Design and Development
Within nine days of the 15 July 1944 issuance of the design specifications for the Emergency Fighter, the Messerschmitt design bureau under Woldemar Voigt had formed a preliminary paper design for the P.1101. The aircraft which was developed initially had a short and wide fuselage, tricycle landing gear, and mid-mounted wings with an inner sweep of 40 degrees near the fuselage, and a shallower 26 degree angle outboard. The single He S 011 jet engine was to be mounted internally within the fuselage, being aspirated by two rounded intakes located on either side of the cockpit. The tail was of a V configuration, and mounted on a tapered boom which extended over and past the jet exhaust, while the cockpit was forward mounted, with the canopy integrated into the fuselage and forming part of the rounded nose of the aircraft.
By late August 1944, the design still in paper form had evolved into a sleeker incarnation, with the previously stout fuselage lengthened and narrowed with a conical nose section added in front of the cockpit. The double angled wing was also abandoned, with the outer wing of the Me 262 instead being adapted for the design. The design was further developed, and after the wind tunnel testing of a number of wing and fuselage profiles, the design was further modified and finalized, with the decision made to undertake the construction of a full-scale test aircraft. This finalized design and associated test data were submitted to the Construction Bureau on 10 November 1944 and the selection of production materials was begun on 4 December 1944.
On 28 February 1945, the RLM settled on a competing design, the Focke-Wulf Ta 183, as the winner of the Emergency Fighter program. This decision was based in part on the considerable design difficulties being encountered by the Messerschmitt P.1101 design team. For example, the cannon installation was proving too crowded, the mainwheel retraction and door mechanisms were too complex, the fuselage needed a great number of "strong points" to deal with loads, and the anticipated performance had fallen below the RLM specifications due to increased weight.

Famous quotes containing the words design and/or development:
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
—Sidney Buchman (1902–1975)
“They [women] can use their abilities to support each other, even as they develop more effective and appropriate ways of dealing with power.... Women do not need to diminish other women ... [they] need the power to advance their own development, but they do not “need” the power to limit the development of others.”
—Jean Baker Miller (20th century)
