Abstract
A turbine blade for use in a gas turbine engine, where the turbine blade is made from a spar and shell construction in which a thin walled shell is held in place between the blade tip and the platform by only a mechanical fastener without using any bonding, welding or brazing. The spar is connected to an attachment by a tie bolt, and a separate platform is secured, over the attachment t in which the shell is held against. This provides for a thermally free platform and shell connection. With this arrangement, the shell is held under compression within the 2% yield stress range such that the turbine blade shell can have an infinite life. Also, the turbine blade is much lighter than prior art blades. As a result, the spar and shell blade produces less stress on the rotor disk during engine operation.
