Constructed by the Douglas Plane Firm, the X-3 Stiletto had an unorthodox, virtually futuristic design. Maj. Charles E. Yeager, the primary pilot to interrupt the sound barrier, was within the inspection crew for the plane and influenced its design. The X-3 had brief, stubbed wings and a protracted nostril, making the general construction mimic a stiletto heel. A pressurized cockpit was embedded inside its slender fuselage, providing a restricted view to the pilot who sat in a reclined, downward ejecting seat, which doubled as an electronically managed raise.
The X-3 was additionally the primary plane to make use of titanium in its development in a bid to discover the viability of the ingredient in airframes. Additionally nestled within the cramped fuselage had been the 2 Westinghouse J34 turbojets powering the X-3 towards its bold targets. These J34s had been really underpowered substitutes when the initially deliberate higher-thrust J36s failed to satisfy this system’s calls for and timelines.
