PROBLEM TO BE SOLVED: To provide a method for inhibiting deposit formation in a jet fuel at temperatures above 150°C, whilst not substantially adversely affecting the water separability of the jet fuel. SOLUTION: The invention relates to the method for inhibiting deposit formation in the jet fuel at temperatures above 150°C whilst not substantially adversely affecting the water separability of the jet fuel, wherein the method includes the step of adding at least one copolymer, terpolymer or polymer of an ester of acrylic acid or methacrylic acid or a derivative thereof to the jet fuel; wherein the copolymer, terpolymer or polymer of the ester of acrylic acid or methacrylic acid or derivative thereof is copolymerized with a nitrogen-containing, amine-containing or amide-containing monomer; or the copolymer, terpolymer or polymer of the ester of acrylic acid or methacrylic acid or derivative thereof includes nitrogen-containing, amine-containing or amide-containing branches.

摘要:
キャパシタ燃料プローブ(100)は、プローブ軸(X)に沿って互いに重ね合わされた複数のキャパシタセグメント(1〜9)を備える。キャパシタセグメントは、少なくとも3つのセットに分配され、別々に各セット内で電気的に並列接続される。すべてのセットに対して実行される容量測定は、プローブ軸に平行な燃料の誘電体定数の可能な変動を考慮しながら燃料レベル(H)を決定することを可能にする。キャパシタセグメントの頂部高さ値h n は、2からNまでの任意のn値について、h n−1
n・(K min −1)/(K max −1)となるように選択され、Nはキャパシタセグメントの個数であり、nはキャパシタセグメントの重ね合わせ順序に従って変化し、K min およびK max はキャパシタ燃料プローブに対して規定されている燃料誘電体定数の最小値および最大値である。
摘要:
PROBLEM TO BE SOLVED: To provide a fuel feeding device for a pilotless helicopter allowing lengthening a flying distance and a flying time and returning always assuredly corresponding to a residual volume of fuel. SOLUTION: This device comprises a main pump P2 adapted to feed the fuel to an engine 1, a main tank 4 communicating with the engine via the main pump, a sub-pump P1 adapted to feed the fuel to the main tank, a sub-tank 5 communicating with the main tank via the sub-pump, a main residual volume sensor 6 adapted to detect the residual volume of the fuel in the main tank, a sub-residual volume sensor 7 adapted to detect the residual volume of the sub-tank, a control device 8 with which the main pump, the sub-pump, the main residual volume sensor and the sub-residual volume sensor are connected, and a communication instrument 9 connected with the control device on the helicopter, and the device comprises an operating device 19 for driving/ controlling the helicopter on the basis of information transmitted from the communication instrument 9 on the ground side.
