Mounchavo da Povoa. ~Private Aeroplanes.~ Total at end of ~1910~ 1 " ~1911~ 2 " ~1912~ 2 ~Private Aviators.~ De Castro, Sanchez De Silva, Gomez ~Military Aviation.~ In 1912 a military corps was formed. At the end of 1912 it possessed _Avro_ (1--50 h.p.), _Voisin_ (1--80 h.p.), and _M. Farman_ (1--80 h.p.) (since wrecked). 1 _Deperdussin_. ~Private Aviation.~ In 1911 the _Gouveia_ mono. was built, span 9 metres, but it failed to fly. Also the _Avante_ biplane, which also failed. First flight in Portugal by a Portuguese was De Castro in September, 1912, with an old _Bleriot_. ROUMANIAN. ~Army Aeroplanes.~ At end of March, 1913, there were several 80 h.p. _Bristol_ monos., 2 _Bleriots_, 1 _Nieuport_, 1 _Morane_, 2 _Vlaiclu_, and several _H. Farman_ biplanes. Government school is at Bucharest. ~AVIATORS.~ Military. Capsa, Lieut. Negrescu, Lieut. Protpopscu, Lieut. Vacas, Lieut. Poly Zorileann, Lieut. (Ae. F. 587) Private. Bibesco, Prince (Ae. C. F. 20) Oznoth VLAICLU Monoplane. Designed by Ouvret Vlaiclu. First shewn at the Vienna Exhibition, 1911. Modified; it flew very well indeed at Aspern, June, 1912. The 1912 model is of entirely novel type, a tail first monoplane with a propeller either end of the main planes, and a triangular tail aft. Principal details are:--~Length~, 34-2/3 feet (10.50 m.) ~Span~, 30 feet (9.15 m.) ~Height~, 12 feet (3.65 m.) Wing frame in three sections with gap between. ~Motor~, 50 h.p., Gnome chain driven. ~Fuselage~, old style; landing chassis on three wheels only, with a single ash skid in front. Covered in engine driving the 31 foot propeller shaft for the 2 propellers. Rear tail consists of 2 fixed planes, a triangular damping plane and a triangular keel plane. Forward, an elevator and two semi-circular rudders (double faced). From this combination remarkable results are achieved, and all gyrostatic effect from the propellers eliminated. _Control_, horizontal wheel on column. Elevator depressed or otherwise by action on column. Note.--At Vienna, 1912, this machine took first prize for the smallest circle and also for accurate bomb-dropping. The original machine was purchased by the Roumanian Army. RUSSIAN. ~General Note.~--In the number of military machines and general attention to aviation Russia is only second to France. There are no effective machines of Russian design, but the Aviataka, Dux & Lomatuk firms build at home under foreign license, and there is also the Kennedy school (Anglo-Russian). ~Aerial Societies:~--
