Williams has confirmed the departure of its head of aerodynamics Dirk de Beer just weeks after Ed Wood left his role as chief designer for personal reasons.
His departure marks the end of a relationship that has lasted for just over one season, with De Beer having previously held the same role at F1 rivals Ferrari.
It has been a difficult season so far for Williams, with the British outfit bottom of the constructors’ championship table on four points.
“The team would like to thank Dirk for his hard work over the past year and wish him the best for the future.”
Williams confirmed that Chief Engineer Doug McKiernan, who joined the team in Feburary having worked at McLaren for 16 years from 1999, will “assume full responsibility over the aerodynamic and design direction of the car”.
They added: “Dave Wheater is stepping up to take on the role as Head of Aerodynamics.”
