One of the challenges in the development of new aircraft is to have increasingly faster vertical takeoff and landing aerial systems.<\/p>\n

HSVTOL aircraft projects since the 1960s<\/big><\/p>\n

Projects to build this type of aircraft began as early as the 1960s, with several projects by Bell Helicopters<\/a> (the manufacturer of the famous UH-1 Huey helicopter) such as the X-14, the X-22, the -3, the XV-15, the Bell 533 and the Eagle Eye TR911X<\/strong>, aircraft that did not go beyond the experimental phase and at most only prototypes were built.<\/p>\n

Bell Textron's new HSVTOL concept<\/big><\/p>\n

On August 2, 2021, Bell Textron announced a new HSVTOL<\/a> concept, i.e. high-speed vertical take-off and landing<\/strong>, using a new propulsion system made in collaboration with Pratt & Whitney<\/a>. In that first announcement, Bell Textron showed this first image of what this new generation of aircraft could be:<\/strong><\/p>\n

What we see, apparently, are two manned aircraft (left and center) and one unmanned (right).<\/strong> Its appearance corresponds to that of a convertiplane, a technology that Bell successfully developed together with Boeing giving rise to the V-22 Osprey<\/strong>, whose first flight took place in 1989 and which is today operational in the US and Japanese Armed Forces. However, there is an important difference between these HSVTOL aircraft and current convertiplanes<\/strong>. In March 2023, Bell Textron showed that difference in this video:<\/p>\n
