Focke Wulf Fw190F Close-support Fighter Aircraft



Technical Description

Low wing cantilever monoplane. Wing in one piece, the front spar being continuous and passing through the fuselage, to which it is attached at three points – two on the upper flange and one on the lower. The rear spar is in two sections, the roots being attached to the sides of the fuselage by normal pin joints. Two spar wing structure with widely-spaced flange plate former ribs, span-wise Z-section stringers and a stressed metal skin. The spars are built up of flanged plates which, inboard from the ailerons, are reinforced by L-section extrusions and progressively thickened end caps to form I-section members. Outboard of ailerons the spars have single integral flanges. The front spar from the points of attachment of the undercarriage to the upper attachments to the fuselage is cranked inward, the undercarriage when retracted lying ahead of the front spar. The gun and undercarriage bays have specially strengthened ribs. Metal framed, fabric covered ailerons. Electrically operated all metal split trailing-edge flaps between ailerons and fuselage.

Fuselage is an all-metal monocoque structure built-up of bulkheads, flanged formers, Z-section stringers and a smooth stressed skin covering. The front inverted U-shaped bulkhead attaches to the upper flange of the front spar and on the front face of the bulkhead and spar are five attachment points for the engine mounting – three on the spar and two on the bulkhead. All other bulkheads and frames conform to the cross-section of the fuselage. The extreme rear section is integral with the fin and is detachable from the main structure. Large detachable panel in the underside of the fuselage extending from the engine bay to rear of cockpit for installation and removal of fuel tanks. The lower part of the engine cowling and the engine covers are fabricated from 6mm armour plate, and additional armour is fitted to the ventral fuselage, the total weight of armour being approximately 380 kg

Cantilever monoplane type tail unit. Fin integral with the rear fuselage. Electrically operated adjustable single-spar tailplane and fin and fabric covered control surfaces. Fixed perforated trim tabs in rudder and elevators. Fin-rear fuselage assembly houses the electric tailplane incidence gear and spring for lowering the tail wheel.

Retractable type undercarriage. Main cantilever oleo-legs are hinged ahead of the front spar and retract inwardly, fairing plates on legs and wheels and on the undersurface of the wings closing the apertures when the wheels are raised. Electrical retraction. The tail wheel is also partially retracted by a cable connected to the starboard oleo-leg. Tail wheel has spring centering and centre-lock, the latter operating when the control column is pulled hard back.

One BMW 801D fourteen-cylinder two-row radial air-cooled geared and supercharged engine in low-drag cowling with induced fan cooling, rated at 1,700 hp for takeoff. The whole engine unit, complete with oil coolers, is attached to the front bulkhead and spar by five bolts. Protected fuel tanks beneath the cockpit floor. Oil tank (42 litres) in fuselage. Reverse flow oil coolers in armoured annual ring which forms the cowl leading edge. VDM airscrew with electric pitch change and metal blades.

Pilot’s cockpit over trailing edge of wing with clear view canopy and tail fairing, the whole of which slides aft to give access to the cockpit and which may be jettisoned complete in an emergency. Pilot’s seat is armoured and is further backed by an armoured bulkhead and headrest, the latter forming part of the jettisonable cockpit canopy. Bullet proof windscreen. The wireless aerial lead is in the roof the canopy. The canopy cannot be opened in the air except to be jettisoned. Armament comprises two 13mm MG131 with 220 rounds of ammunition in the forward fuselage decking and two 20mm MG201 with 150 rounds of ammunition per gun , located in the wing roots and synchronised to fire through the propeller arc. Attachment point beneath the centre section of the wing for one bomb up to 1,000 kg weight or for one 240-litre jettisonable auxiliary fuel tank; attachment points beneath each wing outer panel for bombs and air-to-ground rockets.

Junkers Ju288A Medium Bomber Aircraft



Technical Description

Shoulder wing cantilever monoplane. Structure in three sections, the centre-section which incorporates a portion of the fuselage and the two outer sections with semi-circular wing tips. Two-spar wing structure. All but a few former ribs are girder trusses, solid plate ribs being used at points of stress only. Smooth outer stress-bearing skin riveted to spars and former ribs. Slotted ailerons on outer sections. Electrically operated split flaps. Maximum flap angle 55 degrees. Ailerons and flaps are linked so that the ailerons droop when the flaps are lowered. Leading edge of the outer wing-section is double skinned and intervening space fed with hot air through lagged pipes in leading edge. Air enters at bottom of the sandwich between each nose rib and passes forward and upward around the leading edge and escapes into wing just forward of the front spar flange and finally to the atmosphere through apertures at the aileron hinges.

Fuselage is an all-metal structure in three sections, comprising the nose section accommodating the crew, the section which is integral with the wing centre-section section and the rear fuselage. Main structure is built up of a number of formers and stringers to which the stressed skin is riveted.

Cantilever monoplane type tail unit with twin fins and rudders. Tailplane and fins each have two spars and the entire unit, including the movable surfaces, is covered with a metal skin. Fins are fitted with fixed slats, the trailing-edges of the slats being on the inside of the fins. Rudders have very narrow horn balances, used mostly for mass balancing, and trimming tabs extending the full length of the trailing edge. Tailplane incidence is automatically changed when the landing flaps are lowered. It can also be adjusted manually.

Retractable type undercarriage. Each unit comprises two oleo legs and a single wheel and is electrically retracted rearwards into the engine nacelle. Electrically operated retractable tail wheel.

Two BMW 802A eighteen-cylinder two-row radial air-cooled engines each rated at 2,560 hp for takeoff and 1,575 hp at 11,800 metres on welded steel-tube mountings at the extremities of the centre-section. Five self-sealing fuel tanks and two oil tanks in the wings between the spars. Carbon-dioxide gas may be released into tank compartments in emergency. VDM four-bladed fully-feathering airscrews.

The crew of three is located in a pressurised cabin forming the forward section of the fuselage. The bomb aimer sits in the forward portion of the cabin, and his position is provided with duplicate controls for the aircraft; the pilot sits in the second position, while the wireless operator air gunner sits behind the pilot.

Design History

Work on the Fa300 began in November 1941 in the wake of the Ivry-sur-Seine gathering of rotary wing designers. Inspired by the paper delivered by Igor Sikorsky Doctor Heinrich Focke and Gern Achgelis began work on a single-rotor design with tail rotors to provide stability. By May 1942 a prototype had been constructed, which, while successful in a technical sense, required considerable improvement before it could be considered a viable alternative to the Flettner Fl282 or to the Focke Achgelis Fa223. Work was further disrupted by the departure from the Focke-Achgelis collective of Raoul Hafner, who chose to continue the collective’s work on twin rotor designs.

In June 1943 the Luftwaffe placed orders for four machines for purposes of evaluation, two of which will be used to evaluate the design’s potential as a search-and-rescue aircraft while the second pair will be tested by the Heer for army-cooperation tasks.

Bayerische Flugzeugwerke Bf329 Interceptor



Development of this aircraft was pursued as a joint Russo-German venture, with Hans Multhopp and Semyon Lavochkin leading the design and development team. The design was begun in 1943 with the intent of producing a fast, high-climbing interceptor; progress was plagued with trouble, with the first prototype disintegrating during a test flight in eastern Germany. Work was then moved to the Lipetsk test station in Russia, where the airframe was redesigned to address structural issues. Further delays were incurred due to lack of power from the intended powerplant – the BMW003, necessitating the switch to the Heinkel HeS011. The revised design made its first successful flight in September 1946, with an expected service introduction sometime in 1947.
