http://visi.net/~djohnson/lippisch/3blp13a.jpg [not image] Dr. Alexander Lippisch designed this ramjet powered interceptor in late 1944, much of the research coming from his work on the DM-1 test glider (see below). The wings were sharply swept back at 60 degrees, and there was a single large fin and rudder in which the cockpit was located. The ramjet was fed by a circular intake that protruded from the nose, and exhausted beneath the vertical fin at the rear. Research in the DVL high-speed windtunnel indicated that the P.13a had outstanding stability up to the maximum tested speed of Mach 2.6, and no unfavorable characteristics in the subsonic range. A liquid fueled rocket motor was planned for takeoff and to get the aircraft to ramjet operating speed.Since fuel was in short supply by this stage in the war, powdered coal was to be used in the ramjet.

Span: 6.0 m (19' 8.4") Length: 6.7 m (22') Max. Speed: 1650 km/h (1025 mph)

The Lippisch P.13b was a follow-on design from the P.13a, and was also a ramjet fighter. Designed in December 1944, it featured Lippisch's favorite wing plan, a delta design (sweepback was 60 degrees) with downturned wingtips. A double fin and rudder was chosen, and the cockpit was moved to a forward position, ahead of the delta wing's apex. On each side of the cockpit on the wing's leading edge were the air intakes which fed the ramjet. Because of the fuel shortage in Germany at this stage in the war, an ingenious plan to use coal (or paraffin coated lignite dust) for fuel was to be tried. A centrally installed round or hexagonal heat-resistant ceramic combustion chamber was fitted in the interior of the wing, and was fillable from above. The main landing gear was a retractable landing skid, and the rear rested on the reinforced downturned wingtips. No armament was planned at this stage, and no tests were ever carried out with this design or with the unique power source.

Вот бы картинки перехватчика Р Бартини найти!
М=2 в 1943 году!

После войны Lippisch уехал в США, и там его работы послужили основой для создания Ф-102 и Ф-106.
А еще он сделал маленькие и дешевые экранопланы с ДВС.
