Overview of the Project:

In this project, controlling the retraction and extension of Airplane’s landing gear can be implemented using Finite State Machine (FSM). FSM is the most efficient algorithm which is mathematical model of computation.

Goals

• Controlling the direction of Valve.
• Controlling the retraction and extension of Airplane’s landing gear.
• Control of hydraulic pump for the
  landing gear

Key Highlights of the Project:

A direction valve is controlled by the software to allow the hydraulic pressure to either raise or lower the landing gear.

• Nose Gear
• Left Gear
• Right Gear

There is a hydraulic pump which is exerting pressure to the
gears to bring it down or pull it up and that pump is
electrically driven.

Deliverables of this project:

Implementing the control for the retraction and extension of Airplane’s landing gear using the Finite state machine with the knowledge of various states of switch and gear.

. A direction valve is controlled by the software to allow thehydraulic pressure to either raise or lower the landing gear

. Input for the Direction Valve

Expected Outcomes

The student will be getting the Knowledge of Finite State Machine algorithm which is used to achieve the control over the retraction and extension of Airplane’s landing gear using the switch and gear states of Airplane.

. Pilot’s Lever Rising && Squat Switch,Open / Lights = Green

.Pilot’s Lever UP / Direction Valve = UP,Lights = RED

.Limit Switch Closed /Lights OFF, Control for landing gear disabled
