Ryan XF2R Dark Shark

History

The Ryan Black Shark was an impressive hybrid fighter design that was considered for service in the U.S. Navy and U.S. Air Force shortly after World War II. The aircraft attempted to combine a turboprop unit with a turbojet to achieve excellent performance specifications at a time when the turbojet lacked the necessary power and long-term reliability to power a fighter jet - especially on the short deck of an aircraft carrier superior.

Advances in jet propulsion, however, put an end to this hybrid design, and the Black Shark could only exist in one prototypethe U.S. Navy and U.S. Air Force's interest waned when tempted by dedicated jet power. Power fighters for their nascent squadron.

At this point in aviation historythat is, spanning the period late in World War IIearly turbojets lacked power and were basically the thirsty breed. While they offer some inherent advantages over most conventional piston-engined aircraft, they are relatively new in utilizing the technology, a testament to the fact that some government organizations are considering comparing proven piston-engine technology to turbojets.

The option to combine to make up for its shortcomings is justified. This movement led to a brief period of experimentation with hybrid concepts in the history of military aviation, although very few aircraft were produced - the jet age had advanced enough in the early 1950s to allow true jets to dominate the traditional piston power type.

Ryan Aeronautical Company has previously attempted to build a hybrid aircraft for the US Navy in its FR Fireball. It proved to be a short-lived combat platform, using a piston engine and a turbojet to achieve combined thrust performance (and thus significantly improved performance specifications), rather than just using either type of mounted aircraft. Aside from the hybrid engine arrangement, the Fireball is primarily a conventional aircraft mounted on a retractable powered tricycle landing gear. Power comes from General Electric J31-GE-3 series turbojets linked to Wright R-1820-72W Cyclone radial piston engines - each delivering 1,600 lbf of thrust or 1,350 hp. She was flown by a pilot in the front cockpit, and about 66 prototypes were produced from 1944 to 1945, the last year of World War II.

However, the end of the war meant the end of the need for the Fireball and the end of production - it formed only one squadron in its brief service with the US Navy and was taken out of service in late 1947.

The US Navy has considered another Ryanair development, the improved XF2R Black Shark, as a possible addition to its shipboard product portfolio. Design-wise, it proved to be thinner and lighter than the Fireball, and also featured a hybrid engine arrangement, although the basic piston engine was replaced by a turboprop.

The cockpit is more concentrated in the beautifully contoured fuselage, with the four-blade propeller engine located at the front of the design, while the turbojet is hidden behind the fuselage. The rear wing is traditional, and the Black Shark is also carried by the tricycle landing gear.

A prototype was officially ordered and made its first flight from Edwards Air Force Base on November 1, 1946. Essentially, the Black Shark is an evolution of the Fireball concept, but with a new airframe design and the introduction of a turboprop engine.

GE was responsible for the two engines and installed the J31 series turbojet and T31 turboprop. The J31 also powered the Bell P-59 Airacomet and Ryan FR Fireball, America's first jet fighter, and became the first mass-produced jet engine in the United States, although it originated in Whittle, England, with the W 1 series. The propeller-oriented T31 turboprop continued to power the obsolete Vultee XP-81 (of which only two prototypes were built) and never reached true production numbers (28 in total). However, this type became the first turboprop to be mass-produced in the United States. The J31 provides 1,600 pounds of thrust in the push motion, while the T31 adds 1,760 horsepower to the airframe towing.

When these engines work together in the Black Shark, they give the fighter a top speed of nearly 500 mph, a service ceiling just under 40,000 feet, and a rate of climb of 4,850 feet per minute. The engine is supplied with air through air intakes on the leading edge of the wing.

Compared to the legendary WWII North American P-51D Mustang fighter, the Black Shark surpassed its listed performance figures of a top speed of 437 mph and a rate of climb of 3,200 ft/min.

Like most other heavy hitters who served the Americans during the war, the Black Shark was armed only with large-caliber machine guns - contrary to the accepted standard for large-caliber machine guns found on British, German, and Soviet aircraft. be found . The Black Shark will be armed with 4 x 12.7mm (0.50 caliber) Browning M2 heavy machine guns. Machine guns offer higher rates of fire and larger ammunition loads than competing cannon systems. Aside from machine gun batteries, the Black Shark has no other designated weapon options.

In contrast, the P-51D Mustang was armed with 6 x 12.7mm machine guns in the wings and a bomb-carrying device in the strike range.

While reviews found the Black Shark to be a solid aircraft design in many respects, advances in jet technology hindered further development of the genre. Additionally, the Dark Shark's performance numbers were no higher than previous Fireball attempts, prompting the U.S. Navy to procure jets with increasingly powerful engines, while the Dark Shark was only in scrapped prototype form. The U.S.

Air Force also showed interest in Ryan's creation, but chose to pursue a pure jet fighter on its own. However, the single dark prototype was slightly modified by the USAF to use the Westinghouse J-34 series turbojet and became the "XF2R-2" prototype. To attract the new engine, the original XF2R's intake ducts were redesigned to include two side-mounted intakes, and the original's leading-edge wing intakes were completely removed from the design.

This new designation resulted in the former Black Shark being identified as "XF2R-1" from now on.
