Inside the systems.

Move from the aircraft to an enlarged mechanism. Open its casing, separate its parts and select a component to learn its purpose.

Mechanism models are enlarged teaching exhibits, separate from the installed aircraft.

A SHORT EXPLORATION

From an aircraft to a fan blade.

Learn where components sit, what they do and how assemblies fit together.

  1. Select an engine.Click either engine on the aircraft, or choose it in Regions.
  2. Inspection opens automatically.The camera moves closer; surrounding aircraft remains visible and faded. Uncheck Show surrounding aircraft for an isolated view.
  3. Open the casing.Reveal the modelled internal geometry, then move Separate components.
  4. Select a module or blade.Click a part in Explore or Included parts / modules to inspect it and read its description.
  5. Reassemble and run.Return to the engine and run its rotors. Motion is deliberately slowed.

Orientation uses aircraft body axes: longitudinal x for roll, lateral y for pitch, and vertical z for yaw. Positive x is forwards, positive y starboard and positive z down. The axes remain attached to the aircraft; their screen projection changes as you orbit; the ground grid remains a visual reference. Separate mechanism exhibits use only Up and Down.

Engine flows opens an assembled engine with coloured routes. Animate or pause the markers, select a path to show it, and connect each route to a component. Separate components pauses and hides the routes until reassembly.

Systems labs opens signed flight controls and three enlarged mechanisms: a hydraulic actuator, oleo strut and multi-disc brake. Lessons open paused. Select a part, open its casing, then use the lesson controls to follow its movement. Hydraulic travel limits return the selector to neutral; applying the brake pauses the wheel display for inspection.

Calculations explores altitude and an ideal hydraulic press, with units, equations and reference examples. These calculations are separate from the prescribed 3D mechanism motion.

Use Up one level or the breadcrumb to return. Separation is a viewing aid, not a maintenance sequence. Touch: one finger orbits; two fingers zoom and pan.
POLYU AAE · UNDERGRADUATE LEARNING

A closer look at aircraft engineering.

Designed for Aeronautical and Aviation Engineering undergraduates in all years, this teaching preview combines an original generic twin-engine transport aircraft with selectable geometry and component explanations. It is an illustrative teaching design with simplified mechanisms.

Included in this preview

V0.4 refines cockpit glazing, landing-gear connections, wing structure, flap and spoiler mechanisms, engine construction and fuel conditioning. Flight controls show body axes, neutral outlines and actual surface deflection angles. Three enlarged, separate mechanism labs show a double-acting hydraulic actuator, oleo compression and multi-disc brake clamping. Select, isolate, open and separate their components. All lessons start paused. Engine flow routes and the checked standard-atmosphere and ideal hydraulic-press calculators are retained.

Learning across undergraduate years

The geometry and prescribed motion are simplified teaching models. They do not calculate aircraft response, hydraulic transients, landing impact or brake performance. Installed system networks, gear retraction, further mechanisms and lecture calculations remain in development; this preview is the starting point for a broader undergraduate learning atlas.

Sources and model information

Teaching references and original lecture identifiers are retained in the downloadable model inventories. They do not limit the intended audience. Geometry is originally authored for this project; no manufacturer model or livery is used. Source references do not imply endorsement.
