Lloyd LS-x
The Lloyd LS-1 and LS-2 were the first self-developed aircraft of the Hungarian Lloyd Flugzeug- und Motorenfabrik . Only one copy was made at a time.
Lloyd LS-1
Using DFW steel hulls, the two designers Heinrich Bier and Tibor Melczer developed a new type of aircraft, the LS-1 (Lloyd Stahlrumpf-1) . It was powered by a 145 HP Hiero engine . A new engine cooling system with through-flow tubes was also used. This system was later known by the French as the Lamblin cooler .
The airfoil was a less curved Zsélyi airfoil.
After flying in, the aircraft was registered for the 3rd flight meeting in 1914 at Aspern airfield in Vienna . Three altitude world records were set:
- June 21, 1914 - 4120 m altitude with two passengers
- June 25, 1914 - 5600 m altitude with one passenger
- June 27, 1914 - with one passenger: The record of June 25 was improved to 6,170 m.
- June 28, 1914 - with two passengers: The record of June 21 was improved to 5440 m.
After the outbreak of the First World War , after broken wings on the Lohner Type B and Lohner Type C aircraft, the aircraft was approved and made it to the front together with the first Lloyd series aircraft . In István Dobos' book With the Airplane to the Front , two types of Lloyd aircraft are mentioned. The small Lloyd had a 120-horsepower engine from Austro-Daimler , while the great Lloyd , the LS-1, equipped with the Hiero engine with 145 horsepower.
During the course of the year, the LS-1 received several bullets in the wings during reconnaissance missions. It was returned to the factory in this condition and was exhibited at the 1917 aviation war exhibition in Budapest. The exhibition catalog mentions that Heinrich Bier set four altitude records in Aspern with this aircraft, two of which were still valid at the time.
The aircraft is exhibited in the Budapest Transport Museum. It is the first test aircraft from the Hungarian aircraft factory to bear the registration number 40.01 .
Lloyd LS-2
The Lloyd LS-2 was also a development of the Hungarian Lloyd aircraft and engine factory, which only existed as a prototype, but also flew combat missions in the First World War . It was also developed for beer and melczer.
Like the LS-1, it had a DFW steel hull. The two seat openings of the LS-1 were merged to form a cockpit; the hull was a little shorter. An Austro-Daimler with 165 hp was used as the engine . In contrast to the LS-1, it only had standard water cooling.
The aircraft suffered a broken landing gear while it was flying in . This could be repaired in the factory, after which the aircraft was immediately deployed to the front in Montenegro for Fliegerkompanie 6 of the Kuk aviation troops . One of the pilots was the experienced test pilot from OEFFAG Julius Arigi. The machine was probably lost in use.
