Blohm & Voss Bv P.188.02 (Unicraft, Resin)

TYPE: Heavy jet-bomber. Project

ACCOMMODATION: Crew of two

POWER PLANT: Four Junkers Jumo 004C-1 turbojet engines, rated at 1,020 kp thrust each

PERFORMANCE: 509 mph

COMMENT: This Blohm & Voss jet bomber project was designed to carry a great bomb load and enough fuel for long distance operations. There were four different designs, P.188.01 to P.188.04. Common to all was a rather wide fuselage center section – except for the Bv P.188.04 whose fuselage was slender – designed as an armored steel shell and located in the center of gravity. This caused a special arrangement of the landing gear in all projects with twin main wheels in tandem with an auxiliary outrigger landing gear outboard from the wings. Very unusual was the W-type layout of the wings. These had a constant 3 degree dihedral with the inner section swept back to 20 degree and then a 20 degree swept forward outer section. This was calculated to give good performance at both low and high speeds. The only drawback was excessive air pressure on the wing tips, which was to be corrected by a variable incidence system which could be adjusted through 12 degrees. An advantage of this arrangement was the fact that the fuselage was constant horizontal during take-off and landing. The crew sat in a pressured, extensively glazed cockpit. Four Junkers Jumo 004 C-1 turbojets were mounted in four single nacelles, two beneath each wing, again except for the Bv P.188.04 where two engines were combined in one nacelle on each side. Both designs of the Bv P.188.01 and Bv P.188.03 had a single fin and rudder design and an airbrake at the tail, while the Bv P.188.02 and Bv P.188.04 were of a twin fin and rudder design, with a dihedral tail-plane and the extreme tail had a remote-controlled FDL 131 Z twin 13mm machine guns firing to the rear. All these futuristic designs remained on the drawing boards (Ref.: 17).

Blohm & Voss Bv P. 163.02 (RS Models, Resin)

TYPE: Heavy fighter bomber. Project.

ACCOMMODATION: Crew of five

POWER PLANT: One BMW 803, a combination of two BMW 801 radial engines, coupled back to back, rated at 3,847 hp, driving three-bladed contra-rotating propellers

PERFORMANCE: 354 mph

COMMENT: This very unorthodox Blohm & Voss design of a single-engine heavy attack bomber dates back to 1942. Basic concept was the construction of a heavy aircraft around the most powerful engines available in Germany at that time. Two versions were proposed to the RLM differing primarily in the power units.  While the Bv P. 163.01 was powered by a Daimler-Benz DB 613C liquid-cooled engine, a side-by-side arrangement of two DB 603G engines, rated together at 3,800 hp, the Bv P. 163.02 was to be powered by a BMW 803 engine, a back-to-back combination of two BMW 801 radial engines, rated at 3,850 hp. All engines drove three-blades, contra-rotating propellers. Very unusual were the location of the cockpits for crew-members. The pilot and navigator/radio operator sat in a nacelle located at the extreme end of port wing, with a rear gunner in a turret with two twin mounted MG 151 15mm machine guns to the rear. Another nacelle was located on the starboard wingtip and was manned by two gunners, one firing a machine gun forward from the front and a second from turret on the top of the nacelle, the other gunner sat in a turret at the rear, also with two machine guns. The bomb-bay was located mid-fuselage, over-load bombs could be carried under wing-root mounted racks. In order to test this unusual arrangement an asymmetrical Blohm & Voss Bv 141 was equipped with a second cockpit installed on the wingtip, the controls coupled with those in the main cockpit. The results showed that this arrangement warranted no advantage and the projects were cancelled (Ref.: 17).

Gotha P. 60C (Planet, Resin)

TYPE: Night fighter. Project

ACCOMMODATION: Pilot and radar operator

POWER PLANT: Two Heinkel-Hirth HeS-11 turbojet engines, rated at 1,500kp

PERFORMANCE: 596 mph, estimated

COMMENT:  In August 1944 the Gotha Aircraft Company was given the order of series production of the Horten Ho IX flying wing fighter, designated Go 229A. But additionally, in January 1945 the Gotha engineers proposed a series of altrenate all-wing design to the RLM which used many of the construction techniques as the Horten aircraft but had the advantage of being able to be modified with new equipment and engines without changing the flying characteristics. Three designs were proposed, and designation Gotha Go P.60A, Go P.60B, and Go P.60C was given. All were of delta-shaped., flying wing design, and powered by two turbojet engines at the rear end, one engine above the wing, the other slung under the fuselage. A two men crew sat in a pressurized and armored cockpit, located in the extreme nose. For its duty as night fighter the aircraft was equipped with the most modern radar available at that time. The Gotha Go P.60A was powered by two BMW 003A-1 turbojet engines, rated at 800 kp each, the crew laid in prone position. The Gotha Go P.60B was a further development of the P.60 series which simplified construction by utilizing an easier to build airframe and a conventional rudder. The two-seat cockpit was located behind the radar equipment in a fuselage section. The two engines were upgraded to Heinkel-Hirth HeS 011 turbojets. The RLM approved the construction of the project in 1945, but later construction of the prototype was halted in favor of the Go P.60C. This was the final design of the Gotha Go P.60 series, the P.60C night fighter. The fuselage was lengthened to accommodate the installation of the newest radar set with its “Morgenstern” (Morningstar) or the the FuG 240 “Berlin” antenna. The end of the war prevented further development (Ref.: 16).

Heinkel “Lerche II” (“Lark II”) (Fruitbat, Resin)

TYPE: Target defense interceptor. Project.

ACCOMMODATION: Pilot only, in prone position

POWER PLANT: Two Daimler-Benz DB 603E inline engines, rated at 2.400 hp each, driving contra-rotating propellers

PERFORMANCE: 497 mph

COMMENT: This Heinkel Vertical Take Off and Landing (VTOL) fighter/interceptor project was based on an earlier design, the Heinkel “Wespe” (Wasp). Work on the design started at the Heinkel Company in Vienna on February 25, 1945 and was completed on March 8, 1945. The “Lerche” (Lark) employed a ducted wing planform with contra-rotating propellers, powered by two Daimler-Benz DB 605E engines. This arrangement increased the effectiveness of the airscrews dramatically. During flight the pilot lied in a prone position in the extreme nose, while standing upright during take-off and landing. Projected armament was two MK 108 30mm cannon. The end of the war brought any realization to a termination. After the war this idea of a tail sitter was developed further by the US Navy, e. g. Convair XFY-1 Pogo and Lockheed XFV-1 Salmon (Ref.: 16).

Messerschmitt Me P.1101 NJ (Nachtjäger, Night fighter, Dragon)

TYPE: Night fighter. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Heinkel-Hirth HeS011 turbojet engine, rated at 1,300 kp

PERFORMANCE: 570 mph at 20,000 ft

COMMENT: This night fighter project Me P.1101 NJ (Nachtjäger, Night fighter (or  Me P.1101B-1) was derived from the Me P.1101A-1. It was equipped with Siemens/FFO FuG 218 J3 Neptun interception radar. Although the radar antennae (Hirschgeweihantenne, Stag’s Antlers) was rather small compared those of twin engine night fighters such as Junkers Ju 88C,  Ju 388J-1, or Focke-Wulf Ta 154 the maximum speed was reduced by about 40 mph. This project was never realized.

Messerschmitt Me P.1101A-1 with Kramer X-4 missiles (Dragon)

TYPE: Fighter, interceptor. Project.

ACCOMMODATION: Pilot only

POWER PLANT: Heinkel-Hirth HeS 011, rated at 1,300 kp

PERFORMANCE: 612 mph at 22,970 ft

COMMENT: However, there is some evidence that a further production version of the Me P.1101 was on Messerschmitt’s drawing boards. All over dimensions, turbojet engines, tricycle undercarriage etc. are unchanged to its predecessor, the wing was swept back to 40 degree and a normal or horizontal tail unit – “T-Tail” was provided. Cockpit armor was fitted and up to four Kramer X-4 air-to-air guided missiles could be carried.

RUHRSTAHL/KRAMER X-4

The Kramer X-4 was the first air-to-air guided missile that entered the production lines. It featured a tapering, cigar-shaped fuselage, with four small swept wings and four smaller tail fins. At the ends of two of the opposing wings were small pods which held the wires that unwound during the X-4’s flight. On the wing tips of the other two main wings were simple flares to aid the pilot in keeping the X-4 on the intended path. The tail unit contained small spoilers which could control the missiles pitch and yaw. Power was supplied by the BMW 109-548 liquid-fuel rocket engine with 1,600 kp thrust for 33 seconds. A warhead weighing 20 with a destructive blast radius of 25 feet was mounted in the nose of the missile, being detonated by the pilot, impact or by an acoustical proximity fuse, tuned to the pitch of the bomber’s propellers. First air launched test took place on August, 1944 by a Focke-Wulf  Fw 190. Tests continued through early February 1945, also by Junkers Ju 88s as well as by a Messerschmitt  Me 262 jet fighter with two X-4 missiles under the wings outboard of the jet nacelle, but were not launched  (Ref.: 16).

Messerschmitt Me. P.1101A-0 (Huma)

TYPE: Fighter, interceptor. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Heinkel-Hirth HeS 011 turbojet engine, rated at 1,300 kp

PERFORMANCE: 550 mph at 23,000 ft

COMMENT: Although the Messerschmitt Me P.1101 was from the onset designed as an experimental aircraft different production versions were planned, too. One design was very similar to the Me P.1101 V1 as far as all over dimensions, turbojet engines, tricycle undercarriage etc. are concerned, but the wing was in a fixed position at 40 degree and a horizontal tail unit – “T-Tail” was provided. The unconditional surrender of Germany brought all further work on this exceptional aircraft to an end (Ref.: 16).

Messerschmitt Me P.1079/13 (Unicraft, Resin)

TYPE: Fighter, interceptor. Project

ACCOMMODATION: Pilot only

POWER PLANT: Two Lorin ramjets, rated at 900 kp each

PERFORMANCE: No data available

COMMENT: The P.1079/13 was one of several Messerschmitt designs to meet the Luftwaffe’s late-War request for a small, cheap, single-seat target-defense interceptor. This design included two wing-mounted Lorin ramjets or conventional turbojet engines. For take-off a trolley-launch system was provided and solid fuel rockets were used for acceleration until the ramjets will work. After mission the aircraft landed on a skid. No further details are known.

Messerschmitt Me P.1101/13 (Unicraft, Resin)

TYPE: Fighter. Project

ACCOMMODATION: Pilot only

POWER PLANT: One Heinkel-Hirth HeS 011 tubojet engines, rated at 1,300 kp

PERFORMANCE: 652 mph at 19,658 ft

COMMENT: On July 15, 1944, the RLM submitted Proposal 226/II to Germany’s aircraft manufacturers. This “Emergency Fighter Competition” specified the following requirements for the second-generation of jet-powered fighters: powered by a single Heinkel-Hirth He S 011 turbojet, maximum speed of 621 mph at 22,966 feet, fuel capacity 30 minutes of sea level flying time, altitudes up to 45,931 ft, four MK 108 30mm cannon, and pressurized cockpit. Immediately Messerschmitt began to design the project Me P.1101 and nine days later the first blueprints were on the drawing board. The fuselage was short and wide, the cockpit was forward mounted, with the canopy integrated into the fuselage and forming part of the rounded nose of the aircraft. Two round air intakes on either side of the cockpit fed the single Heinkel-Hirth turbojet engine which was located in the lower rear fuselage. Mid-mounted wings had an inner sweep of 40 degree near the fuselage, and a shallower 26 degree outboard. The high tail was of a butterfly configuration, and was mounted on a tapered boom which extended over and past the jet exhaust. A tricycle landing gear was provided and the main armament of four cannon was located in the lower forward fuselage sides. Already on August 30, 1944, a new design was proposed, basically similar to the Me P.1101/13, but sleeker and a more pointed nose. The wing was “borrowed” from the Me 262 outer wing, was swept back at 40 degrees, and a V-tail was also to be fitted. As early as November 1944 the initial design phase of the final variant was started and simultaneously the construction of a prototype began resulting in the Messerschmitt Me P.1101 V1 (Ref.: 16).

Messerschmitt Me P. 1101/99 (Unicraft)

TYPE: Fighter, ground-attack fighter, destroyer. Project

ACCOMMODFATION: Pilot and observer

POWER PLANT: Four Heinkel-Hirth HeS 011 turbo-engines, rated at 1,300 kp each

PERFORMANCE: 567 mph

COMMENT: The design of another Messerschmitt P.1101 project series, the P.1101/99, dates back to mid 1944. The wings were swept back at 45 degrees, with four Heinkel-Hirth He S 011 turbojets, were buried in the thickened wing roots. Each pair of turbojets was fed by an air intake in the leading edge of the wing. The main landing gear retracted inwards into the fuselage, and the front gear retracted backwards beneath the cockpit. A two man crew sat staggered side-by-side in the cockpit, which was located in the extreme nose of the aircraft. Armament consisted of one 75 mm PaK 40 cannon (PanzerabwehrKanone, anti-tank gun) in the nose and five MK 112 55mm machine cannon, one in the right wing root, four in the center fuselage firing obliquely upwards (Schräge Musik, Oblique or Jazz Music). It was expected that the prototype would be in the air by 1948.  Because of the worsening war situation in Germany, the design did not progress past the drawing board (Ref.: 16).
