Patent DE-1881-Moshaiski
Lilienthal Museum's archive record says (after translation via google translate):[1]
- Filed from St. Petersburg, Russia
- In the patent of November 3, 1881 an aircraft with all modules is presented. It was the first aviation patent of Russia. The rectangular wings had a flat profile at low elongation, nothing was available to maintain the transverse stability. The tail unit directly on the wing was detrimental to the longitudinal stability, 3 propellers. The patent was registered on 4.6. Submitted in 1880 before Moshaiski traveled to the US via Estonia. It was realized in its fundamentals in the engine flight apparatus.
- As a concept he had previously developed: 1. a boat for the drive and 2 people; 2. on the boat 2 rigid wings; 3. The tail must be able to control up and down, right and left; 4. a large screw diameter; 5. at the rear part 2 small propellers, intended to control to the right and left as to support the front; 6. a box with wheels under the boat, so that the apparatus has approximately an angle of 4 degrees to the horizon, so at start a favorable angle to quickly reach the starting speed; 7. For the attachment of wings and tail 2 masts are available; As propulsion for the propellers, he envisaged a steam engine based on the Braiton system. He calculated as weight at 30 hp per horsepower for 2 hours between 11 and 12 pounds of fuel and water.

- Research: Seifert
The reference to Braiton system probably refers to this steam engine design: Brayton cycle (on en.wp)
- Whether this patent was actually granted is not clear from these sources ; for now it's documented here as YES, granted.

(This man, Алекса́ндр Фёдорович Можа́йский, whose name is also transliterated as "Alexander Fedorovich Mozhaysky", 1825-1890, being earlier in the trajectory we are studying, had a career predating the existence of the Imperial Russian Air Force, as such, and was (ultimately) an admiral in the Imperial Russian Navy. His aero-innovation, not hugely successful, due largely to challenges related to lift, began in 1876 and focused on the heavier-than-air. See Alexander Fedorovich Mozhaysky on English Wikipedia. "Mozhaysky's monoplane" was truly based on "one plane", that is, one planar surface.)
