E-3120 Low speed shaft (LSS)

Endurance E-3120 Low Speed Shaft Failure

The LSS connects the rotor to the gearbox and transmits all the energy generated by the turbine blades.

Prior to going bankrupt EWP admitted the LSS design was marginal, this has been borne out by many LSS failures resulting in repair bills exceeding £60,000.

DC21 can offer a new LSS that has been designed and manufactured in the UK.

The design has several key features:

  1. Reduces the maximum stress in the shaft by 50%.
  2. Eliminates the keyway, a common failure point
  3. Eliminates hub slip, a common cause of LSS failure
  4. Assembled using branded bearings with increased load capacity
