The development of programs for machining of each new blisk
requires about two days, taking into account the time spent on the construction of 3D models of the parts and the blanks.
Dave Ramahi, President of Optomec, said, "This award continues to extend Optomec's lead in providing a commercial system for blisk
is an engine component composed of a rotor and a blade, which has been machined from a solid piece of material.
In addition, the LENS process was able to demonstrate economic viability to repair blisks
that would otherwise cost hundreds of thousands of dollars to replace.
It is a simultaneous 5-axis contouring horizontal machining center that answers all six design criteria, and then some, especially in the machining of a turbine blisk
from a solid disc or forging to a perfectly finished bladed component.
GE and R-R are jointly developing an integrated high-pressure/low-pressure counterrotating turbine design, while R-R is responsible for the combustor/diffuser system, gearboxes, and an advanced high-pressure-ratio, long-chord, hollow, titanium blisk
Among those who agree that Lockwood's prospects for continued success are bright is David Blisk

The high pressure compressor's first three stages feature a blisk

The Passport engine for the Global 7000 and Global 8000 business jets will produce up to 16,500 pounds of thrust and incorporate advanced technologies, including a composite fan case and a front fan blisk
that is designed to reduce weight and lower cabin noise and vibration.
