Curtiss P-40 Warhawk

Curtiss P-40 Warhawk

The 1944 Curtiss P-40 was conceived as a pursuit aircraft and was agile at low and medium altitudes but suffered from a lack of power at higher altitudes

The single-seat Curtiss P-40 Warhawk was obsolete when it was drafted for service at the start of World War II. But it was the best fighter that the United States had available in large numbers, according to a report at the Museum of Flight. Despite continued improvements, the P-40 never equaled the capabilities of its German or Japanese adversaries. But it had one priceless advantage, “It was available and being efficiently mass-produced when needed most.”

The solid and reliable Warhawk was an effective weapon when its strengths were leveraged: diving passes and rapid departure without engaging in a turning dogfight with more agile opponents.

According to Airplane-Online.com, the P-40 was a descendant of the “Hawk” line produced by the Curtiss-Wright Aircraft Corp. in the 1930s and 1940s. It shared certain design elements with its predecessors, the Hawk and Sparrowhawk.

The all-metal fighter was first flown in 1938, and the P-40 was kept in production until 1944. The P-40 was the third most-produced American fighter, after the P-51 Mustang and P-47 Thunderbolt.

Warhawk in Wartime

With its six .50-caliber Browning machine guns and a 700-pound bombload (one 500-pound and two 100-pound bombs), the P-40 served in all theaters of operation. The U.S., Britain, Canada, Australia, New Zealand, Free French, South Africa, and Russia flew the Curtiss fighter.

“The British called it the Tomahawk (B and C models) and Kittyhawk (D and E models). The F through R versions were known as Warhawks in U.S. service. The N model had decreased fuel capacity and increased armor, along with other minor system changes, relative to its predecessors.

“The most famous P-40 unit was undoubtedly the American Volunteer Group, better known as the ‘Flying Tigers.’ Painted with a shark-mouth face, the P40 had great success flying the plane in China and Burma in early 1942.

In the hands of a skilled pilot, the P-40 could exceed its limitations and out-maneuver and out-fight anything in the sky, Flying Tiger ace David L. “Tex” Hill said in 2005 interview for DefenseMediaNetwork.com.

“It was sturdy and handled well, except in a spin, but you never piloted a P-40 without wishing you had something a little better,” Hill said.

P-40 at Pearl Harbor

P-40s engaged Japanese aircraft at Pearl Harbor and in the Philippines in December 1941. They also served in North Africa in 1943 with the 99th Fighter Squadron, the first African American U.S. fighter unit.

Though often slower and less maneuverable than its adversaries, the P-40 Warhawk earned a reputation in battle for extreme ruggedness. It served throughout the war but was eclipsed by more capable aircraft.

More than 13,738 P-40 fighters were built from 1939-1944 at the Curtiss plant in Buffalo, Ny.

Just as automobile racing was gaining traction in the years before World War I (1914-18), so was airplane racing. The most famous of these aerial speed contests in the United States and Europe was the international competition known as the Schneider Cup Races.

According to an online report by the U.S. Naval Institute, Jacques Schneider, a wealthy French aero enthusiast, originated the races as a stimulus for seaplane design and the development of overwater flying. The competitions were administered by the Fédération Aéronautique Internationale and offered a trophy valued at some $5,000.

The races were for seaplanes and had to be flown entirely over water for a minimum distance of 150 nautical miles. Competitors raced against the clock — not each other — with the fastest average time winning. And the races had to be international.

The first Schneider race was held in 1913, with the United States represented by a privateer. The races were suspended during World War I, then resumed in 1919.

Subsequently, the U.S. military entered the Schneider races three times. The U.S. Navy-Curtiss racers twice won first and second places.

The Pulitzer Trophy Race 

In 1921, the Navy decided to compete in the Pulitzer Trophy Race, which the Army had won the previous year. Curtiss was the only major U.S. aircraft firm with prior experience in racer design, and on June 16, 1921, the Navy awarded the firm a contract for two aircraft, though some sources say three planes were built. The Navy had no effective designation scheme, so the aircraft were designated Curtiss Racer (CR) No. 1 and CR No. 2 (which was retained in naval service).

Designed by Mike Thurston and Henry Routh and built at Garden City, Long Island, New York, these were streamlined biplanes with a single, open cockpit. A variety of drag-reducing features were incorporated. Both CRs had wheeled undercarriages, but there were slight differences between the two aircraft.

Their 425-horsepower V-12 Curtiss engines ran on a 50/50 mixture of benzol and gasoline. The water-cooled D-12 had a displacement of 18.8 liters.

 Daring Lt. “Jimmy” Doolittle

According to a news story at Airminded.net, the first of the three Curtiss racers (including R3C) was put through its preliminary trials during the week of Sept. 19, 1922.

Alford J. Williams, U.S.M., was to pilot the Navy entry in the Pulitzer Race and Lieut. James H. Doolittle, Army Air Service, flew the plane for short trials to determine airworthiness.

On Sept. 18, Lt. Doolittle, for the first time, opened the throttle wide and flew the actual course of the Pulitzer Race from Mitchel Field, where these tests were carried out. W.L. Gilmore, chief engineer for the Curtiss Company, timed the trials and reported an average speed of 254 mph. for two circuits of the course.

The testing exceeded by approximately 11 mph the last Pulitzer speed figure set up when the Navy Curtiss racer won this race at St. Louis in 1923, clocking 243.6 mph.

The testing at Curtiss’ Garden City plant was considered in every way to be a great achievement in racing airplane design.

The Army went on to win the 1922 Pulitzer race with the new Curtiss R-6 racer, which led the Navy to order two similar aircraft in 1923. Designated R2C-1, these “logical” evolutions of the CRs and R-6s included improved engines that were boosted to 507 horsepower.

On Oct. 6 that year, Navy pilots captured first and second place in the Pulitzer race with speeds of 243.68 mph and 241.77 mph, respectively. Both speeds were later exceeded by those aircraft. In 1923, after the race, one of the R2C-1s was “sold” to the Army for $1 (becoming the Army’s R-8).

Curtiss Aeroplane Legacy

Curtiss produced several outstanding racing aircraft during the 1920s, flown by Navy and Army pilots, the latter including First Lt. “Jimmy” Doolittle.

According to Marine Lieutenant Colonel Robert Rankin of the naval institute:

“Although this country participated officially in the Schneider event for only three years, it did gain considerable technical data from the contests. In addition to the goodwill engendered by the Navy pilots, the races were of positive value in drawing the attention of the general public to our naval air program in the period following World War I when it was all too fashionable to criticize the services. More important, of course, were the research aspects of the contests, the results of which led to many important aircraft improvements and developments.”

The 1926 Curtiss-Bleecker Helicopter was an American prototype rotary wing aircraft that just didn’t fly, at least long enough for production

BY MARK MAYNARD

Looking like an escapee from a “Mad Max” movie, the Curtiss-Bleecker Helicopter was an American prototype rotary wing aircraft that was introduced in 1926, according to its page in Wikipedia.

Maitland B. Bleecker, a junior engineer from the National Advisory Committee for Aeronautics, designed the Curtiss-Bleecker Helicopter. Curtiss Wright constructed the two-seat aircraft for $250,000 over four years at it development facility in Garden City, Long Island, N.Y.

The aircraft featured a rotary wing design with a single engine. Each rotor, painted silver and yellow, had an individual propeller for thrust. Thrust was distributed from the centrally mounted engine through shafts to propellers mounted on each rotor blade.

A trailing control surface called a “stabovator” changes the pitch of the rotor. The aircraft was controlled by a stick that operated like a modern helicopter collective control. Yaw was controlled with a “Spin Vane” that used downwash from the rotor to pivot the aircraft with foot pedals.

The aircraft’s first flight was in 1926. However, testing on the Bleecker Helicopter was stopped after the failure of a drive shaft on a test flight in 1929. By 1933 the project was abandoned following vibrational issues in further tests.

The Garden City Curtiss-Wright plant closed in 1932 during the depression. Some machines were moved to Buffalo, N.Y. Others remained at Garden City and were sold off from time to time, up to 1935 or 1936, according to a legal case filed by Garden City.

Maitland Bleecker was 99 when he died on Oct. 19, 2002.
