TABLE OF CONTENTS

NOTES:

1. THIS DRAWING CONTAINS DETAILS OF THE ORIGINAL PROPELLER AS DESIGNED BY

ROLLS ROYCE NAVAL MARINE, WALPOLE MA, AND PROPELLER MODIFICATIONS AS

DEVELOPED BY NSWC CODE 5800. SHEETS 3 THROUGH 5 ARE THE ORIGINAL

PROPELLER DESIGN FROM ROLLS ROYCE (DRAWINGS 100044043 AND 100044044B),

AND ARE PROVIDED FOR REFERENCE. THE PURPOSE OF THIS DRAWING IS FOR

MODIFICATION OF THE ORIGINAL PROPELLER TO MEET SHIP PERFORMANCE

REQUIREMENTS.

2. TEMPLATES ARE REQUIRED FOR EXECUTION OF THE PROPELLER TRAILING EDGE

MODIFICATION AS SHOWN IN DETAIL 10-8D.

3. AFTER MODIFICATION, THE PROPELLER SHALL BE STATICALLY BALANCED IN

ACCORDANCE WITH ISO 484/2 AND THE PROPELLER DRAWING. MATERIAL SHALL

BE REMOVED FROM THE SUCTION FACE OF THE BLADE SURFACES SPREAD OVER

AS LARGE AN AREA AS POSSIBLE. MATERIAL SHALL NOT BE REMOVED IN THE

FIRST OR LAST 10 PERCENT OF THE BLADE WIDTH OR THE 0.95R TO THE TIP. THE

BALANCE TOLERANCE SHALL BE 162 OZ-IN. AFTER PROPELLER BALANCE IS

ACHIEVED, SENSITIVITY OF THE BALANCE PROCESS SHALL BE VERIFIED BY

PLACING A WEIGHT EQUAL TO 4 OUNCES AT THE TIP OF A SINGLE BLADE AND

VISUALLY VERIFYING THAT THE WEIGHTED BLADE ROTATES TO THE BOTTOM. THE

SENSITIVITY CHECK SHALL BE PERFORMED ON EACH BLADE.

4. AFTER ANY REPAIR, THE PROPELLER SHALL BE BALANCED IN ACCORDANCE WITH

NOTE 3.

5. REPAIR TOLERANCES SHALL BE IN ACCORDANCE WITH NAVSEA S9245-AR-TSM-

010/PROP, CLASS II.

TRAILING EDGE GAGE NOTES

1. THE GAGE CONTOUR HAS BEEN DEVELOPED FROM THE BLADE SURFACE MODEL

BY INTERSECTING THE BLADE SURFACE WITH A PLANE WHICH PASSES THROUGH

THE 90% CHORD POINTS ON THE PRESSURE FACE AND SUCTION FACE AND THE

TRAILING EDGE POINT.

2. GAGES SHALL BE FLAT AND MANUFACTURED USING PLANER CUT DATA. DATA

VERIFICATION TABLES ARE IN TABLE 11-7H.

3. GAGES SHALL BE GALVANIZED SHEET METAL IN ACCORDANCE WITH ASTM A653,

CS TYPE B, 18 GAGE.

4. GAGES SHALL BE FOR THE PRESSURE FACE ONLY, 0.6R, 0.7R, 0.8R, 0.9R, 0.95R AND

0.975R.

5. THE FOLLOWING LINES AND IDENTIFYING CHARACTERS SHALL BE ENGRAVED

ON BOTH SIDES OF EACH TRAILING EDGE GAGE AS SHOWN IN DETAIL 10-8D:

(A) A REFERENCE LINE EXTENDING FROM THE TE TO THE CLOSED EDGE OF THE

GAGE AND LABELED "REF LINE".

(B) A LINE PERPENDICULAR TO THE REFERENCE LINE AT THE TRAILING EDGE

LABELED "TE".

(C) LINES PERPENDICULAR TO THE REFERENCE LINE MARKING THE LOCATION OF

THE 90 PERCENT AND 95 PERCENT OFFSET STATION ON THE PF.

(D) LETTERS " PF", IN THE LOWER CORNER TO INDICATE THE PRESSURE FACE

CONTOUR.

(F) GAGE IDENTIFICATION AS FOLLOWS: (ONE SIDE ONLY).

1. "NOAA CSV PROP DWG 245-8445988 REV _" (AS APPLICABLE).

2. "R/Ro___" (RADIUS AS APPLICABLE).

6. TRAILING EDGE GAGES SHALL BE APPLIED IN ACCORDANCE WITH NAVSEA S9245-

AR-TSM-010/PROP.
