The Sablatnig NI ( Sab NI for short ) was a German night bomber of the First World War , of which only a few copies were made, but from which one of the first passenger aircraft was developed after the end of the war .
development
In 1917, Idflieg commissioned Sablatnig Flugzeugbau GmbH to develop a night bomber. Josef Sablatnig and his technical director Hans Seehase based their design on the recently created reconnaissance aircraft C I , of which two prototypes had just been completed at the time. For this purpose, the C I with the serial number 7700/17 was tested for possible suitability for this purpose upon acceptance. After minor objections, Idflieg gave its approval and in August 1917 placed an order for 50 aircraft with the stipulation that the Bz IV engine from Benz, which was classified as more reliable , be installed instead of the Argus engine . As a result, the actual N I was created with this drive and the number 7730/17, which was given the designation N I Bz . Compared to the aircraft with the Argus engine, the payload increased from 597.34 kg to 680 kg and the take-off weight from 1568 kg to 1860 kg due to the other engine, although the Bz IV was 40 kg heavier. Series production started in 1918 and by the time of the armistice , around 30 aircraft are said to have been delivered to the air force, according to evidence to the Aviation Department (A) 281 stationed in Alsace .
Due to the foreseeable end of the war, planning began on October 31, 1918 under the direction of Seehase to convert the NI into a civilian model for passenger transport, and from November 15, after the drawings were handed over to the test department, construction of the prototype began using parts of the now abandoned building Bomber production. In addition, the aircraft received a closed cabin for two passengers installed in front of the pilot's cabin, otherwise its dimensions were identical to the N I Bz. Existing bomber planes were then equipped with a cabin, so that in 1919 a total of six N I were registered with the registration number D–84to D–89. After June 1920 this number grew by a further seven aircraft, so that a total of 13 civilian N I were used by Lloyd-Luftverkehr Sablatnig in civil air traffic in the post-war period. However, some of them had to be scrapped at the instigation of the ILÜK , so that on June 23, 1921, according to official information, there were only five copies in the Lloyd's inventory. In 1919 Sablatnig developed the PI passenger aircraft based on the N I with a cabin for four people.
