Science and engineering}, month = {Nov}, note = {application/pdf, The authors have reported the field test results of a small propeller type of wind turbine in natural winds since 1978. It is confirmed from the results that the wind turbine power has increased proportionally to the third power of wind velocity, also as implied by the wind turbine theory, from the test results of data averaged in each 10 minute time range. In this paper, the test results are reported for 0.5 kW wind turbine made by Elektro-G. m. b. H. in Switzer-land, for natural winds in 1981 and '82. The observed data are consisted of two parts, one is the data of "short" periods for less than one hour, at sampling time intervals for less than one minute and the other the data of "long" periods for about one month, at sampling time intervals for one minute. The former are investi-gated and analysed for the power-correspondence of the wind turbine to the wind fluctuations in short periods and the latter for estimation of the turbine power characteristics in long periods.}, pages = {55--62}, title = {小型風車に関する実験的研究 第4報 ―自然風における小形水平軸風車の出力評価について―}, volume = {35}, year = {1985}, yomi = {オクダ, キョウカイ and ヤマギシ, ヒデアキ} }
