POWER PLANT: One Rolls-Royce Griffon inline engine, rated at 1,730 hp, and one Whittle W.1A turbojet engine, rated at 390 kp
PERORMANCE: No data available
COMMENT: In 1939 the British Air Ministry issued Specification F.18/37 for a heavily armed interceptor. Beside the Bristol Aircraft Company, Gloster Aircraft proposed a design that, a novelty at that time, was to be powered by a Rolls-Royce Griffon piston engine and additionally by the brand new Whittle W.1A turbo engine. At least Hawker Aircraft Company submitted the best design that later became the Hawker Tornado. So in 1940 development of the Gloster Boosted Fighter was cancelled.
POWER PLANT: Two Junkers Jumo 004B turbo-jet engines, rated at 890 kp each plus two Lorin ram-jets, rated at 1,350 kp each
PERFORMANCE: 714 mph (estimated)
COMMENT: Dr. E. Sänger, a convinced supporter of ram-jet powered aircraft, e. g. Skoda-Kauba SK P. 14-01 and SK P.14-02, proposed to increase the performance of a Messerschmitt Me 262 by integrating two additional Lorin ram-jets. The ram-jets, each 5.90 m long, were mounted above the wing resp. the turbo-jet engines, the air intake was 45.1, and the exhaust pipe 85 cm in diameter, respectively. It was calculated that the Me 262 could reach 48,557 ft within 11.5 minutes. Finally, this project was not pursued (Ref.: 19)
POWER PLANT: Three × General Electric J-47-GE-13 turbojet engines, rated at 2,700 kp each
PERFORMANCE: 645 mph
COMMENT: In early 1945, USAAF issued requirement for a new attack bomber for low-level bombing and close support as a successor to the Douglas A-26 Invader. Martin Company proposed its design and won the competition with designation, XA-45. Soon later USAAF revised its requirement for better close-support bombing. Martin accepted the new requirement and was received contract for two prototypes, the project was redesignated XB-51. The first XB-51 made its first flight on Oct 1949. The aircraft was powered by three jet engines: one at the extreme tail with an intake at the base of the tailfin, and two underneath the forward fuselage in pods. The innovative, variable incidence wings were swept at 35° and with 6° anhedral. The main landing gear consisted of dual sets of wheels in tandem in the fuselage with outrigger wheels at the wingtips. Crew provision was for a pilot under a “fighter”-type bubble canopy and for an operator/navigator in a compartment located lower than and to the rear of the cockpit. It became the fastest ground support bomber at the time. Although test flights were satisfying Martin XB-51 never went into production. Noteworthy is the fact that the design can be traced back to a German WWII-project Messerschmitt Me P.1102/105 that was to be powered by three Heinkel-Hirth HeS-109-011 turbo-engines, one in the extreme tail and two in pods under the extreme forward fuselage and provided with variable-sweep wings, too (Ref.: 24)
POWER PLANT: One Mitsubishi Ha-211 Ru radial engine, rated at 2,200 hp
PERFORMANCE: 454 mph at 32.810 ft
COMMENT: In 1943 Mansyu offered the Japan Army Air Force a project of a single-seat ground attack aircraft designated Ki-98. The design was of twin boom configuration and was powered by a 2,200 hp turbosupercharged Mitsubishi Ha 211 Ru radial engine mounted in the central nacelle behind the pilot’s seat and driving a four-blade pusher propeller. Nose-mounted armament consisted of one 37 mm and two 20 mm cannon. A prototype was still under construction when Japan surrendered in September 1945 (Ref: 1)
POWER PLANT: One Napier Sabre II liquid-cooled engine, rated at 2,020 hp
PERFORMANCE: 415 mph at 20,000 ft
COMMENT: In early 1942 the British Air Ministry issued specification F.18/39 that called for a single-seat fighter with a maximum speed of not less than 400mph at 15,000 ft, a service ceiling of not less than 35,000 ft, a fuel capacity sufficient for thirty minutes at maximum power, two hours at economical cruising speed plus thirty percent reserves, and a loaded weight not exceeding 12,000lb. To meet these requirements, the Martin-Baker Aircraft Company designed an aircraft, M.B.3, with remarkably strong structure, a phenomenally heavy armament, and good handling qualities. Two prototypes of the M.B.3 were ordered and the first of these was flown on August 1942. Trials indicated that the prototype was extremely maneuverable and processed excellent handling characteristics. On September 1942, during landing approach, the Sabre engines failed and the aircraft was completely destroyed. Construction of the second prototype, powered by a Rolls-Royce Griffon engine and the designation M.B.4 was abandoned in favor of an extensively redesigned model, the Martin-Baker M.B.5(Ref.: 12)
POWER PLANT: Two Junkers Jumo 004B turbojet engines, rated at 900 kp each
PERFORMANCE: No data available
COMMENT: In early 1943 during a conference led by the RLM it was proposed to reconstruct a Messerschmitt Bf 109 into a jet powered fighter. Because the airframe of the Bf 109 was not suited for such a modification it was decided to use the fuselage of a Messerschmitt Me 109H high-altitude fighter, the undercarriage of the Messerschmitt Me 309, and the wing of the projected Messerschmitt Me 409. Nevertheless, soon it became clear that too many parts had to be changed so after two month the project was cancelled (Ref.: 19).
POWER PLANT: One Pratt & Whitney R-2800-10W Double Wasp radial engine, rated at 2,000 hp
PERFORMANCE: 380 mph at 23,400 ft
COMMENT: In Mid 1944 an improved and refined version of the famous Grumman F6F-3, the Grumman F6F-5 “Hellcat” rolled out of a brand new factory, especially built for this reason. The Pratt & Whitney engine with water injection was retained, but the cowling was modified and the windshield was improved. Provision was made for 2,000 lb of bombs under the center section and six rockets under the outer wing. Production of this version totalled 6,681 aircraft plus 1,189 F6F-5N’s night fighter with APS-6 radar in the pod of the starboard wing. The aircraft shown here was on board of USS CV-15 “Randolph” in March 1945 (Ref.: 22)
POWER PLANT: Two radial engines, type not available
PERFORMANCE: No data available
COMMENT: Poorly documented JAAF-project of a light bomber with twin fuselage, two radial engines and pilot and gunner/radio-operator seated in the left fuselage. Similar designs during World War II were in Germany Arado E,580 (project), Messerschmitt Me 109Z (flown, Z for Zwilling = twin), Messerschmitt Me 609 (project), Dornier Do 635 (Junkers Ju 8-635) (project),and Heinkel He 111Z (flown), and in the United States North American P-82 (flown).
POWER PLANT: Two Rolls-Royce Merlin III engines, rated at 1,030 hp each
PERFORMANCE: No data available
COMMENT: Prior to WWII, the major world powers knew they needed long-range fighters to escort their bombers deep into enemy territory. To this end, the British aircraft company Martin Baker submitted an innovative design for a tailless, twin-engine fighter armed with 12 heavy machine guns. Its rudder gone to help reduce drag, the plane would use the trailing ends of its engine nacelles for lateral control supplemented with ducted engine exhaust gases as well as propeller induced air stream. Although seriously evaluated by the RAF, the Martin Baker 12 Gun Fighter never made it past the design stage.
POWER PLANT: Two BMW 801D radial engines, rated at 1,750 hp each and two Junkers Jumo 003 turbo-jet engines, rated at 880 kp each
PERFORMANCE: 571 mph
COMMENT: This Blohm & Voss project from 1944 was designed as a general purpose/long-range fighter. The wing was straight and unswept, with the section between the two engine nacelles being thicker and having increased chord, to house the main wheels of the tricycle landing gear. Two BMW 801D radial engines were mounted at the forward end of the nacelles, and two Junkers Jumo 004 turbo-jet engines were located in the rear of the nacelles. Provision was made for use of other turbo-jet engines, e.g. BMW 003 (Bv P. 203.2) and Heinkel-Hirth HeS 011 (Bv P. 203.03) The aircraft was heavily armed including a remotely controlled twin MG 131 13mm machine guns in the tail firing to the rear. Due to the “Jägernotprogramm” (Fighter-emergency-programme) all work was cancelled (Ref: 23)
