The SmartBird can start, fly and land autonomously with no additional drive mechanism

UK based Festo, a leading supplier of automation technology globally, has succeeded in unravelling the mystery of how birds fly. SmartBird is an ultra light powerful flight model with excellent aerodynamic qualities and extreme agility. With SmartBird, Festo has succeeded in deciphering the flight of birds.

The bionic technology-bearer, which is inspired by the herring gull, can start, fly and land autonomously with no additional drive mechanism. Its wings not only beat up and down, but also twist at specific angles. This is made possible by an active articulated torsional drive unit, which in combination with a complex control system attains an unprecedented level of efficiency in flight operation.

An unusual feature of SmartBird is the active torsion of its wings and the fact that it dispenses with the use of additional lift devices. The aim of the SmartBird project was to achieve an overall structure that is efficient in terms of resource and energy consumption, with minimal overall weight, in conjunction with functional integration of propulsion and lift in the wings and a flight control unit in the torso and tail regions. Further requirements were excellent aerodynamics, high power density for propulsion, and maximum agility for the flying craft. The outcome is an intelligent biomechatronic overall system.

The onboard electronics ensure precise wing control. In addition, the torsion control parameters can be adjusted and thus optimised in real time during flight. The wing flapping and twisting sequence is controlled within a few milliseconds and results in optimum airflow around the wings. The SmartBird flight model has no rotating parts on its exterior and therefore cannot cause injury.
