Arado Ar 234 (Blitz)

History

Just as the German Messerschmitt Me 262 "Schwalbe" ("Swallow") had the honor of being the world's first operational jet fighter, the Arado Ar 234 "Blitz" ("Blitz") was hailed as the world's first operational jet fighter Recognized jet bomber. Introduced in 1944, the system entered service in 1945 and remained in service until the end of the war in 1945. It proved to be one of the most technologically advanced and valuable weapons of the Luftwaffe, but never reached the required number.

In fact, the aircraft proved so advanced that it was able to evade all Allied interceptors available at the time, making it a very capable reconnaissance and high-speed bombing platform. Unfortunately for the Germans, the associated testing and manufacturing facilities were continually disrupted, fuel supplies were cut off, the factory was eventually overwhelmed by the advancing Allied front, and production was limited to a few hundred by the end of the war.

The West seems to have benefited the most from the captured technology, especially the Americans who designed, developed and produced several Cold War-era jet bombers that were ostensibly similar in some respects to the war-time Ar 234 series (though generally on a larger scale). ). The Ar 234 became the second Luftwaffe jet to enter service after the famous Me 262.

Germany's dilemma

The origins of the Ar 234 can be traced back to an original program of the German Aviation Ministry (RLM = Reich Aviation Ministry) in the late 1930s, which called for a new high-speed reconnaissance platform for the Navy. So far, the Germans have relied on a series of seaplanes and airships for this role, although the performance of these machines is far from excellent (aside from their inherently excellent range).

These aircraft are extremely vulnerable to enemy interception because they lack the performance and maneuverability needed to evade incoming threatsespecially the types of maneuverable fighters used by the Allies.

Department of Air Force Requirements

In the fall of 1940, the Air Department approved a new design that would fly higher than enemy defenses could reach, and fly faster than enemy aircraft could intercept. The optimal combat radius is 1,240 miles, and the maximum ferry range is at least 1,340 miles. This requirement was specific to turbojet designs, although the technology was still in its infancy at the time.

Officials understand the potential forces behind turbojet technology and its revolutionary impact on the military aviation community, and believe this is the best place to start. Brands such as Junkers and BMW are already developing such engines.

In any event, the turbojet-powered aircraft would bring it to full compliance with the Air Ministry's specifications, although this would pose a significant technical challenge to the German engineers involved.

Commitment of E. 370

The Arado Group was the only responder to the fast reconnaissance bomber design. The company has a proven pedigree with a steady stream of talented engineers running the program - led by Walter Blume, who ran Arado until its collapse in 1945. Along with Hans Rebeski and Rudinger Kosin, he is considered the official concept for the Ar 234. Arado completed and submitted his formal proposal in 1941, and the aircraft developed was designated "E.

370". After receiving official approval from the Luftwaffe, the design was dubbed the "Arado Ar 234". Subsequently, the Air Department commissioned six prototypes in April 1942 to further demonstrate the viability of the design. By the end of the year, the total number of orders had increased to 20. Two complete airframes were built from late 1941 to 1942, although the Junkers Jumo engine was not available until 1943, causing serious delays to the serial production schedule originally scheduled to begin later that year.

Therefore, the Ar 234 did not enter service until February 1943.

Arado Ar 234 Tour

The Arado Ar 234 used a very unique flat form, one of the most recognizable of all wartime jet designs. The fuselage is pencil-shaped, with a rounded nose cone and a tapered stern. The entire nose consists of a single-seat cockpit, which provides an excellent view of oncoming action, involving only the light frame. Only rearward visibility is blocked by the integrated fuselage spine, which runs its entire length to form the tail. The rounded hull incorporates plate sides for internal fuel storage, avionics, and deep approaches required for the cockpit.

The engines are housed in a streamlined nacelle, with the base Ar 234 model having one engine per wing. The wings themselves are straight attachments mounted high on the sides of the fuselage.

The rear wing consists of a curved vertical rear wing with two horizontal planes mounted above the main wing panel. On the final B model, the landing gear was fully retractable and arranged in a tricycle form with two main gear legs and one front leg.

All three positions contain a large low-voltage "doughnut" landing gear designed to offset the rather narrow landing gear track.

Without Landing Gear

The original Ar 234 prototype lacked a full tricycle landing gear, hampered by the design of a thin fuselage whose bulk was already occupied by a large number of other essential equipment, mainly fuel storage required for long distances. As such, the vehicle was launched from a throwaway trike (complete with steerable nose and wheel brakes) that mimicked the final landing gear. Landing will take place via slides mounted on the aircraft's belly and below the engine nacelles. The first turbojet Ar 234 prototype finally made its maiden flight from Rhine Airport on July 15, 1943, with five more prototypes following the first V1.

Of the six cars initially completed, two were reserved as static test beds for the upcoming four-engine development.

Arado Ar 234A and V prototypes

The Ar 234 series is built through a series of evolving prototypes, starting with V1.1. Prototypes V1 to V5 used a trolley system for takeoff and landing taxi recovery. All powered by Junkers Jumo 004 turbojets. The V1 made its first flight on June 15, 1943.

The V3 is equipped with an ejection seat and a pressurized cockpit, as well as an auxiliary launch rocket. The V6 and V8 prototypes were four-engine developments, resulting in the Ar 234C model described below. The V6 prototype managed the installation of its 4 x BMW 003 engines via four separate nacelles, while the V8 relied on paired nacelles in two pods, one on the wing.

The V7 was the main development on the Ar 234B line, although it retained the dolly skid arrangement. The V9 to V11 prototypes introduced traditional powered tricycle landing gear through a deeper fuselage design. These also lead to Ar 234B. The V13 and V20 were the four engine developments that influenced the Ar 234C series, with 4 x BMW 193-003 engines in paired nacelles.

The V20 was lost in the Allied bombing of Wessendorf on April 4, 1944. The V15 is a single-engine test bed for 2 x BMW 003 turbojet engine units. The V16 was developed around a crescent wing, although their test facility was occupied by the British Army before the aircraft was completed, and the project was destroyed in the ensuing battle. The V19 first flew on September 30, 1944.

The prototypes V21 to V30 further developed the C-model series. The V26 and V30 are especially known for using laminar vane arrangements.

The first early, near-series form was the Ar 234A, which was essentially a V1 to V8 prototype with their dolly/skid undercarriage.

Arado Ar 234B

Landing gear issues were addressed starting with V9, Ar 234B-0 representing 20 pre-production units, last example completed in June 1944. The original Ar 234B-0 brand first aired on June 8. However, in 1944, there were no planned cockpit pressurization and ejection seat features. The Ar 234B-1 is an unarmed reconnaissance version with a camera.

The Ar 234B-1 can supplement the promised autopilot function and operate with auxiliary fuel tanks for greater range. The Ar 234B-2, the bomber version with a storage capacity of 3,300 pounds, entered service in late 1944 and remained in service until 1945. Rauchgerate Rocket Assisted Takeoff (RATO) can be used to predict faster takeoff times and shorter runway distances, as well as amazing initial climb rates - useful in flares.

Long landings can then be compensated for by braking the parachute. Some Ar 234B-2 models were equipped with radar and a ventral gun pack with a second rear cockpit for night fighters. The design proved to be aerodynamically efficient and relatively stable, requiring few engineering fixes. That's how solid the Model B will be in the near future, the standardized form of Ar 234. These versions introduced ejection seats, the Patin PDS autopilot system and, due to demand from earlier turbojets, received an optional external auxiliary fuel tank for improved range.

The cockpit is fully pressurized to match the high altitude at which the Ar 234 must operate if onboard oxygen supplies and supplies are required. These models will be powered by 2 Junkers Jumo 004B series turbojets.

The Ar 234B series models became the final operational-grade, production-quality mounts for the entire "Blitzkrieg" series that entered service in 1945.

Only two B-types were used in combat - the unarmed reconnaissance platform Ar 234B-1 and the special bomber Ar 234B-2. The B-2 is further subdivided into sub-variants such as the Ar 234B-2/1 ("Pathfinder") target marking platform, the Ar 234B-2/b dedicated reconnaissance and the Ar 234B-2/r tank. auxiliary fuel.

Ar 234B production is 210 units. The Ar 234B-3 was originally intended as a dedicated bomb platform, but was eventually abandoned with the advent of the Ar 234C described below.

Arado Ar 234C

The Ar 234C was born to meet the need for more power. As such, the C models are largely based on the previous B model brands, although they were developed to maximize the overall airframe. The Ar 234C-1 started the C model series with 4 BMW 003 series turbojets. Another notable difference from the Ar 234C model is the elevated cockpit for better visibility into upcoming action.

The cockpit also receives fewer frames, improving situational awareness. These are based on the prototype Ar 234 V8 and influenced by the Ar 234 B-1 production line. The Ar 234 C-2 succeeded the Ar 234 B-2, but had four engines instead of the original two. The Ar 234 C-3 is a multipurpose model with 2 x 20 mm MG 151/20 series cannons mounted under the nose.

The Ar 234 C-3/N is a C-type night fighter with a radar and a second cockpit. Armament consists of 2 x 20mm MG 151/20 cannons in fixed forward position and 2 x 30mm MK 108 cannons.

The Ar 234 C-4 is an armed reconnaissance variant with two cameras and 4 x 20mm MG 151/20 cannons, capable of reaching a top speed of 550 mph when lightly armed. The Ar 234 C-5 is a side-by-side cockpit reconnaissance aircraft developed from the V28 prototype. The Ar 234 C-6 is another proposed reconnaissance variant with two seats, based on the V29 prototype. The Ar 234 C-7 is a proposed night fighter with side-by-side seats and radar, powered by 4 Heinkel Hirth He SO11 engines.

The Ar 234 C-8 is a proposal for a single-seat bomber with 2 x Junkers Jumo 004D turbojets. Some brands of rear-firing guns are controlled by a cockpit periscope (adopted from German tanks), viewing the rear quadrant of the aircraft in real time.

Arado envisioned no less than eight C-type variants, although the end of the war dashed those plans.

The Ar 234C-2 is also being considered for towing the Henschel Hs 294 guided missile, or, in its place, the single-seat suicide rocket-propelled missile Fieseler Fi 103 - a manned evolution of the famous V1 rocket. Terror" weapon. The Fi 103 would sit on the back of the fuselage and release via a hydraulic arm to attempt to release the tail rudder during takeoff. In a further design evolution, the Fi 103's warhead, propulsion system and guidance components were removed, leaving An undercarriage was added with wheels for ground travel that served as a "drag tank" that was dropped when it was dropped from its mother ship, Ar 234.

The move stemmed from a tow bar tow test.

The attack continued in January, when Ar 234 conducted airstrikes against all possible targets in Belgium. In turn, limited fuel supplies ended up limiting flight time and keeping a more powerful Luftwaffe aircraft on the ground.

The last recorded flight of the Ar 234 was in March, when the plane attempted unsuccessfully (for ten days) to destroy the Rhine bridge in Remagen. By the end of the month, the bridge was in American hands.

Despite the increasing numbers, the Ar 234 was not enough to fly, and the official collapse of Germany in May 1945 terminated all future operations.

End of the road

1945 was a pivotal war year for all parties. The Allies to the west and the Soviet Union to the east made steady progress in German-held territory. As the circle of Adolf Hitler's trusted generals and henchmen dwindled, an air of desperation spread from the German camp. When the Allies discovered the existence of Ar 234, they sought out completed examples to capture. Several efforts were unsuccessful until February 25, 1945, when two Republic P-47 Thunderbolts managed to flank one-engined production Arado Ar 234B-2 models over Segelsdorf.

The plane was forced to make a wheeled landing and landed unscathed despite its proximity to the still-disputed German-American front. After heavy fighting - the Germans trying to preserve their technology and the Americans trying to steal it - the fuselage was protected by the US 9th Army, only to be disassembled and taken to the UK for inspection.
