non-retractable undercarriage

All had fixed, non-retractable undercarriage with (except for the trainers) wheel spats.

To begin flight testing, a temporary non-retractable undercarriage with long braced V-legs was attached to the fuselage, and fixed tail wheels attached to the lower pair of fins.

At the time that the Hurricane was developed RAF Fighter Command consisted of just 13 squadrons, each equipped with either the Hawker Fury, Hawker Demon, or the Bristol Bulldog, all biplanes with fixed-pitch wooden propellers and non-retractable undercarriages.
