Chapter 1 - Introduction Flashcards
What does the, “Random House College Dictionary,” defines propulsion as?
“The act of propelling, the state of being propelled, a propelling force or impulse.”
What does the, “Random House College Dictionary,” defines the verb propel as?
“To drive, or cause to move, forward or onward.”
The “Random House College Dictionary,” defines the verb propel as, “To drive, or cause to move, forward or onward.”
The “Random House College Dictionary,” defines propulsion as, “The act of propelling, the state of being propelled, a propelling force or impulse.”
From these definitions, it can be concluded that the study of propulsion includes the?
Study of the propelling force, the motion caused, and the bodies involved.
Propulsion can be defined as the, “Study of the propelling force, the motion caused, and the bodies involved.”
What does propulsion involves?
An object to be propelled plus one or more additional bodies, called propellant.
What is the study of propulsion concerned with?
Vehicles such as automobiles, trains, ships, aircraft, and spacecraft.

What are methods devised to produce a thrust force for the propulsion of a vehicle in flight based upon?
The principle of jet propulsion (the
momentum change of a fluid by the propulsion system).
Methods devised to produce a thrust force for the propulsion of a vehicle in flight based on the principle of jet propulsion (the momentum change of a fluid by the propulsion system).
What may the fluid be utilized to generate a jet propulsion?
The fluid may be the gas used by the engine itself (e.g., turbojet), it may be a fluid available in the surrounding environment (e.g., air used by a propeller), or it may be stored in the vehicle and carried by it during the flight (e.g., rocket).
Classify the two broad categories in which jet propulsion systems can be subdivided into.
Airbreathing and non-airbreathing.
Jet propulsion systems can be subdivided into two broad categories: airbreathing and non-airbreathing. Describe the primary constituents of airbreathing propulsion systems.
Reciprocating, turbojet, turbofan, ramjet, turboprop, and turboshaft engines.
Jet propulsion systems can be subdivided into two broad categories: airbreathing and non-airbreathing. Describe the primary constituents of non-airbreathing propulsion systems.
Rocket motors, nuclear propulsion systems, and electric propulsion systems.
Since the engineering industry uses both the metric SI and English unit system, assert one singular distinction that exists between the English system and SI, thus separating them.
The unit of force is defined in the English unit system, but derived in the SI.
What does Newton’s second law of motion relates force to?
Mass, length, and time.
Newton’s second law of motion relates force to mass, length, and time. It states that?
The sum of the forces is proportional to the rate of change to the momentum (M = mV).
Newton’s second law of motion relates force to mass, length, and time. It states that the sum of the forces is proportional to the rate of change to the momentum (M = mV). The constant of proportionality is?
1/gc:
Sum F = 1 d(mV)/ gc dt = 1/gc dM/dt.
