Engineers and machinists at several U.S. Air Force bases are using NVision's HandHeld laser scanner to reverse-engineer complex aircraft parts, which are then machined to high levels of accuracy and installed, maintaining USAF planes in peak working condition. Reverse engineering is often required for aircraft that were originally designed without CAD systems and for which even blueprints can be difficult to obtain. The device is portable and can capture 3-D geometry from objects ranging from the exterior of an aircraft to extremely small parts such as an angle-of-attack sensor. The device is attached to a mechanical arm that moves about the object, freeing the user to capture data rapidly and with high resolution. The mechanical arm keeps track of the scanner's location so all data is collected within the same coordinate system. As a part is inspected, the scanner generates a point cloud consisting of millions of points, each with x, y, z coordinates and i, j, k vectors. Integrated software is used to convert the point cloud to an STL polygon, and an optional tripod provides complete portability in the field. Intuitive software allows real-time rendering, full-model editing, polygon reduction, and data output to standard 3-D packages.

Researchers from Purdue University are studying the fundamental mechanisms behind a method that uses electrical fields to enhance ceramics-sintering processing, which could aid R&D of rechargeable lithium-ion batteries and fuel cells. The research also could shed light on a phenomenon called electromigration, which can affect the performance of electronic devices.

France's Dassault Aviation and India's Reliance Group announced in late September 2016 the creation of a joint venture (JV) in India called Dassault Reliance Aerospace. With this announcement came news that the Dassault Reliance Aerospace JV will be a key player in the execution of offset obligations as a part of the 36 Rafale fighter jet purchase agreement that was signed between France and India on September 23, 2016 and is valued at around €7.87 billion, or about Rs. 59,000 crore.

One of the biggest issues in bringing forward new designs is the length of time that it takes to agree to a new specification, research and evaluate the alternative features and configurations, and then embark on a development program that will take the design to flight testing and ultimately operational service.
