National Aeronautics and Space Administration Scientific and Technical Information Branch SUMMARY An lnvestigation of hellcopter rotor noise at model scale has been conducted ln the Langley 4- by 7-Meter Tunnel. Two rotor systems were used in this program to examine the main-rotor-only noise characteristics in preparation for a complete maln rotor/tail rotor interaction study. Each rotor system had sev~ral tip configurations in order to select at least one appropriate configuratl0n to use for the maln and tail rotor tests. The rotor systems were tested at various operating conditions par- tlcularly designed to evaluate the acoustic characteristics of each rotor/tip config- uration. Both acoustlc and aerodynamic data were acquired during this test; however, only aerodynamic data are presented herein. The acoustic data have been reported elsewhere and properly referenced within.

INTRODUCTION An lnvestlgation of helicopter rotor noise at model scale has been conducted in the Langley 4- by 7-Meter Tunnel. ThlS test was part of an acoustic program designed to develop a data base for maln rotor/tall rotor interactl0n noise studles. The lnl- tial plans for the program were to conduct the complete main rotor/tail rotor (MR/TR) effort over a perlod of time that would require three tunn~l entries. Phase I , con- ducted ln the 4- by 7-Meter Tunnel, was a study of main-rotor-only nOlse character- istlcs. Two rotor configuratlons each havlng the capabllity for several interchange- able tips were used for this lnvestigation. Phase II, conducted at the United Technology Research Center (UTRC), was a study of tall-rotor-only nOlse character- lstics, with an emphasls on tall rotor/pylon/empennage installation effects. These first two phases were intended to deflne the maln-rotor-alone and tall-rotor-alone noise characteristics in preparation for Phase III of the program. phase III was designed to utillze the informatlon collected in Phases I and II to select an appro- prlate set of MR/TR configurations and to obtain an MR/TR acoustic data base. The purpose of this report is to provide a repository of the aerodynamic data collected durlng Phase I.

The rotor systems used in thlS lnvestigation (Phase I) were models of the U.S.

Army UH-60 and Sikorsky S-76 rotors with several tlP conflguratl0ns. References 1 and 2 present some detailed performance characteristics of the UH-60 and S-76 rotors, respectively, for most of the tip configuratl0ns tested.

The fuselage, approx~matply 0.9 model rotor dLameter in length, enclosed the basLc model hardware, transmission, and controls for the rotor system. Photographs of the model system in the tunnel test section are shown in fLgure 3. Models of the UH-60 and the S-76 rotors (0.17 scale and 0.21 scale, respectively) with several interchangeable tip designs each were mounted on a fully artLculated hub and used Ln thLs test. The dLmensLonal and design characteristics of these two rotor systems are prov~ded in figurp 4 and table I. The tip configurations tested are defined Ln figure 5 with additional details on the parabolic tLP for the UH-60 rotor provided Ln figure 6.

The rotor hub was fully articulated, with cycl~c and collective pitch of the blades controlled by a swash plate dr~ven by remotely controlled actuators. Blade flapping and lead-lag anglps were measured at the flappLng hinge offset. The rotors were drLven by two 90-hp electrLc motors through a sharpd transmission. The entire system - rotor, transmission, and motor - was mounted on a six-component strain-gauge balance to measure rotor forces and moments. The model was mounted on a specLal model st~ng (fig. 3) that perm~ts the angle of attack and angle of s~deslip to be var~ed over wide ranges while the model ~s maintained at a fixed pos~tion in the tunnel.

The Langley 4- by 7-Meter Tunnel may be operated w~th either an open- or closed- throat test section by raLsing or lowering the side walls and ceillng. For thls investlgatlon the tunnel was operated in the open-throat mode wlth a floor in place.

The rectangular jet entrance to the test chamber is 14.5 ft high and 21.75 ft wide.

ACOUStlC treatment was employed to reduce reflectlons and improve the acoustic char- acterlstlcs of the test chamber. Some of this treatment can be seen in flgure 3 on the test section floor and ln figure 3(b) on the test chamber wall.

TEST PROCEDURES AND CONDITIONS The two rotor blade configurat~ons had the capab~lity for t~p mod~fication.

Four tlPS were selected for the UH-60 and five tips selected for the S-76. (See fLg. 5.) Since the purpose of the wind-tunnel Lnvestigat~on was to obtaLn an acous- tlC data base, only lLmited aerodynamic performance data were collected. For each rotor configuratl0n, the orig~nal intent was to obtain the basic hover character~s tics, run through a detailed acoustlC test envelope, and then conduct a limited aero- dynamic performance test at low advance ratios for each rotor configuratLon. For some configurations, the tests were shortened primarily because a tip configuratl0n fa~led on the rotor blade. The shortened test matrix is reflected ~n the incomplete run schedule for the aerodynamic and acoustic tests.

The rotor conflgurat~ons were tested for hover at var~ous levels of rotor rota- tLonal speed ranging from 1180 to 1500 rpm. The acoustic data were acquired at two levels of cT/a (0.064 and 0.086) for a range of free-stream velocities from 50 to 90 knots, and a range of tip-path-plane angles of attack from -10° to 10°. The limited aerodynamic data were acquired for a range of advance rat~os (0.15 to 0.30) and a range of tip-path-plane angles of attack (_6° to 3°). The acoust~c data and the aerodynamlc data were acqulred by different technlques. To obtain the acoustic data the procedure was to select an appropriate cT/a, free-stream velocity, and then run through an angle-of-attack sweep at zero flapplng in order to bracket the blade-vortex interaction phenomena as viewed on-line. (See ref. 3.) To obtain the aerodynamic data the procedure was to select an appropriate advance ratio and angle of attack, and then run through a collect1ve (CT/cr) sweep at zero flapping in order to develop a performance map at each advance ratio and angle of attack. All these tests were conducted at a constant value of rotor rotational speed, except for a few limited cases where the rotor and free-stream velocity were operated at a slightly reduced value but with matched advance ratio, cT/cr, and angle of attack.

The data presented in this report have not been adjusted for force and moment contribu- tions due to aerodynamic forces acting on the model rotor hub. The data for free- stream veloclties other than zero have been corrected for Jet-boundary effects by us~ng the methods described ~n reference 5. The corrected tunnel free-stream dynamic pressure and flow direction are used to compute all velocity parameters and angles of attack.

Unfortunately, after the test program, an anomaly was detectpd in the rotor bal- ance data. After thorough evaluation, the axial-force component was found to be biased by as much as 120 Ib (0.0125 co/a). Th1S bias was caused by an 1ncrease 1n the temperature of the rotor balance located next to the electric dr1ve motors. Even though nO temperature measurements were obta1ned in the vicin1ty of the rotor bal- ance, the data indicated that as the motor warmed up during a run the heat trans- ferred to the rotor balance and caused the apparent increase in axial force. Usu- ally, all Langley balances are thermally compensated; however, for this test, the balance was a new design for the NASA designers and thus not properly compensated.

The problem has since been corrected; however, the anomaly was still present in the rotor drag component data. Only the rotor aX1al-force measurement was seriously contaminated in these data, and an attempt was made to account for the dr1ft in the axial-force data. Thermal effects typically cause sh1fts in both zero readings and sensitivities, however, only the zero sh1ft error can be addressed 1n this data set.

The most straight-forward method of data correction would have been to apply a cor- rection based on temperature; however, S1nce temperature at the balance was not mea- sured that was not possible. Correction based on the time of operation was applied 1nstead.

All the rotor axial-force data from the hover rUns were collected into one large data base. A second-order polynomial regression analysis was performed On these aX1al-force data as a function of t1me from the start of the motors. Because for a pure hover test the rotor aX1al force should be near zero, depending on the abi11ty of the pilot to maintain zero flapping, this curve should provide a correction equa- tion that can be app11ed to the rest of the data at free-stream velocities other than zero. Th1s correct1on was app11ed to the raw aX1al-force data, and then the full data base was recomputed. S1nce the corrections had to be made as a fUnction of time, there st1ll rema1ns some uncerta1nty in the accuracy of the axial-force data.

Upon reV1ew of all the hover data after correction 1t appears that the uncertainty can be as much as ±25 lb (approx1mately ±0.0025 co/a). For this reason, the data are be1ng presented in tabular form and no attempt has been made to compare the per- formance of the various tip configurations. Since there is no way to assure that the rotor axial-force data at free-stream veloc1t1es other than zero have been success- fully corrected, it is important that the reader be careful in 1nterpret1ng any results that depend On the rotor axial-force measurements.

16. Abstrac~ An investigation of helicopter rotor noise at model scale has been conducted in the Langley 4- by 7-Meter TunneL The program described in this report was the first of a planned three-phase project, whose purpose was to examine the characteristic noise mechanism involved in main rotor/tail rotor interaction noise. This first phase was conducted with a main rotor only in order to identify the characteristic noise generated by only the main rotor. This report defines the aerodynamic operating conditions of the rotor system during the test. The acoustic data are properly referenced.
