    Description / Table of Contents: Zusammenfassung In der Arbeit werden die Ergebnisse einer experimentellen Untersuchung bezüglich Effektivität und Wärmeübergangsverhalten der durch zwei versetzte Reihen zweifach schrägwinkelig angestellter Bohrungen bewirkten Filmkühlung mitgeteilt, wobei die Einflüsse von Lochabständen und Turbulenzgrad bei drei Einblasverhältnissen (0,5; 1,0 und 1,7) vorrangig interessierten. Es wurde versucht, die Ergebnisse für die Effektivität der Filmklung durch eine zweidimensionale Korrelationsgruppe darzustellen. Eine Erhöhung des Bohrungsabstandes quer zur Strömung verringert die Effektivität der Filmkühlung und erhöht die Stanton-Zahl. Erhöht man den Turbulenzgrad des Freistromes, so sinkt die lokale Effektivität der Filmkühlung drastisch, während die Stanton-Zahl ansteigt, insbesondere beim Einblasverhältnis 0,5.
    Notes: Abstract This paper describes the results of an experimental investigation into the film cooling effectiveness and the heat transfer characteristics of two staggered rows of compound angle holes. The effects of hole spacings and turbulence intensity on film cooling and heat transfer characteristic are investigated for three blowing rates; 0.5, 1.0 and 1.7. An attempt has been made to correlate the film cooling effectiveness results using a two dimensional correlation group. The increase of spanwise hole spacing results in a reduction in the film cooling effectiveness and an increase in the Stanton number. Increasing the freestream turbulence intensity has caused a significant reduction in the local film cooling effectiveness but increased the Stanton number, especially at blowing rate of 0.5.
