Aerospace Engineering

← Back to Domain-Specific Abstractions by Domain

2 domain-specific abstractions whose origin domain is Aerospace Engineering.

  • Perifocal Coordinate System — A focus-centered right-handed orbital frame whose P-axis points to periapsis, W-axis follows specific angular momentum, and Q-axis completes the orbital plane, making Keplerian state vectors simple functions of true anomaly.
  • Vehicle Axes Conventions — Standardize a vehicle’s reference-frame origin, axis directions, handedness, attachment, and positive motion signs so positions, attitudes, forces, and rotations are interpreted consistently.
