In dit rapport wordt de in augustus 1986 gehouden NPOC-SPOT enquête besproken. Deze enquête is gehouden in opdracht van de Beleidsconnnissie Remote Sensing (BCRS), naar aanleiding van de start van het Nationaal Remote Sensing Programma (NRSP). De enquête was bedoeld om inzicht te krijgen in de markt mogelijkheden voor EARTHNET en SPOT satelliet...

Nadat Dr. van Holten (destijds TH-Delft) in 1974 het tipvaan windturbine concept had geformuleerd, is hieraan vanaf 1977 door de TH-Delft onderzoek verricht in het kader van het NOW. In het kader van het integrale tipvaanontwikkelingsprogramma heeft het NLR hieraan ook meegewerkt van september 1983 tot januari 1985. De inspanning van het NLR was...

The commonly used blade-element theory predicts a zero yawing moment in the time-average sense. Small-scale wind-tunnel experiments at the Eindhoven University of Technology revealed stable yawing moments at almost all operating conditions with the rotor in an upwind position with respect to the tower. The present comment shows, that this...

The lecture gives a review of the aspects pertaining to wind energy conversion. It starts with a short survey of different wind turhine and wind concentrator concepts. Next the aerodynamic characteristics of wind turbines are discussed. The main part of the lecture consists of a survey of the choice of the various parameters, determining a WECS,...

A second series of tests has been performed on a two-bladed horizontal axis wind turbine in the lowspeed wind timnel LST 3x2 of NLR. The tests have been carried out at a Reynolds number of 3.5x10 , referred to the blade chord. The investigation included the effect of turbulence on the turbine performance, the determination of the wake blockage...
