Low-Boom Design for Supersonic Transport with Canard and Forward-Swept Wings Using Equivalent Area Design Method
Published 2023-08-01“…The design results indicated that the forward-swept wing configuration with a canard could divide the single peak of the leading boom into two peaks. Thus, the sonic boom strength of the canard configuration was 2.5 PLdB lower than that of the configuration without the canard wing.…”

Whatever Happened to Delia Derbyshire? Delia Derbyshire, Visual Art, and the Myth of her Post-BBC Activity
Published 2019-05-01“…For many years, the standard account of Derbyshire’s life has been that, following her departure from the BBC in 1973, she withdrew from creative activity until the final few years of her life when she began to collaborate with Peter Kember (Sonic Boom). These accounts have sometimes veered into sensationalist cliché—a 2008 article in The Times characterised Derbyshire as a tragic and self-destructive artist who abandoned music for “a series of unsuitable jobs” and became a “hopeless alcoholic”.1 Recent discoveries and donations to the Delia Derbyshire Archive, however, have pointed to a more complex understanding of Derbyshire’s activity after she left the BBC. …”
