I. What is Ballistic Coefficient? The ballistic coefficient of a projectile is a measure of its ability to overcome air resistance in flight. In simpler terms, it is a numerical representation of how streamlined an object is as it moves through the air. The higher the ballistic coefficient, the more aerodynamic the object is, and … Read more
I. What is Spacecraft Propulsion? Spacecraft propulsion is the technology that enables spacecraft to move through space. Without propulsion systems, spacecraft would be unable to travel to other planets, moons, or even orbit the Earth. Propulsion systems are essential for launching spacecraft into space, maneuvering them once they are in orbit, and even changing their … Read more
I. What is a Centrifugal Fuel Pump? A centrifugal fuel pump is a type of pump that uses centrifugal force to move fuel from a storage tank to the combustion chamber of an engine. This type of pump is commonly used in rocketry to deliver fuel to the rocket’s engines at high speeds and pressures. … Read more
I. What is Roll? Roll is one of the three axes of rotation in aviation and rocketry, along with pitch and yaw. In simple terms, roll refers to the rotation of an object around its longitudinal axis. For example, when an aircraft or rocket rolls, it tilts from side to side, with one wing or … Read more
I. What is Solar Thermal Propulsion? Solar Thermal Propulsion is a type of propulsion system that uses solar energy to heat a propellant and generate thrust for a spacecraft. This innovative technology harnesses the power of the sun to propel spacecraft through the vacuum of space, offering a more sustainable and efficient alternative to traditional … Read more
I. What is Electric Propulsion? Electric propulsion is a type of propulsion system that uses electrical energy to accelerate propellant and generate thrust. Unlike traditional chemical propulsion systems that rely on the combustion of propellant, electric propulsion systems use electric power to ionize propellant and accelerate the ions to produce thrust. This technology has gained … Read more
I. What is the Oberth Effect? The Oberth Effect is a concept in rocketry that describes the increased efficiency of a rocket engine when it is fired at high speeds, particularly during a powered descent or a gravity-assist maneuver. This effect was first theorized by German physicist Hermann Oberth in the early 20th century and … Read more
I. What is Vulcan Centaur? Vulcan Centaur is a next-generation rocket developed by United Launch Alliance (ULA), a joint venture between Boeing and Lockheed Martin. It is designed to be a versatile and reliable launch vehicle that can meet the demands of a wide range of space missions. Vulcan Centaur is set to replace ULA’s … Read more
I. What is ULA Atlas V? The ULA Atlas V is a powerful expendable launch vehicle developed by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing. It is designed to deliver payloads into a variety of orbits, including geostationary transfer orbit (GTO), low Earth orbit (LEO), and polar orbit. The Atlas … Read more
I. What is a Bussard Ramjet? The Bussard Ramjet is a theoretical spacecraft propulsion system that was first proposed by physicist Robert W. Bussard in 1960. The concept behind the Bussard Ramjet is to use a massive magnetic field to scoop up interstellar hydrogen as fuel for a fusion reactor, allowing the spacecraft to travel … Read more
