Compressor blisk parts of the LEAP engine will be manufactured by TEI upon the agreement executed by and between GE Aviation and TEI on September 26, 2013. Blisk parts at 5 different stages will be manufactured in accordance with the agreement, and 60 million dollar will be invested. It is anticipated that sales of 1.2 billion dollar will be achieved by 2035.
In addition to blisk agreement, TEI, which has proved its manufacturing and engineering capabilities upon completion of many "concurrent engineering" projects that it has launched together with GE and Snecma, has received manufacturing orders for more than 15 LEAP parts in line with itstarget; and such parts will constitute business volume of 170 million dollar based on the numbers of current engine firm orders for as of 2018-2019.
Blisk and spool parts with high geometrical complexity, which are started to be used recently in the new generation engines, are new practices for aviation industry. TEI announced proudly that it was one of the known companies in respect of the significant aircraft engine manufacturing technology throughout the world, upon execution of such agreement with GE Aviation. New generation LEAP engine symbolizes an important step in the aircraft engine technology in terms of fuel efficiency and cost effectiveness as well as of environmental factors. The fact that the blisks, which are the vital parts of the LEAP engines, will be manufactured by TEI is in compliance with the targets of strengthening the local manufacturing, and creating an additional employment area, and increasing the export capacity and competitive capacity of Turkey in respect of aviation products on a global scale, which are all included in the 2023 vision of Turkey. The biggest purpose of TEI in such project is to guarantee the business volume of more than 230 million dollar on annual basis through the LEAP engine, and to be the biggest supplier of LEAP engine part throughout the world.
The processes such as inertia welding, 5 axis airfoil milling, curved slot milling (CSM), electrochemical machining (ECM), Ultrapolish-airfoil surface quality enhancement, robotic surface treatment, etc., which require advanced technology, will be applied within the LEAP engine blisk project. The activities for determining the technical requirements of the equipment to be used during such processes, and process developments are in progress
