Bennett</a> while he was chief technical officer at the <a href="/wiki/Cierva_Autogiro_Company" title="Cierva Autogiro Company">Cierva Autogiro Company</a> in 1936–1939. The Gyrodyne, constituting a third distinct type of rotorcraft and designated C.41 by the Cierva Autogiro Company, was in 1938 successfully tendered to the <a href="/wiki/Royal_Navy" title="Royal Navy">Royal Navy</a> in response to <a href="/wiki/List_of_Air_Ministry_specifications" title="List of Air Ministry specifications">Specification S.22/38</a> for a naval helicopter. Though preliminary work started on the project, it was abandoned with the outbreak of the <a href="/wiki/World_War_II" title="World War II">Second World War</a>, and G & J Weir, Ltd., the financiers of the Cierva Autogiro Company, declined to undertake further development in addition to their successful experiments with the <a href="/w/index.php?title=Weir_W.5&action=edit&redlink=1" class="new" title="Weir W.5 (page does not exist)">W.5</a> and <a href="/w/index.php?title=Cierva_W.6&action=edit&redlink=1" class="new" title="Cierva W.6 (page does not exist)">W.6</a> lateral twin-rotor <a href="/wiki/Helicopter" title="Helicopter">helicopters</a>.

The Gyrodyne possessed the hovering capability of a helicopter, while its propeller provided the necessary thrust for forward flight to enable its rotor, driven at low torque in cruise flight, to operate at low collective pitch with the tip-path plane parallel to the flight path to minimise vibration at high airspeed. Collective pitch was an automatic function of throttle setting and power loading of the propeller, which to maintain rpm diverted torque away from the rotor as airspeed increased.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>A government contract to <a href="/wiki/List_of_Air_Ministry_Specifications" class="mw-redirect" title="List of Air Ministry Specifications">Specification E.4/46</a> was awarded for two prototypes with the first Fairey Gyrodyne exhibited as an almost complete airframe at <a href="/wiki/White_Waltham" title="White Waltham">White Waltham</a> on 7 December 1946. </p> <div class="mw-heading mw-heading2"><h2 id="Testing_and_evaluation">Testing and evaluation</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fairey_FB-1_Gyrodyne&action=edit&section=2" title="Edit section: Testing and evaluation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>On 4 December 1947, the first of the two prototypes took off from <a href="/wiki/White_Waltham_Airfield" title="White Waltham Airfield">White Waltham airfield</a>, and continued to build up flying time until March 1948 when it was dismantled for a thorough examination. The second prototype, basically similar to the first but with more comfortable interior furnishings befitting its role as a passenger demonstrator, was flying by the time of the next <a href="/wiki/Society_of_British_Aerospace_Companies" title="Society of British Aerospace Companies">SBAC</a> <a href="/wiki/Farnborough_Airshow" class="mw-redirect" title="Farnborough Airshow">Farnborough Airshow</a>, in September 1948. The first prototype was reassembled and, following further test flying, took part in an attempt to set a new world helicopter speed record in a straight line.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p><p>On 28 June 1948, flown by test pilot Basil Arkell, the Gyrodyne made two flights in each direction over a low-altitude 2-mile-long (3.2 km) course at White Waltham, achieving 124 mph (200 km/h), enough to secure the record.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> A maximum airspeed of 133 mph (214 km/h) was achieved during the flight, keeping seven inches of boost in reserve in the event a rapid climb became necessary as the flight was conducted at an altitude of less than 100 ft (30 m) above the ground. An attempt was to be made in April 1949 to set a 62 mi (100 km) closed-circuit record, but two days before the date selected a poorly machined flapping link in the rotor hub failed during flight and resulted in the crash of the aircraft at Ufton, near <a href="/wiki/Reading,_Berkshire" title="Reading, Berkshire">Reading</a>, killing the pilot, Foster H.

Though the Gyrodyne's projected performance was significantly better than that of the Dragonfly, and was expected to be in service earlier than the Sycamore, the crash of the first prototype delayed the development programme, and the Army, having no other choice, acquired three S.51 Dragonflies, followed by Sycamores at a later date. </p> <div class="mw-heading mw-heading2"><h2 id="Second_prototype">Second prototype</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Fairey_FB-1_Gyrodyne&action=edit&section=3" title="Edit section: Second prototype"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r1236090951">.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}@media print{body.ns-0 .mw-parser-output .hatnote{display:none!important}}</style><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Fairey_Jet_Gyrodyne" title="Fairey Jet Gyrodyne">Fairey Jet Gyrodyne</a></div> <p>The second Gyrodyne was grounded during the accident investigation which determined flapping hinge retaining nut failure due to poor machining as the cause. The extensively modified second prototype, renamed <a href="/wiki/Jet_Gyrodyne" class="mw-redirect" title="Jet Gyrodyne">Jet Gyrodyne</a>, flew in January 1954. Though retaining the name "Gyrodyne", the Jet Gyrodyne was a <a href="/wiki/Gyrodyne#History" title="Gyrodyne">compound gyroplane</a>, and did not operate on the same principle as the original aircraft. It had a two-blade rotor manually controlled with cyclic and collective pitch mechanisms that acted directly on each rotor blade and was driven by tip jets fed with air from two compressors driven by the Alvis Leonides radial engine. Pusher propellers, one mounted at the tip of each stub wing, provided yaw control through differential collective pitch and thrust for forward flight. The Jet Gyrodyne was constructed to provide rotor drive and operational data for the <a href="/wiki/Fairey_Rotodyne" title="Fairey Rotodyne">Fairey Rotodyne</a> compound gyroplane. </p><p>The Jet
