There are 6 different research concepts to be explored in SABRE, which are targeted at morphing the primary rotor design parameters:

Active Camber
Fish Bone Active Camber (FishBAC) – Bristol
Translation Induced Camber (TRIC) – TU Delft

Active Twist
Inertially Driven Twist – Swansea
Shape Memory Alloy Driven Twist – CIRA

Chord Extension – DLR

Active Tendons (Variable blade dynamic properties) – Bristol

Passive Energy Balancing will be explored as a means of reducing the actuation requirements of the various concepts.
