RT Journal Article ID 0143afff41a132b2 A1 Scheglova, Valentina Michailovna T1 EXPERIMENTAL INVESTIGATION OF AERODYNAMIC LOADS IN THE TIP SECTIONS OF A RIGID BLADE OF AN INCLINED MODEL ROTOR JF TsAGI Science Journal JO TSAGI YR 2009 FD 2010-02-10 VO 40 IS 2 SP 217 OP 239 K1 rotor K1 pressure difference K1 slip angle AB This work investigates the character and the degree of influence of a slip in the tip sections of the blade on the basis of multiple pressure measuring points. The number of drain holes in each section increases along with the increase of the number of sections where the loads are measured. Measurement of the dynamic pressure in the tip part of the blade is accomplished. The results of the pressure measurements in the tip sections at relative radii varying from 0.8 to 0.99 are given. Special attention is paid to the pressure distribution in the area immediately adjacent to the blade tip and directly at the blade tip. The flow maps of the blade tips are considered in order to accumulate experimental information. The results are presented in terms of the figures of pressure change along the radius and the chord, and information about the loads acting on the blade tip of a given configuration is given. This information can be used for design and for the calculations of loads on the blades.
