The FLASHJET Coatings Removal Process is a synergy of several coordinated sub-processes, all finely tuned, to remove coatings at a controlled rate:

FLASHJET Process

Important features of the FLASHJET Coatings Removal Process include:

bulletIntegrated Stripping Head
bulletSingle-Point Process Control
bulletProcess, Motion Control, and Safety Sensors to Protect the Aircraft
bulletSelective Stripping - Can Remove Top Coat Only
bulletReduced Operating Costs (more operating cost data)
bulletSafe for Metallic and Composite Substrates
bulletLow Volume of Residual Effluents (more on environmental features)
bulletMinimal Safety Requirements

Xenon Flashlamp

As the FLASHJET stripping head moves across the surface of the aircraft or an aircraft component, a powerful xenon flashlamp is pulsed, ablating the coating.

CO2 Dry Ice Particle Stream

Simultaneously, a low pressure (15 lbs/in2) dry ice particle stream cleans and cools the surface.

Effluent Capture

The resulting combination of fine particle paint ash and gases - called  effluent - is pulled away by a vacuum system, through pre-filters, HEPA (High Efficiency Particulate Air) filters, and a carbon bed tub scrub, resulting in a clean air output.

Robotic Control

Robotic Control involves execution of pre-defined Stripping Programs that have surface contour, path and index direction, and boundary information for an area of an object.

Features of Robotic Control include the following.

bullet

Teaching Strip Path Programs is a one-time task.  Once taught, they are recalled for re-use.

bullet

Standoff Sensors are used to assist with the teaching process, and can also be used during stripping, to maintain normalization or just standoff distance.

bullet

Automatic Motion Control Safety monitors for:

bullet

Collision Detection,

bullet

Robot In Motion, and

bullet

Pass in Progress

If any one of these signals is lost the stripping process immediately stops.  If a collision is detected, robot motion stops.

bullet

Operator Stop/E-Stop Overrides.  At anytime the operator feels uncomfortable about robot motion, he/she can stop the robot by pressing numerous stops and E-Stops available on the Process Controller, Teach Pendant, and throughout the workspace.
