PSP Rotor Description
​
​
​
​
​
​
​
​
Blade Number..................................................... 4
Radius......................................................... 66.5 in
Solidity....…………...............................………. 0.1033
Reference Chord.........................................5.45 in
Tip Chord.................................................... 3.27 in
Tip Sweep................................... 30 deg at 95% R
Flap Hinge..................................................... 3.0 in
Rotor Speed...........................................1150 RPM
Tip Mach Number.......................................... 0.58
​
Conditions
Calculations should be performed for a tip Mach number of 0.58. To allow for direct comparison to experimental data and with other's results it is recommended that the investigators cover the range of collective angles from 6 to 14 degrees.

Surface Geometry
​​
Surface geometry of the PSP rotor blades are available on the FileShare page in several formats.
​
**** STRUCTURED GRID ***
​
File: blade_structured.plot3d
Format: unformatted, double precision, multi-grid, no iblank, plot3d
There are three overset surface grids:
(1) main blade grid
(2) root cap grid
(3) tip cap grid
The volume grid is also available upon request.
​
​
**** UNSTRUCTURED GRID ***
​
The unstructured surface grid is provided in three
formats:
​
(1) File: blade_unstructured.nas
Format: formatted (ASCII), NASTRAN
(2) File: blade_unstructured.r8.ugrid
Format: Unformatted, double precision,
UGRID
(3) File: blade_unstructured.fvuns
