Concorde Delta Edged Fairey Modification Ogival Sharp Wg774 Wing
EDITORS COMMENTS
This photograph showcases the first Fairey Delta 2, WG774, undergoing significant modifications that transformed it into the BAC 221. The Fairey Delta 2 was a groundbreaking British supersonic research aircraft, first flown in 1954. However, its original round wing design was not ideal for achieving the high-speed, low-drag characteristics required for future supersonic transport aircraft, such as Concorde. To address this challenge, the Wing Commander W.E.W. Williams team at the Royal Aircraft Establishment (RAE) initiated an ambitious modification project. The photograph captures the Delta 2, WG774, after the installation of a sharp-edged ogival wing, a critical component of the Concorde-style delta wing. This modification was a crucial step in validating the aerodynamic performance of the new wing design. The BAC 221, as the modified Delta 2 came to be known, underwent extensive testing at the RAE and the Aerodynamics Research and Development Establishment (ARDE). The aircraft's innovative wing design provided invaluable data for the development of the Concorde, which first flew in 1969. The BAC 221's contributions to aviation history are evident in the sharp edges and sleek lines of this iconic photograph. This photograph is a testament to the pioneering spirit of aviation engineers and their unwavering commitment to pushing the boundaries of what is possible in aircraft design. The Fairey Delta 2's transformation into the BAC 221 represents a significant milestone in the history of supersonic aviation, paving the way for the development of the iconic Concorde.
