EIGHT EXPERIMENTS · ONE CHAIN OF CAUSE AND EFFECT

Change the event.
See what follows.

Trace the connections between shape, energy, measurement and control. Move an event in time, save a reference and watch two responses unfold together.

01 / Configuration, power & measurement

Aerodynamics & Fluid Mechanics

High-lift Devices & Configuration

Move the flap. Rebalance the aircraft. Watch lift capability, drag and tail load change together.

Open experiment ↗

Aircraft Systems

Hydraulic Networks & Actuator Dynamics

Follow a pump, accumulator and position servo through a command, a pump loss and a backup response.

Open experiment ↗

Aircraft Systems

Electrical Power & Load Management

Lose a source, connect the buses and shed demand. See which loads remain supplied and how the battery reserve changes.

Open experiment ↗

Flight Dynamics & Control

Air-data Faults & Control Response

Compare true motion with sensed motion. Introduce a pressure-source fault and watch it enter the feedback loop.

02 / Near-ground flight & flexible wings

Aircraft Performance

Ground Effect & Landing Flare

Set a flare event and compare the same approach with and without the ground. Follow height, speed and lift together.

Open experiment ↗

Aerodynamics & Fluid Mechanics

Flexible Wings & Aeroelasticity

Inspect coupled bending and twist, then switch to a typical-section flutter experiment with an unsteady aerodynamic wake.

Open experiment ↗

03 / Engine response & cabin demand

Propulsion & Engine Systems

Engine Acceleration & Compressor Stability

Follow the rotor energy during acceleration, then inspect a separate compression system where duct inertia and plenum storage can produce surge.

Aircraft Systems

Bleed Air, Cabin Cooling & Engine Performance

Allocate engine air to the cabin. Trace the heat removed, the pressure maintained and the propulsion consequence.

These experiments extend the existing topic modules. Their original chapters remain available. Each experiment states its equations, assumptions and stopping limits.
