Our product range extends from various engine components to blades, discs, blisks, housing and structural parts. Here, it is not only the quality that matters, but also the use of economical manufacturing processes.
That is why we offer our customers solutions with maximum efficiency:
Starting with the order of the raw material through to the delivery of the ready-to-assemble parts. In order to guarantee high quality and maximum efficiency, we are constantly working on continuously optimizing our processes.
We are a partner for all renowned OEMs and module suppliers in the aircraft engine industry.
Our core business is the manufacture of engine blades, discs and components.
With our safety-relevant components we make a big contribution to the aviation sector: Today, modern aircraft engines use components from Turbine Technology throughout the world.
In cooperation with our customers we push the technological progress in order to achieve future market requirements for high-quality components.
Aero engine airfoils
Leistritz has been a partner for aircraft engine manufacturers since the very first jet engines, helping develop and manufacture turbine airfoils from extremely tough materials such as high-temperature steels, titanium and nickel-based alloys. Leistritz Turbinentechnik supplies such airfoils as either forged blanks or ready for assembly.
The focus is clearly set in the field of compressor airfoils. The precision and dimensional accuracy of the compressor airfoils are decisive for the power and output of an aircraft engine. This is why the manufacture of the aerodynamically-shaped, complex airfoils geometries with the narrowest of tolerances is a particular challenge.
Aero engine disks
The demands on disks in modern aircraft engines are growing steadily. An increasing efficiency calls for higher temperatures in aircraft engines and thus increasingly better materials that are usually difficult to forge. Our production program covers all rotationally symmetrical aircraft engine components such as full disks, rings, shafts and cones up to a weight of 300 kilograms and a diameter of 1,100 millimetres.
After forging on presses by conventional or isothermal methods or on counterblow hammers, the products are heat-treated in several steps and subjected to extensive, non-destructive testing. We supply the disks according to the customer's wishes as forged parts, with an ultrasonic contour, almost final shape or turned to the final contour. In cooperation with our works in Nuremberg we can also supply ready-to-install 'blisks', in other words disks with integrated blades. Aircraft engine disks from Leistritz are 'Class 1' aviation parts and thus satisfy the highest requirements of our customers.
We manufacture an increasing number of parts for aircraft engine casing as well as other structural parts for aviation. The trend for lightweight constructions is leading to a re-design of traditional cast parts as components from a forged material. Our portfolio ranges from forged annulus fillers from an aluminium alloy, brackets and bearing supports of special steels or to top lugs (aircraft engine holders) of a nickel-based alloy. The feedstock for our production is usually an oversize forged part.
Titanium aluminide turbine blades
The latest generation of modern aircraft engines rely on blades of gamma-titanium aluminide materials to save weight in the low-pressure turbine. These new material classes have a thermal stability comparable to that of nickel-based alloys, but only half the density.
Depending on the required properties profile of the components, they are manufactured by either precision casting and/or forging, each with a subsequent processing to the finished size.
