In a neutral burn for a solid rocket, thrust does what over time? (increases, decrease, remains constant) Remains constant This kind of rocket is often referred to as the safest kind of rocket, combining both solid fuel and liquid oxidizer. Hybrid Rocket 00:54 01:25 In a progressive burn for a solid rocket, thrust does what over time? (increases, decreases, remains constant) Increases In a regressive burn for a solid rocket, thrust does what over time? (increases, decreases, remains constant) Decreases In a neutral burn for a solid rocket, acceleration does what over time? (increases, decreases, remains constant) Increases For solid rocket fuel, this kind of burn is also known as a "cigarette burn." A Neutral Burn Solid rocket fuel where the fuel and oxidizer are separate molecules held together with a binder is said to be what kind of propellant? Heterogeneous Propellant Solid rocket fuel where the fuel and oxidizer are chemically bonded together in the same molecule is said to be what kind of propellant? Homogeneous Propellant What are the four different kinds of chemical rockets? Monopropellant, bipropellant, solid, and hybrid Aerodynamic counterforce to solids moving through a gaseous medium is called what? Drag Describe the energy conversions in a rocket. Chemical Energy = Thermal Energy = Jet Kinetic Energy True or False: Solid rocket motors, ranging from the very large to the very small, span about 8 orders of magnitude pertaining to thrust force. True 00:00 01:25 True or False: Having a high initial speed in a rocket launch is important for both efficiency and stability. True True or False: In liquid rocket engines, due to extremely exothermic nature of the combustion reaction, engineers always solely rely on thick materials with high melting points to handle the heat. False: While the statement is true for smaller liquid engines, in larger ones engineers commonly run coolant around the combustion chamber (typically the fuel itself) to keep it cool. Specific Impulse (Isp) is a measurement of what? Efficiency (force / unit fuel / sec) When do we need a rocket? When we need (A) high thrust force and (B) there's an absence of a uniform medium (like atmosphere) True or False: Rockets consume very little fuel and are very efficient FALSE Rockets work following which of Newton's three major laws? Newton's 3rd Law (Every force has an equal and opposite reaction force)
