Variants Anatra Anadis

The Anatra DS or Anasal was a two-seat reconnaissance aircraft developed from the Anatra D (Anade). It was built in Anatra factory in Odessa in Russian Empire and flown during World War I and by both sides during the Russian Civil War.

A main difference from a previous model was replacing primitive 100 hp rotary engine with much more powerful 150 hp radial engine Salmson, what improved performance. The engine was unique, being one of few water-cooled radial engines, hence the plane had a water radiator before an upper wing. It was license-built in Russia. Forward fuselage part was similar to the predecessor, with partial engine cover, open at a bottom, with characteristic holes. The plane was also slightly bigger and more heavily armed, adding a synchronised forward-firing machine gun for the pilot in addition to the observer's weapon.

The plane, named Anasal (short of Anatra Salmson) was first flown on 7 August 1916 (25 July 1916 old style). After long trials, a production started only in summer 1917, and before a Soviet revolution in November 1917 some 60-70 were manufactured, many other were in different stages of completion. It should be noted, that many aircraft differed in details from each other.

In March 1918 Odessa was taken by Austro-Hungarian forces, and in May Austrian government ordered 200 Anasals, as Anatra C.I, for training and observation. 114 were received by the Austrians by September 1918, some half was given to training units before the end of World War I.

Major post-war user of Anasal was Czechoslovakia, with 23 aircraft, used in military, thereafter civilian aviation. One of them survived in Praha-Kbely museum. Eight Anasals were used by revolutionary forces in Hungary.
