FOUR NEW EXPERIMENTS / CONNECTED TO THE WHOLE LABORATORY
Build a flow from simple ingredients. Match a miniature experiment to a full-size aircraft. Discover two more routes to choking. Watch a rotor pass through its critical speed.
Each experiment pairs a visible mechanism with a stated mathematical model. Save one setup as A, change B, and connect the difference to the equations. No tests or scores.
01 · AERODYNAMICS / FLOW FOUNDATIONS
Drag elementary flow fields into place. Reveal their combined velocity, streamlines and pressure. Add circulation to an exact cylinder and examine the ideal lift.
Ideal incompressible, inviscid flow. Singularities are excluded; real drag, separation and stall are not predicted.
Build a flow ↗02 · AERODYNAMICS / EXPERIMENTAL METHODS
Move the test point towards a full-scale target. Match Reynolds and Mach numbers, then see how model size and balance uncertainty affect a synthetic force reading.
Algebraic similarity and an explicitly prescribed drag coefficient. Matching two ratios does not establish complete flow similarity.
Set up a tunnel test ↗03 · AERODYNAMICS / COMPRESSIBLE FLOW
A duct does not need to narrow to choke. Compare friction in Fanno flow and heating in Rayleigh flow, including the surprising response of a supersonic stream.
Steady perfect-gas branches with one effect at a time. The specified inlet solution stops at choking; the unsolved remainder is visible.
Explore friction and heat ↗04 · PROPULSION / ROTATING MACHINERY
Drag a correction vector, change the support stiffness and damping, then play a speed ramp. Compare the actual transient orbit with a settled constant-speed prediction.
A generic linear Jeffcott rotor. No real engine vibration limit, bearing fault diagnosis or maintenance instruction is inferred.

WHAT THE CHECKS MEAN
The numerical records include analytical limits, conservation identities and selected refinement tests. They establish consistency with the stated teaching models. They do not establish accuracy for a particular aircraft, tunnel or engine.
Choose a preset pair, inspect what is held constant, then change one parameter. Read the response and its limits together. A/B exports retain both configurations so a discussion can be reproduced.
