KC390 cargo door and ramp door installation system – Multipurpose vehicle
- Client: EMBRAER
- Country: Brazil
- Start date: 2014
- Ending date: 2015
SENER successfully developed the door installation system for Embraer’s KC390 military aircraft.
It is a multipurpose vehicle and can be used to assemble and fit several parts of a plane, such as the doors (cargo, ramp, etc.), wings, cockpits, sections of fuselage, tail cones, engines, pylons.
The system incorporates a manually guided vehicle with two sets of motorized wheels with omnidirectional capacity and a positioning accuracy of ±1 mm.
A hydraulic lifting system includes a stiff lambda scissor and a multiple scissor, to lift up to 5 tons to a height of 5 m, with a slope of up to 20 degrees.
Having approached the aircraft at a safe distance, a fine positioning system is activated, which is integrated into the upper platform of the lifting system. The fine positioning system provides an additional 6 degrees of freedom for handling an aircraft’s parts, with a +/– 0.1 mm accuracy along the 6 degrees of freedom and a 100 to 200 mm pathway along the three axes.
The system’s upper platform incorporates a reconfigurable interface for aircraft parts of different sizes and aerodynamic surfaces. The interface can be automatically and quickly activated to support each of the pre-configured products.
For final fine handling when assembling parts, the operator can be helped by a floating system incorporated into the upper platform.
The lifting system, the fine positioning system and the floating system are controlled from a programmable WI-FI touchscreen. This touchscreen tells the operator each step to follow in the assembly process, and their respective safety conditions.
The omnidirectional vehicle is controlled by a double-joystick console. A SCADA indicates the DIAGNOSIS during the parts handling procedure.
