Transparencies Optical Inspection

 

New version of the Topins has been released

topins logoDecember 8, 2014. We proudly present new version of TOPINS LIGHT standalone application! We have release completely new standalone TOPINS Light application which doesn’t require database neither any additional information except pictures for testing so this makes it very simple to use and easy to maintenance.

The features in the new TOPINS standalone application are:

  • No database required: Results of the testing are saved localy on your computer where ever you want. No database costs and no database maintenance required
  • No project information required: You can simply start new test without any purchase order, project or any other information required. This version excludes document management.
  • Very simple to use: You just have to provide pictures for testing, choose standard and that’s it! Only few steps are required to test transparency and generate results that will provide information about transparency optical quality.
  • Reporting tool: You can still generate reports and results with as many information as you want but now they will be saved localy on your computer on any chosen location.

TOPINS Version V5.0 Release

topins logoOn May 19, 2014, Cad Professional Systems released TOPINS Version 2014 Release 5 (v5.0). V5.0 Version offers complete client-server arhitecture for multiuser environment that provides uniqe database and strong document management system. Transparency analysis accuracy is increased to 1:30 and higher, depending on the hardware limitations.

 


TOPINS - New Software Solution for Aircraft Transparencies Optical Quality Inspection

TOPINS is a complete and unique software package which provides fully automatic, very accurate, reliable, efficient and flexible calculation of a key transparency quality parameter – distortion.

Non-uniform thickness of a transparency, excessive curvature of a transparency, heat-induced stress, structural stress generated during the installation of a transparency into the canopy frame and the installation of a canopy on the aircraft are the most common causes of transparency distortion. Objects viewed through a distorted transparency can be magnified, lengthened, or misshaped, their movement can be misjudged, etc.

Distortion (distortion effect is enhanced)

How is distortion usually measured today in the aircraft transparency industry? Transparency distortion is usually measured directly by the manufacturer, in specially equipped rooms. A typical apparatus for measuring distortion consists of a grid board, a digital camera and a stand for fixing the windshield/canopy that is to be examined. In order to measure the distortion, it is necessary to put the camera in the position equivalent to that of pilot’s eye and make a picture trough the transparency.

By visually examining the captured image(s), the inspector locates the region with clearly apparent distortion. In that region, the angle of tangent slope in a portion of deformed grid lines has to be calculated (the slope for both horizontal and vertical lines should be calculated) and then compared to the adequate standard.

Distortion has been measured in this way virtually since the dawn of the aircraft transparency industry! In practice this method has been shown to be slow, inefficient and highly susceptible to subjective interpretation by all links in the quality assurance chain, from the transparency manufacturer to the pilot as the end user.

Our TOPINS software package has been developed to meet the highest standards of quality assurance in transparency inspection and to fully eliminate any subjective factors from the process. TOPINS is the result of many years of dedicated work by leading MECAPLEX experts on aircraft transparencies optical quality inspection, computer image processing experts, IT engineers and aircraft engineers.

 
 
TOPINS - distortion measured on windshield 


Use of TOPINS software allows manufacturers to introduce an effective and uniform distortion inspection mechanism, compliant with any standard that may be specified by the customer. Implementation of this software does not require any modification of the existing system or any additional investment in equipment. A very powerful PDM system, which is included as a feature of TOPINS, provides full support to the quality assurance department (purchase order/contract tracking, storage of technical documents, recording and monitoring of geometric parameters of transparencies, statistical view and quality monitoring over a specified interval, search by all relevant parameters, certificate generation...)

For end users of transparencies (aircraft manufacturers and servicing organizations), TOPINS is a highly reliable and efficient tool for internal transparency distortion inspection through all lifecycle stages of the product – from quality inspection at the time of acceptance from the manufacturer to in-service inspection. Thus, potential users of this solution include transparency manufacturers, manufacturers of civil and military airplanes and helicopters, repair and overhaul facilities...

TOPINS is a stand-alone Windows application enabling high-precision automated and/or manual distortion measurement across the entire visual field of the transparency. Distortion is measured according to one and/or multiple selected standards. A feature of TOPINS software is also the PDM system, which manages all relevant data and technical documentation relating to the examined transparency.
