the mid-1940s but which never saw production or active duty. It competed with similar designs, the <a href="/wiki/North_American_XB-45" class="mw-redirect" title="North American XB-45">North American XB-45</a> and <a href="/wiki/Martin_XB-48" title="Martin XB-48">Martin XB-48</a>, all of which saw little use after the successful development of the <a href="/wiki/Boeing_XB-47" class="mw-redirect" title="Boeing XB-47">Boeing XB-47</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Development">Development</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Convair_XB-46&action=edit&section=1" title="Edit section: Development"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In 1944, the <a href="/wiki/United_States_Department_of_War" title="United States Department of War">War Department</a> was aware of aviation advances in Germany and issued a requirement for a range of designs for medium bombers weighing from 80,000 pounds (36,000 kg) to more than 200,000 pounds (91,000 kg). Other designs resulting from this competition, sometimes named the <i>class of '45</i>, included the <a href="/wiki/North_American_XB-45" class="mw-redirect" title="North American XB-45">North American XB-45</a> and the <a href="/wiki/Martin_XB-48" title="Martin XB-48">Martin XB-48</a>. Procurement began with a letter contract (cost-plus-fixed-fee) on 17 January 1945 with <a href="/wiki/Mockup" title="Mockup">mockup</a> inspection and approval in early February. Orders for three prototypes followed on 27 February 1945 with certain changes recommended by the board. Serials <i>45-59582</i> to <i>59584</i> were assigned. Budgetary concerns also led to the contract being changed to a <a href="/w/index.php?title=Fixed-price&action=edit&redlink=1" class="new" title="Fixed-price (page does not exist)">fixed-price</a> type. </p><p>In the fall of 1945, Convair found it was competing with itself when the USAAF became interested in an unorthodox <a href="/wiki/Forward-swept_wing" title="Forward-swept wing">forward-swept wing</a> jet attack design, the <a href="/wiki/Convair_XA-44" class="mw-redirect" title="Convair XA-44">XA-44</a>-CO that the company had also been working on. With the end of <a href="/wiki/World_War_II" title="World War II">World War II</a> severely curtailing budgets, the company considered canceling the XB-46 in favor of the other project as there was insufficient funding for both. Company officials argued that it made more sense to allow them to complete the XB-46 prototype as a stripped-down <a href="/wiki/Testbed" title="Testbed">testbed</a> omitting armament and other equipment and for the AAF to allow them to proceed with two XA-44 airframes in lieu of the other two XB-46s on contract. In June 1946, the AAF agreed to the substitution but that project was ultimately cancelled in December 1946 before the prototypes were completed. The B-46 would be completed with only the equipment necessary to prove its airworthiness and handling characteristics. </p><p>The XB-46 had a long streamlined oval torpedo-shaped <a href="/wiki/Fuselage" title="Fuselage">fuselage</a>, long narrow straight shoulder-mounted wings with four Chevrolet-built <a href="/wiki/Allison_J35" title="Allison J35">J35-C3</a> axial-flow eleven stage <a href="/wiki/Turbojets" class="mw-redirect" title="Turbojets">turbojets</a> of 3,820 pounds-force (17.0 kN) static thrust paired in an integral <a href="/wiki/Nacelle" title="Nacelle">nacelle</a> under each wing. The fuselage turned out to be a problem, as it distorted under flight loads.

The unusual <a href="/wiki/Aircraft_flight_control_system" title="Aircraft flight control system">flight control system</a> utilized a system of <a href="/wiki/Pneumatics" title="Pneumatics">pneumatic</a> piping to transmit the pilot's control inputs and actuate various systems, rather than the more typical <a href="/wiki/Hydraulics" title="Hydraulics">hydraulic</a>, manual or <a href="/wiki/Electrical_wiring" title="Electrical wiring">electrical</a> control lines and systems of most aircraft of the era. </p><p>Production versions were to be equipped with a pair of <a href="/wiki/.50_BMG" title=".50 BMG">.50</a> caliber <a href="/wiki/M2_Browning" title="M2 Browning">Browning M2</a> <a href="/wiki/Machine_gun" title="Machine gun">machine guns</a> in a tail turret designed by <a href="/wiki/Emerson_Electric_Company" class="mw-redirect" title="Emerson Electric Company">Emerson Electric Company</a> and provision was made for an <a href="/w/index.php?title=APG-27&action=edit&redlink=1" class="new" title="APG-27 (page does not exist)">APG-27</a> remote control <a href="/wiki/Optics" title="Optics">optics</a> and sighting system, but no weaponry was fitted into the prototype. Likewise, production aircraft were intended to be built with the <a href="/wiki/General_Electric_J47" title="General Electric J47">General Electric J47</a> engines with 5,200 lbf (23 kN) static thrust rather than the J35s used on the prototype. </p> <div class="mw-heading mw-heading2"><h2 id="Testing">Testing</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Convair_XB-46&action=edit&section=2" title="Edit section: Testing"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The XB-46's first flight occurred 2 April 1947 after a month of taxi testing, and lasted ninety minutes as the bomber departed the Convair plant in <a href="/wiki/San_Diego" title="San Diego">San Diego</a>, <a href="/wiki/California" title="California">California</a> for <a href="/wiki/Muroc_Army_Airfield" class="mw-redirect" title="Muroc Army Airfield">Muroc Army Airfield</a> in the <a href="/wiki/High_Desert_(California)" title="High Desert (California)">high desert</a>. The pilot praised its handling qualities. Basic flight testing took place for five months, and by September 1947 it was concluded after 127 hours aloft on 64 flights by both the Convair company and AAF <a href="/wiki/Test_pilots" class="mw-redirect" title="Test pilots">test pilots</a>. Stability and control were excellent but there were engineering problems with engine de-icing, the cabin air system, and vertical oscillations caused by harmonic resonance between the wing and spoilers. There was also concern regarding the ability of the three man crew to exit the aircraft in case of an emergency, since the exit plan relied on the pneumatic system to hold the main door open against the airstream. The aircraft was accepted on 7 November and delivered on 12 November 1947. </p> <div class="mw-heading mw-heading2"><h2 id="Cancellation">Cancellation</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Convair_XB-46&action=edit&section=3" title="Edit section: Cancellation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>The B-46 program was cancelled in August 1947, even before flight testing had been completed, because it was already obsolete. The <a href="/wiki/North_American_B-45_Tornado" title="North American B-45 Tornado">North American B-45 Tornado</a> already had production orders, and even it would be eclipsed by the <a href="/wiki/Boeing_B-47_Stratojet" title="Boeing B-47 Stratojet">Boeing B-47 Stratojet</a>'s superior performance. Furthermore, the bulky <a href="/wiki/Radar" title="Radar">radar</a> <a href="/wiki/Fire-control_system" title="Fire-control system">fire-control system</a> which was not installed in the XB-46 prototype would have undoubtedly forced an expensive redesign of the slender fuselage.

After 44 additional flight hours, the XB-46 was taken out of service, since the cost of support and maintenance, coupled with a lack of spare parts, had become prohibitive. After sitting idle for a year, it was flown to <a href="/wiki/Eglin_Air_Force_Base" title="Eglin Air Force Base">Eglin Air Force Base</a>, <a href="/wiki/Florida" title="Florida">Florida</a>, in July 1950, where its <a href="/wiki/Pneumatic" class="mw-redirect" title="Pneumatic">pneumatic</a> system was tested under the coldest conditions in the large <a href="/wiki/McKinley_Climatic_Laboratory" title="McKinley Climatic Laboratory">climatic facility</a> there. Most jet aircraft of this period used hydraulic or electrical systems, so the pneumatic control system of this aircraft offered a unique opportunity for investigation. When this testing program was concluded in November 1950, the Air Force no longer had need for the XB-46, a fact acknowledged in the press as early as August,<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> and on 13 January 1951 the nose section was sent to the <a href="/wiki/National_Museum_of_the_United_States_Air_Force" title="National Museum of the United States Air Force">U.S. Air Force Museum</a> at <a href="/wiki/Wright-Patterson_Air_Force_Base" title="Wright-Patterson Air Force Base">Wright-Patterson Air Force Base</a>, <a href="/wiki/Ohio" title="Ohio">Ohio</a>, although it appears that the airframe section has not survived in the collection.
