The Ellehammer Semi-biplane was a pioneering aircraft flown in Denmark in 1906. Jacob Ellehammer built the aircraft based on design of the previous year. Like that aircraft, it featured a large, triangular wing, with a motor (of Ellehammer's own design and construction) mounted beneath it. The pilot sat on a seat that was suspended like a pendulum, allowing him to shift his weight to control the aircraft, similar in concept (if not execution) to the control of a modern hang-glider. Unlike his monoplane, however, the semi-biplane's main wing formed a constant, unbroken span. Additionally, it was fitted with an upper wing of the same triangular shape, which connected to the main wing at its three corners and to an arch above the aircraft's centreline.

  • エレハマー半複葉機（Ellehammer Semi-biplane）はデンマークの航空のパイオニアである、ヤコブ・エレハマーが1906年に製作した航空機である。前年に製作した単葉機の設計と同じように、大きな3角形の主翼をもち、エレハマーが設計製作したエンジンが翼の下に取り付けられた。操縦士席はブランコのように吊るされていて、現代のハンググライダーのように、操縦士の体重移動で、操縦する構想であった。3角形の主翼に３つの頂点と全面のアーチに結合された上翼が追加された。 1906年の8月16日にLindholm島で、短距離のジャンプに成功した後、9月12日、滑走路の中央に建てたポールに繋留して、ポールの周りを約50cmの高度で42mの連続距離を飛行に成功した。 1966年にArvid Ligaard Sørensenが、シトロエン・2CVのエンジンをつけた復元機を製作し、デンマーク航空博物館に寄付した。復元機のテストでは動力のプロペラへの伝達が難しく、滑走はできたが離陸はできなかった。 (ja)

  • The Ellehammer Semi-biplane was a pioneering aircraft flown in Denmark in 1906. Jacob Ellehammer built the aircraft based on design of the previous year. Like that aircraft, it featured a large, triangular wing, with a motor (of Ellehammer's own design and construction) mounted beneath it. The pilot sat on a seat that was suspended like a pendulum, allowing him to shift his weight to control the aircraft, similar in concept (if not execution) to the control of a modern hang-glider. Unlike his monoplane, however, the semi-biplane's main wing formed a constant, unbroken span. Additionally, it was fitted with an upper wing of the same triangular shape, which connected to the main wing at its three corners and to an arch above the aircraft's centreline. In this aircraft, Ellehammer made a short hop on on 16 August, and a sustained flight on 12 September, covering 42 metres at an altitude of around 50 cm (140 ft at around 2 ft). This was not a free flight, however, as the aircraft was tethered to a pole at the center of the runway. A replica of the aircraft was constructed in 1966 by , powered by a Citroën 2CV engine and donated to the Danmarks Flymuseum. Tests with the replica showed difficulties in transmitting engine power to the propeller and while this aircraft could taxi, it proved impossible to coax from the ground. (en)
