The term “BLISK” is an acronym composed of the words “blade” and “disk” (from Bladed Disk), which is a single part, instead of an assembly of a disk and individual, removable blades. Even though it’s fairly old technology and was introduced in 1980’s, the use of it is predominantly limited to the high precision aviation industry, to have enhanced reliability and safety.
For us at TurboTech, it’s a daily affair to use the BLISK in our Energy Conservation Turbine (ECT TM), machined as one piece, with blades and disks integral.

  • It is machined from precipitated, hardened, stainless steel using 4-axis CNC milling
  • It has an added advantage of high aerodynamic efficiency, as it diminishes leakage flows
  • It is high strength design, No Joints, eliminates the fretting fatigue failure possibility to nil.
  • Further, it eliminates the possibility of blade release, as the material selected has an elongation, sufficiently large to have blade rub, which will seize the turbine well before it approaches the burst speed. This is the same technique used in aviation industry to prevent rotor burst
  • The construction results in an exceedingly robust rotor, capable of withstanding the stresses at over-speed of 150%.

Even though with many advantages, it is laborious, expensive and an exhaustive quality control is required to ensure reliable performance, especially when small in size.

We at TurboTech know how to overcome these limitations, confirming our turbines with high aerodynamic efficiency, reliability and safety, guaranteeing best life cycle value to our customers.

TurboTech Recuperated Gas Turbine

TurboTech’s ‘tech Series’ is here with curated articles on products and innovation that demonstrate our in-house technology.

One of the predominant accolades that we hear often is, “TurboTech is like a university of Turbomachinery in itself”, this humbles us and motivates us to strive for better innovation-led technology in the field.
