1905 Aircraft Interactive

This page shows a computer drawing of the Wright brothers’ 1905 aircraft. This machine was the third powered aircraft built by the brothers. In a larger sense, this aircraft was the first practical working airplane because, in its design, the brothers solved the pitching problem which had plagued the 1903 and 1904 aircraft. This aircraft was the culmination of their efforts beginning in 1900.

By the end of 1904, the brothers were making flights of several minutes from Huffman Field outside Dayton, Ohio. The 1904 aircraft was hard to control and fairly heavy for its small 18 horse power motor. The brothers decided to keep the same engine, but to re-design the airframe to eliminate the pitch problem present on both the 1903 and 1904 machines. The solution was rather simple. The brothers increased the size of the elevator and rudder and moved the elevator and rudder farther from the center of gravity. This increased the torque produced by the control surface and provided greater control for the aircraft. The overall length of the aircraft increased from 18 feet to 28 feet.

Fuel Tank

Here is a photo taken in 1905 of the aircraft at Huffman Field with the launching “derrick” visible at the far right.

Between the 1904 and 1905 aircraft, you will notice that the radiator and fuel tank were moved back to the front strut, as on the 1903 aircraft, and the size of the fuel tank was increased. The weight was also reduced by eliminating the 70 pounds of ballast. The 1905 aircraft weighed about 860 pounds with the pilot. The brothers added small semi-circular surfaces called “blinkers” between the elevators to improve the aircraft’s lateral stability. The brothers retained the catapult launching system first used in 1904.

Flight

The 1905 aircraft could be flown until the fuel tank was empty; staying in the air for more than a half hour, flying nearly 25 miles around Huffman’s farm, executing turns and figure 8’s, and flying more than 50 feet off the ground.

After six years of work, the brothers finally had a practical working airplane and began to market it to the War Department.

Replica

To celebrate the Centennial of Flight in 2003, several people around the country have built replicas of Wright aircraft. Mark Dusenberry, of Dennison, Ohio, has built and flies a full scale replica of the 1905 flyer.
