Innovations in the Hawker Hurricane's Landing Gear System

The Hawker Hurricane, a renowned British single-seat fighter aircraft of World War II, incorporated a distinctive inward-retracting landing gear system. This system was ingeniously integrated into the wing structure, with the main gear pivoting on hinged telescopic legs produced by Vickers. The design allowed the wheels to align with the aircraft's thrust line when extended, ensuring stability during takeoff and landing. The gear retracted into the wings, clearing the forward spar, and was operated by a hydraulic system with both power and manual options, providing redundancy. The wide track of the landing gear afforded the Hurricane excellent ground handling and maneuverability.

Advancements in Propulsion and Pilot Visibility for the Hurricane

The Hurricane initially flew with a Watts two-bladed fixed-pitch propeller, which was later replaced by a de Havilland variable-pitch propeller to improve takeoff performance. This was a crucial upgrade that shortened takeoff distances and enhanced overall agility. The aircraft was further refined with the introduction of a Rotol constant-speed propeller, which was instrumental in optimizing performance for the Battle of Britain. The Hurricane's design also emphasized pilot visibility, with a high-mounted cockpit providing an expansive field of view. The cockpit was accessible via a retractable stirrup and featured non-slip surfaces on the wing roots for added safety during ingress and egress.
