages like being able to control and restart the fuel flow, but require complex turbopumps and thermal insulation to handle the extreme cold temperatures. Major components include thrust chambers, fuel injectors, turbopumps, igniters, valves, tanks, and de Laval nozzles. The Space Shuttle's main engines were cryogenic, using this technology to produce high exhaust velocities and thrust.

Cryogenic Rocket Engine
It tells about what is a Cryogenic Rocket Engine , its's brief history, construction how it works and future aspects.
Very-high-Temperature Reactor
Very-high-Temperature Reactor (VHTR) is a type of high-temperature gas-cooled nuclear reactor that can operate at very high temperatures, over 1000°C. There are two types: pebble bed reactors consisting of fuel spheres arranged like a gumball machine, and prismatic block reactors with stacked hexagonal graphite blocks. VHTRs use coated particle nuclear fuel and a graphite moderator, with either helium or molten salt as coolant. They have advantages like higher electric efficiencies over 50% and ability to produce hydrogen, but also disadvantages like limited research and low thermal conductivity of helium coolant. Future research areas include improving high temperature fuels and coatings, and developing new
Rocket propulsion report (2)
Rocket engines produce thrust by accelerating and ejecting stored propellants at high speeds through a nozzle. They obtain high thrust-to-weight ratios but have the lowest fuel efficiency of all jet engines. Key components include the combustion chamber, where propellants combust at high pressures and temperatures, and the supersonic nozzle, which converts the hot gas energy into kinetic energy of the exhaust jet for propulsion. Rocket performance is optimized by maximizing exhaust velocity and specific impulse through high combustion temperatures, low-mass propellants, and nozzle designs that adapt to changing ambient pressures.
Cryogenic rocket engine
Cryogenic rocket engines use cryogenic (very cold) liquid fuels like liquid hydrogen and liquid oxygen that are stored at extremely low temperatures. They provide several advantages like high energy density and clean, non-polluting exhaust but also have challenges like boil-off losses and material compatibility issues. The document outlines the history, construction, power cycles like gas-generator and pressure-fed, combustion process in the thrust chamber, and advantages and disadvantages of cryogenic rocket engines.
Unit v rocket propulsion
This document discusses rocket propulsion and solid rocket motors. It defines propulsion as initiating or changing the motion of a body. Rocket propulsion works by ejecting propellant to create a reaction force and induce motion. Solid rocket motors use solid propellants composed of fuel, oxidizer, and binder. They provide high thrust but have low control and cannot be shut down and restarted. Performance is measured by parameters like specific impulse, total impulse, and effective exhaust velocity.
Cryogenic Rocket Engine
Cryogenics is the study of the operations at very low temperature (below −150 °C, −238 °F or 123 K) and the behaviour of materials at these temperatures.
rocket propellants
Rocket propellants can be either solid or liquid. Solid propellants store fuel and oxidizer together in a solid casing, while liquid propellants store fuel and oxidizer separately in tanks. Liquid propellants provide higher efficiency but require complex pumping systems, while solid propellants are simpler but provide lower efficiency. Rocket performance is measured by specific impulse, with higher values indicating more thrust per unit of propellant. Careful fuel measurement and propellant mixing ratios are required to achieve optimal rocket performance.

knock sensor
Knock sensors detect knocking or pinging sounds in an engine caused by low quality fuel, deposits, or incorrect spark plugs. The sensor uses a piezoelectric element that generates a voltage when pressure or vibration is applied. When knocking is detected, the sensor sends a signal to the ECU to slightly retard the spark timing to prevent damage. Knock sensors allow for more efficient engine performance by allowing the engine to operate closer to the detonation limit.
