1.0 SUMMARY OF ACCOMPLISHMENTS

Hydraulic Research and Manufacturing Company was awardedcoutract No. NAS 8-30893 on June 3, 1974, to design, develop,

fabricate, test and deliver five load fixture assemblies for

laboratory system testing of the Five Space Shuttle Main Engine(SSME) Propellant Valve Actuators. In addition, HR & M Co.

agreed to deliver a preburner valve actuator (PVA) that wasreferred to in the contract as "an alignment fixture to permit

precise adjustment of the load simulator mechanical interface."

The five dynamic load simulators are designed to simulate theloads reflected into the SSME Hydraulic Actuators by the Chamber

Coolant Valve (CCV), the Fuel Preburner Oxidizer Valve (FPOV),the Oxidizer Preburner Oxidizer Valve (OPOV), the Main Oxidizer

Valve (MOV) and the Main Fuel Valve (MFV). And they are similar

to the actual load fixtures used for acceptance testing of theSSME Hydraulic Actuators.

Late in October, 1974, HR & M Co. completed mechanical

drawings of the Load Simulators and forwarded them to NASA-MSFC for design review and approval. Comments and design

approval were received from NASA-MSFC in the middle of

November, 1974 and the next four weeks saw design and fabri-cation proceeding at a pace consistent with the scheduleddelivery date of March 3, 1975.

However, in the middle of December, 1974, Hydraulic Research& Mfg. Co. suffered a labor dispute and all work was stopped

for the duration of the dispute. Supplemental agreement No. 2,executed March 3, 1975, extended the contract delivery date

to July 3, 1975.

After settlement of the labor dispute, HR & M Co. continuedfabrication of the five load simulators and an electronic load

system that, with inputs of valve differential pressure (LhP(t))

and valve inlet pressure (P(t)), supplied by NASA, wouldaccurately simulate the loads reflected into each SSME Hydraulic

Actuator by its respective valve.

During the period of June 9 through June 13, 1975, Mr. John

Glaznez of NASA witnessed acceptance tests of the five loadsimulators in the Engineer Development Lab at HR & M Co. and

conditionally accep_ J them on June 13, 1975, subject to an

2.0 DESIGN AND FUNCTIONAL DESCRIPTION

2.1 General

The design and function of the five load simulators is the sameas that of the SSlVE-I-L'kS Load Fixtures used for acceptancetesting of the SSME Hydraulic Actuators at HR & M Co. Acomplete functional and operational description of the LoadFixtures is presented in the operation manual (HR No. 79700012).

2.2 Mechanical

Each of the load fixtures simulates flow torque by applyinghydraulic pressure through a three-stage servovalve to apush-push piston-crankshaft assembly.

Reference Drawing No. T34000280-1-61 and T34000290-1-68.

2.3 Electronic s

The electroniccontrolcircuitsaredividedintotwo sections.

One, the servoamplifier which multiplies the flow torque command

from the NOVA 1210 computer with the AP(t ) valve from NASA andsums this valve with crankshaft linkage multiplied by feedback _P.

Two, the friction scaling amplifier solves the friction equation

and sums that value with the P(t) and _P(t) values supplied byNASA.

The servoamplifierand frictionscalingamplifiersignalsaresummed togetherto applythe properdrivesignaltothe servovalve.

4.1 Load Fixture Control Transformt

The control transform uses known parameter_ to determine the

servovalve pressure drop corresponding to the required torque.The control transform is used (via computer) to set this servo-

valve pressure drop during actuator testing. The load fixtureprovides a shaft torque for a specific shaft angle. A schematicof the load fixture showing pertinent geometric parameters is

" shown in Figure 1.

Three equations which, when combines, will yield shaft torqueare:

1) T = P1LIA1 -P2L2A2 = (P1L1 -P2L2)A

For computer use it is advantageous for the curve s; own in

Figure 3 to be an equation. A program was written which

utilizes software provided by the time-share vendor (GeneralElectric Information Services) to generate the constant coefficients

of the polynomial.* The program generates the constant co-

The frictio_ torque (ln-lb) was detel_tned by the following

equations:

Chamber Coolant Valve (CCV)

f(t) = 35.6+ .01 AP(t )+ .047 P(t)

Fuel Preburner Oxidizer Valve (FPOV)

f(t) = 42.5 + .01 L_P(t ) + .047 P(t)

Oxidizer Preburner Oxidizer Valve (0POV)

f(t) = 42.5 + .01 AP(t ) + .047 P(t)

Main Oxidizer Valve (MOV)

f(t) = 111.4 + .01 L_P(t) + .047 P(t)

Main Fuel Valve (MFV)

f(t) " 111.4+ .01_P(t) + .047 P(t)

Where _P(t) (lb/tn2) is the pressure differential across theengine valve and P(t) (lb/ln 2) is the hydraulic pressure __t theinlet to the valve.

5.0 STATEMENT OF CONFORMANCE

The acceptance tests performed at HR & M Co. June 9 throughJune 13, 1975 and witnessed oy Mr. John Glazner of NASA-MSFCsatisfactorily determined that the Dynamic Load Simulators/LoadControl System has the capability to verify the propellant controlsystem performance. Further, :he SSME-HAS simulators willverify minimum and maximum engine thrust level loads at: well asengine start, stop and emergency shutdown transients leads.See Attachment II.
