Information, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Boeing B-29 Superfortress &quotEnola Gay&quot:

Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Globe War II and the 1st bomber to property its crew in pressurized compartments. Although created to fight in the European theater, the B-29 discovered its niche on the other side of the globe. In the Pacific, B-29s delivered a assortment of aerial weapons: conventional bombs, incendiary bombs, mines, and two nuclear weapons.

On August six, 1945, this Martin-constructed B-29-45-MO dropped the 1st atomic weapon employed in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance climate reconnaissance aircraft that day. A third B-29, The Excellent Artiste, flew as an observation aircraft on both missions.

Quoting Smithsonian National Air and Space Museum | Grumman F6F-3 Hellcat:

The Grumman F6F Hellcat was originally conceived as an sophisticated version of the U.S. Navy’s then present front-line fighter, the F4F Wildcat (see NASM collection). The Wildcat’s intended replacement, the Vought F4U Corsair (see NASM collection), 1st flown in 1940, was displaying excellent guarantee, but improvement was slowed by problems, including the crash of the prototype.

The National Air and Space Museum’s F6F-three Hellcat, BuNo. 41834, was constructed at Grumman’s Bethpage, New York, factory in February 1944 below contract NOA-(S)846. It was delivered to the Navy on February 7, and arrived in San Diego, California, on the 18th. It was assigned to Fighter Squadron 15 (VF-15) on USS Hornet (CV12) bound for Hawaii. On arrival, it was assigned to VF-three where it sustained harm in a wheels-up landing at NAS Barbers Point, Hawaii. After repair, it was assigned to VF-83 exactly where it was utilized in a instruction role till February 21, 1945. Soon after many transfers 41834 was converted to an F6F-3K target drone with the installation of sophisticated radio-manage equipment. It was painted red with a pink tail that carried the quantity 14. Its mission was to be used in Operation Crossroads – the atomic bomb tests at Bikini Atoll. It flew on June 24, 1946, with a pilot, on a practice flight and was launched, unmanned, quickly following the 1st bomb test. Instrumentation on board and photographic plates taped to the manage stick obtained data on radioactivity. Three far more manned flights preceded the final unmanned flight on July 25, 1946, which evaluated the very first underwater explosion. Records indicate that exposure of this aircraft to the radioactive cloud was minimal and residual radiation is negligible.

F6F-3K 41834 was transferred to NAS Norfolk and logged its final flight on March 25, 1947, with a total of 430.2 flying hours. It was assigned to the National Air Museum on November three, 1948, and remained at Norfolk till October four, 1960, when it was moved by barge to Washington and placed in storage. In 1976 this Hellcat was loaned to the USS Yorktown Museum at Charleston, South Carolina. A superficial restoration was performed at the museum, but since of the harsh environment and its poor condition the Hellcat was returned to NASM on March 16, 1982. In 1983, it was sent to Grumman Aerospace exactly where a team of volunteers entirely restored the aircraft. In 1985, it was shipped back to the Paul E. Garber Preservation, Restoration and Storage Facility in Suitland, Maryland, and put in storage. NASM’s F6F-3 Hellcat is scheduled to be displayed in the new Steven F. Udvar-Hazy center at Dulles International Airport in Virginia in 2004.

Information, quoting from Smithsonian National Air and Space Museum: Steven F. Udvar-Hazy | Northrop N1M:

John K. &quotJack&quot Northrop’s dream of a flying wing became a reality on July 3, 1940, when his N-1M (Northrop Model 1 Mockup) very first flew. 1 of the world’s preeminent aircraft designers and creator of the Lockheed Vega and Northrop Alpha, Northrop had experimented with flying wings for over a decade, believing they would have significantly less drag and greater efficiency than traditional designs. His 1929 flying wing, even though effective, had twin tail booms and a standard tail. In the N-1M he produced a correct flying wing.

Constructed of plywood about a tubular steel frame, the N-1M was powered by two 65-horsepower Lycoming engines, later replaced with two 120-horsepower Franklins. Whilst its flying traits have been marginal, the N-1M led to other designs, which includes the Northrop XB-35 and YB-49 strategic bombers and ultimately the B-2 stealth bomber.

Long Description:
The N-1M (Northrop Model 1 Mockup) Flying Wing was a natural outgrowth of John K. &quotJack&quot Northrop’s lifelong concern for an aerodynamically clean design and style in which all unnecessary drag caused by protruding engine nacelles, fuselage, and vertical and horizontal tail surfaces would be eliminated. Created in 1939 and 1940, the N-1lM was the 1st pure all-wing airplane to be developed in the United States. Its design and style was the forerunner of the larger all-wing XB-35 and YB-49 bomber! reconnaissance prototypes that Northrop hoped would win Air Force production contracts and ultimately adjust the shape of modern day aircraft.

Right after serving apprenticeships with the Lockheed brothers and Donald Douglas in the early 1920s and designing the highly profitable and innovative Lockheed Vega in 1927, Northrop in the late 192Os turned his focus to all-wing aircraft. In 1928, he left the employ of Lockheed and organized the Avion Corporation a year later he produced his very first flying wing, which incorporated such revolutionary functions as all-metal, multicellular wing and stressed-skin building. Despite the fact that the 1929 flying wing was not a correct all-wing design simply because it produced use of external manage surfaces and outrigger tail booms, it paved the way for the later N-1 M, which proved the fundamental soundness of Northrop’s idea for an all-wing aircraft. At the time, nonetheless, Northrop did not have the income to continue creating the all-wing concept.

In 1939, Northrop formed his personal aircraft firm, Northrop Aircraft, Inc., and as a result was in a position to finance study and development of the N-1M. For assistance in designing the aircraft, Northrop enlisted the not aerodynamicist Dr. Theodore von Karman, who was at the time Director of the Guggenheim Aeronautical Laboratory at the California Institute Technology, and von Karman’s assistant, Dr. William R. Sears. Walter J. Cerny, Northrop’s assistant design and style chief, became the overall supervisor for the project. To figure out the flight characteristics of an all-wing design and style, Northrop Cerny performed in depth wind tunnel tests or flying wing models. Eventually, the style of the N-1 M benefited from the new low-drag, boost stability NACA airfoils as properly as improved flaps spoilers, and other aerodynamic devices.

Right after a period of a year, the N-1M, nicknamed the &quotJeep,&quot emerged in July 1940 as a boomerang-shaped flying scale mockup constructed 01 wood and tubular steel with a wingspan of 38 feet a length of 17 feet, and a height of five feet. Pitch and roll handle was accomplished by indicates of elevons on the trailing edge of the wing, which served the function of both elevator and aileron the spot of the standard rudder was a split flap device on the wing guidelines these had been originally drooped downward for what was believed to be much better directional stability but later straightened.

Controlled by rudder pedals, the split flaps, or &quotclamshells,&quot could be opened to increase the angle of glide or lessen airspeed and hence act as air brakes. The center of gravity, wing sweep, arrangement of handle surfaces, and dihedral had been adjustable on the ground. To lower drag, the aircraft’s two 65-hp Lycoming -145 four-cylinder engines had been buried within the fuselage. These were later found to be lacking in sufficient energy to sustain lift and had been replaced by two 120-hp six-cylinder 6AC264F2 air-cooled Franklin engines.

The N-1M produced its very first test flight on July 3, 1940, at Baker Dry Lake, California, with Vance Breese at the controls. Breese’s inaugural flight in the N-1 M was inauspicious. In the course of a high-speed taxi run, the aircraft hit a rough spot in the dry lake bed, bounced into the air and accidentally became airborne for a handful of hundred yards. In the initial stages of flight testing, Breese reported that the aircraft could fly no greater than five feet off the ground and that flight could only be sustained by sustaining a precise angle of attack. Von Karman was referred to as in and he solved the dilemma by creating adjustments to the trailing edges of the elevons.

When Vance Breese left the N-1 M plan to test-fly the North American B-25, Moye Stephens, the Northrop firm secretary, took more than testing of the aircraft. By November 1941, right after possessing created some 28 flights, Stephens reported that when attempting to move the N-1M about its vertical axis, the aircraft had a tendency to oscillate in what is referred to as a Dutch roll. That is, the aircraft’s wings alternately rose and fell tracing a circular path in a plane that lies amongst the horizontal and the vertical. Despite the fact that Stephens was fearful that the oscillations may possibly not be controllable, he identified that adjustments to the aircraft’s configuration cleared up the issue. In Might 1942, Stephens was replaced by John Myers, who served as test pilot on the project for approximately six months.

Even though the precise period of flight testing for the N-1M is challenging to decide simply because both Northrop and Army Air Forces records have been lost, we do know that following its initial test flight at Baker Dry Lake, the aircraft was flown at Muroc and Rosamond Dry Lake, and at Hawthorne, California, and that late in the testing program (most likely after January 1943) it was towed by a C-47 from Muroc to Hawthorne on its last flight with Myers as the pilot.

From its inception, the N-1M was plagued by poor functionality because it was each overweight and chronically underpowered. Regardless of these troubles, Northrop convinced Common H. H. Hap&quot Arnold that the N-1 M was profitable enough to serve as the forerunner of far more sophisticated flying wing ideas, and the aircraft did type the basis for Northrop’s subsequent improvement of the N-M9 and of the bigger and longer-ranged XB-35 and YB-49 flying wings.

In 1945, Northrop turned the N-1M over to the Army Air Forces in the hope that it would someday be placed on exhibit. On July 12, 1946, the aircraft was delivered to Freeman Field, Indiana. A small more than a month later, the N-1M was offered to the National Air Museum and placed in storage at Park Ridge, Illinois. On Could 1,1949, the aircraft was placed in the Museum’s collection, and a couple of years later moved in packing crates to the Museum’s Preservation, Restoration and Storage Facility in Suitland, Maryland. In 1979, the restoration of the N-1M began, and by early 1983, some 4 decades after it had produced its final flight, the aircraft had been returned to its original condition.

Quoting Smithsonian National Air and Space Museum | Northrop P-61C Black Widow:

The P-61 Black Widow was the 1st U.S. aircraft developed to find and destroy enemy aircraft at night and in undesirable climate, a feat created feasible by the use of on-board radar. The prototype first flew in 1942. P-61 combat operations began just right after D-Day, June 6, 1944, when Black Widows flew deep into German airspace, bombing and strafing trains and road site visitors. Operations in the Pacific started at about the exact same time. By the finish of Globe War II, Black Widows had seen combat in each theater and had destroyed 127 enemy aircraft and 18 German V-1 buzz bombs.

The Museum’s Black Widow, a P-61C-1-NO, was delivered to the Army Air Forces in July 1945. It participated in cold-weather tests, high-altitude drop tests, and in the National Thunderstorm Project, for which the top turret was removed to make room for thunderstorm monitoring equipment.
