Focke-Wulf Super Lorin with Kramer X-4 (Unicraft, Resin)

TYPE: Interceptor, fighter. Project.

ACCOMODATION: Pilot only

POWER PLANT: Two Lorin ramjet engines, rated at 1.500 kp each (estimated) plus one Walther WHK 109-509A liquid-fueled rocket engine, rated at 1.700 kp

PERFORMANCE: 680 mph in 36090 ft (estimated)

COMMENT: Very little is known about this project, which was designed around the same time as the Focke-Wulf Fw Ta 238. The “Super Lorin” featured sharply swept back wings which were mounted mid-fuselage. There were two ramjets mounted at the tips of the swept back tail plane, this was thought to minimize airflow disturbance. Since ramjets do not begin to operate until a speed of approximately 150 mph is reached, Schmidding solid- fueled or Walter WHK 109 liquid-fueled rockets were proposed to accelerate the aircraft until the ramjets could begin operating. The landing gear was to be a tricycle arrangement, and armament would have been two MK 108 30mm cannon. The aircraft shown here is fitted with two Ruhstahl/Kramer X-4 guided missiles. (Ref.: 16).

Messerschmitt Projekt “Schwalbe” I (Unicraft, Resin)

TYPE: Interceptor, fighter, fighter bomber. Project

 ACCOMMODATION: Pilot only

 POWER PLANT: Two Junkers Jumo 003B turbojet engines, rated at 900 kp each

 PERFORMANCE: 580 mph, estimated

COMMENT: The Messerschmitt “Schwalbe” (Swallow), not to confuse so to the  Messerschmitt Me 262 “Schwalbe”, was a late-war design that did not receive a project number designation. The wings were swept back at 31.5 degrees, and contained the majority of the fuel supply. The wings seem to have been based on the Messerschmitt Me 163 or Me 263 (Ju 248) wing design, as there is more than a superficial resemblance. Two turbojets were proposed, one was located above the fuselage and one below. A tricycle-type landing gear design was chosen, with the nose wheel retracting to the rear and the two main gear retracting forward and inboard. The cockpit was located in front of and between the upper air intakes. An especially curious feature is the device at the fuselage rear; this is thought to be dive brakes or some sort of thrust reversal mechanism (Ref.: 16).

Junkers Ju-187 (Unicraft, Resin)

TYPE: Dive-bomber and close-support aircraft. Project

ACCOMMODATION: Pilot and rear gunner/observer

POWER PLANT: Junkers Jumo 213 A-1, rated at 1,750 h.p.

PERFORMANCE: Not available

COMMENT: Needed as replacement for the shortcoming Ju 87, the design was faster, better armored and had a greater bomb load. The most unusual feature was the movable tail fin. In order to clear the field of fire for the remote-controlled rear turret the whole tail plane could be turned downwards by 180 degree. Although a full sized mock-up was built the OKL preferred the Focke Wulf Fw 190 as close-support fighter bomber

Blohm und Voss Bv P.207-02 (Unicraft, Resin)

TYPE: Fighter bomber, ground support aircraft. Project

ACCOMODATION: Pilot only

POWER PLANT: One Junkers Jumo 213 inline engine, rated at 1.800 hp

PERFORMANCE: Not available

COMMENT: This fighter design used a Junkers Jumo 213 buried in the fuselage just behind the cockpit. The air intake was located beneath the fuselage and the pusher propeller was driven by means of a long shaft. The rectangular wing was mounted at the bottom of the fuselage and had no sweep back or taper. The tail unit was of cruciform design and a tricycle undercarriage was fitted. Proposed armament was two MK 103 30mm cannon and two MG 151/20 20mm cannon located in the nose. A refined design was the Blohm & Voss Bv P.207/03 where the upper fin and rudder were deleted. But neither the BV P.207/2 or /3 proceeded past the design stage (Ref.: 16).

Blohm & Voss Bv. 237 (Unicraft, Resin)

TYPE: Dive bomber, ground attack fighter. Project

ACCOMMODATION: Pilot only

POWER PLANT: One BMW 801D radial engine, rated at 1,700 hp

PERFORMANCE: 360 mph

COMMENT: The Blohm & Voss Bv 237 was a proposed dive bomber with an unusual asymmetric design based on the Blohm & Voss Bv 141, as well as other projects like Bv P.194 and Bv P.204. In 1942 the Luftwaffe was interested in replacing the venerable but ageing Junkers Ju 87, and Dr. Richard Vogt’s design team at Blohm & Voss  began work on project P 177. The dive bomber version would have had a one man crew and was heavily armed with cannon, machine gun and bombs. A two seat ground attack version was also proposed. A final B-1 type was to incorporate a Junkers Jumo 004B  turbojet engine in a third nacelle slung underneath the wing, between the piston engine and the cockpit. In early 1943 a production order was issued for the P 177 now called the Bv 237. In the summer that year the RLM ordered all developmental work stopped. Work continued later and it was determined that construction could begin in mid 1945, but plans for a pre-production A-0 series were abandoned, leaving the project at the pre-production stage near the end of 1944, with only a wooden mock-up completed (Ref.: 23).

Blohm & Voss Bv P.211.01 (Unicraft, Resin)

TYPE: Interceptor fighter. Project

ACCOMMODATION: Pilot only

POWER PLANT: BMW 003A-1 turbojet, rated at 800 kp

PERFORMANCE: 536 mph at 26,250 ft (estimated)

COMMENT: Design of an interceptor fighter from mid 1944, forerunner of the Bv P.211.02, that was submitted for the “Volksjäger” (Peoples fighter) competition. Winner was the Heinkel He 162 “Spatz”.

Heinkel He 343B-1 (Airmodel, Vacu)

TYPE: Heavy fighter, medium bomber.  Project.

ACCOMMODATION: Pilot and observer

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

PERFORMANCE: 565 mph

COMMENT: The Heinkel He 343 was a four-engine jet bomber project by Heinkel Aircraft Company in the last years of WW II. In 1944 a total of 20 of these aircraft were ordered. For shortening the development time and for re-use of existing parts, its general design was envisioned along the lines of an enlarged Arado Ar 234 “Blitz” (“Lightning”). For a choice of engines, the Junkers Jumo 004 and the Heinkel HeS 011 were planned. The DFS (Deutsche Forschungsinstitut für Segelflug),  (German Research Institute for Gliding Flight) was involved in the project and created the project known as P.1068. By the end of 1944, work was nearly finished by the Heinkel engineers, with parts for the He 343 prototype aircraft either under construction or in a finished state, when the order was cancelled due to the “Jägernotprogramm (Emergency Fighter Program). Four versions were planned: the He 343A-1 bomber, the He 343A-2 reconnaissance aircraft, and the He 343A-3 and He 343B-1 Zerstörer (“Destroyer”) heavy fighters.
The Heinkel He 343B-1 differed from the He 343A-1 bomber version especially in the tail unit. Instead of the two fixed rear firing guns in the fuselage rear, a FHL 151Z remote controlled turret was installed in the extreme rear fuselage. This necessitated a tail redesign to a twin fin and rudder set up. A rear facing periscope in the cockpit was used to aim the FHL 151Z turret, which was armed with two MG 151 20mm cannon. The twin tail would have made for extended flight testing, plus would have added additional weight and drag (Ref.: 17, 24).
