Cornelius Mallard
The Cornelius Mallard was a single-engined light aircraft of very unusual configuration, tailess and with a swept forward wing of variable incidence. It flew between 1943-4.
==Design and development==
The Mallard was the third aircraft type produced by Cornelius Aircraft.〔''Flight'' January 1990〕 The first two, the FreWing and the LW-1 were conventional in layout but unusual in using independently variable incidence wings for pitch and roll control. The wings of the Mallard could also be adjusted in the air,〔〔''Flight'' December 1989〕 but they were of low aspect ratio with marked forward sweep. The trailing edge carried conventional ailerons near the tips and elevators close to the fuselage. The Mallard was also a tailess aircraft, in the sense of lacking a horizontal tailplane. The rest of the aircraft was conventional, with single fin and rudder and a side by side cockpit for two behind a flat four engine. The undercarriage was fixed and of the tailwheel type. Like other Cornelius designs, the sole Mallard was built by the Spartan Aircraft Company.〔
The Mallard first flew on 18 August 1943, flown by Arthur Reitherman,〔 though some sources〔''Flight'' September 2002〕 suggest that most of the subsequent 18 flights were in the hands of the Romanian aerobatic pilot Alexander Papana. The first public flight was on 7 September 1943.〔 It was reported to have been 700 lb (320 kg) overweight〔 and there were plans to install a more powerful engine. The designer claimed that the Mallard was stall and spin proof, though the later loss of the much larger but similarly configured Cornelius XFG-1 in an irrecoverable spin has cast doubt on this.〔''Flight'' November 1989〕
