-LIST OF SYMBOLS

The following symbols are for the ship scale, the corresponding small letters refer to the model scale.

Non-dimensional coefficients have the same main symbol for the model and the ship.

The suffices M and S are used throughout, for the

model and the ship respectively, where differences occur due

to the values of Reynolds' number and advance speed coefficient

not being equal at the same Froude number.

The suffices 0 and B refer to propeller and

propulsion test results in open water and behind the hull

respectively.

The units used are given throughout the report.

RESISTANCE AND PROPULSION TESTS ON A VICTORY SHIP MODEL

INTRODUCTION

An example of the current method of carrying out

and analysing resistance and propulsion tests _{on ship models} at the N.R.C. Ship Tank was considered necessary.

This has been written for all concerned with the Ship Tank facilities, and also for making comparisons with

procedures in other tanks. The use of the Victory Ship

Lines in all laboratories doing similar work will enable

comparisons of results to be made. PARTICULARS OF MODEL 126

The 1/30 scale model used for the tests was built

up with 1-3/4-in, white pine laminations glued together under

pressure. The model was finished by hand to templates supplied

for each section shown on the Body Plan, and then given two

coats of primer with a plastic paint tot) coat. _{In between} coats the model was rubbed down with wet abrasive paper.

A 0.040-in, trip wire was fitted around the hull at

1/20 LBp aft of the forward perpendicular.

Figures 1, 2, 3 and 4 show the Body Plan, Water Lines, Stern Details and Bonjean Curves, while in Figure 5

curves of section area, section length, waterline breadth, as percentages of the maxima, are given. _{Figures 6 and 12} contain all particulars of the model for the 24-ft. and 28-ft. conditions, respectively.

The lines of the Victory ship are scaled down from

the following drawings received: _{Body Plan, N.S.P. Dwg. No.} W.0.-12c-1, and Stern Frame, _{N.S.P. Dwg. No, W.0.-12e-20}

RESISTANCE TESTS

Resistance tests were carried out for the 24-ft, and the 28-ft. conditions over a speed range of 3.7 to

5.24 ft./sec. corresponding to 12 to 17 knots for the _ship. Results of the tank tests are given in Figures 8 and 14,

while the calculation of effective powers is shown in Figures 9 and 15. _{On these latter sheets, the total resistance}

coefficients C'Tm x Sv at corresponding Froude numbers Fv are computed for a 15-ft. model at 59°F.

2

For ship figures a roughness allowance of ACf = 0.0004 is added to Schoenherrls smooth frictiOn coefficients.

Effective power-speed curves for the two conditions

tested are given in Figure 23, while the tank resistance curves are shown in Figure 22. Curves of total resistance coefficients are given in Figure 24.

4. PARTICULARS OF PROPELLER NO. 17

The Form Plan, Figure 16, shows the particulars of the four-bladed, right-hand propeller model tested. These particulars were taken from the drawings, Form Plan, N.S.P.

Dwg. No. W.00-12c-3 and sections Dwg. No. 32979 provided by

the National Physical Laboratory, England. The cylindrical sections were drawn ten times model scale to obtain the off-sets parallel to the shaft of the face and back of the sections. The model propeller was cast of white alloy metal being finished

to 0.005 in. of the required offsets and polished to a mirror

finish.

50 PROPELLh.ii OPEN WATER TEST

The model propeller was installed on the shaft

extending in front of the "Open Water Test Boat', in order to advance in undisturbed water. The results are given in Fig-ures 17 and 19, and plotted as KT and Kq values in Figure 25. From the faired KT and KA, values the open water efficiency 7

and the coefficient KT/J2 are computed and plotted. As can '

be seen from Figure 25, two open water tests were conducted;

Test 545 with a large dynamometer with which the results at the higher speeds of advance (low thrust and torque) were

unreliable, and Test 570 using a small dynamometer for testing

at the higher speeds. In order that the two tests would over-lap, the rotational speed of the propeller in the latter case was reduced from the 918 of Test 545 to 649 revolutions per minute.

6. SELF-PROPULSION TEST

The self-propulsion test was conducted over a speed range corresponding to 12 to 17 knots for the ship in the deep condition only. The model was propelled without a tow rope force. (This method of carrying out the test and the corresponding method of analysis were suggested by Mr. S.T. Mathews of N.R.C.)

The results of the test are given in Figure 10 and plotted in Figure 26.

7. _{PROPULSION TEST ANALYSIS}

The calculations for the propulsion _{particulars of} the ship are given in Figure 110 _{These are based upon the}

assumption that for a given corresponding _{speed of hull, the}

following ratios are identical for model and ship:

In order to obtain the ship figures for shaft

(iii), we know that for a given corresponding_ hull speed KTBS = KTBM x RTS 2 j 2 RTM

by assumptions (i) and (ii)), the value of Js can be found.

Hence Ns,

from whichDBS can be computed.

PERFORMANCE ESTIMATION

/VOH

5

The results of the calculation of delivered _power,

revolutions per minute, and thrust for the ship _{are shown in}

Figure 28. This is the performance estimation for a ship

under ideal conditions, i.e., smooth water and _{no wind. The}

roughness of the ship hull is accounted for in the _roughness

allowance of 0.0004 on Schoenherrls frictional _{coefficients°} COMPARISON WITH TRIAL DATA

In Figure 28 three points of corrected voyage data taken from a paper read before the Institution of _Naval

Architects by G. Aertssen in 1953, are also given. These

points compare well with the performance _estimate.

For convenience, curves of ship and propeller

coefficients are given in Figure 29.
