rocket propulsion final|2023 LATEST UPDATE|GUARANTEED SUCCESS
What are advantages of an end burning charge? Highest value of loading fraction What are the main component of solid rocket motors? Ignitor, casing and insulation, solid propellant grain, nozzle What are solid rocket propellant's classes? colloidal, composite, and CMDB What are properties of colloidal propellants? unstable, homogenous, can combust without other materials What are properties of composite propellants? stable, higher performance, better burn rate control that double based propellant, toxic, heterogenous What are properties of CMDB? better performance and storage than colloidal, less toxic that composite What is difference between stoichiometric vs. nonstoichiometric mixture of fuels? Stoichiometric has correct proportions for complete, while non-stoichiometric don't What does a liquid binder do? Hold compounds in suspension while they cure into a solid state Explain difference between end burning charges and radial burning charges. End burning charges burn propellant at one end and burn until completion at other end. radial burning charges burn propellant in radial direction. What are advantages of radial burning charges Provide high thrust and low burn time because simultaneous combustion of surface area What are two types of motor casing configurations? case bonded and cartridge loaded Difference between solid and liquid rockets Liquid propellant rockets more powerful, but require more valves to control performance What are some liquid rocket propellants? Monopropellants, bipropellant, cryogenic propellants, hypergolic, storable What are different feed systems for liquid rocket to supply thrust chamber with fuel mixture? Pressure feed or turbopump What are 4 different liquid rocket injection systems ranked from best to worst in terms of combustion efficiency? coaxial hollow, self impinging, unlike impinging, shower head What is purpose of liquid rocket injection systems? To introduce propellants into chamber so that stable and efficient combustion takes place What are advantage of hybrid rocket? Can be restarted and have higher specific impulse that solid rocket, oxidizer and fuel separated making safer, and better space allocation than liquid
