FUEL MANAGEMENT REVISION
NATURE OF PROPOSAL: This ECP covers the engineering design and fabrication of kits
riired to ..? .e the fuel tank sequencing of tanks #3 and #4 in A.12 aircraft(g)
125-132 13 and Also included are kits necessary to accomplidh the transfee
of fuel from to tank #6 and stop the transfer vthen 6800o pounds of fuel re.
main in tank #2 in aircraft 121, 122 and 125-132.
Partial kits vill be provided for the transfer of fuel from tank #2 to tank #6 for
aircraft 134 and 135. :Included in the kits will be:
Part Number Noun Ski
7-860-1 Shutoff Vag-- .
6-160-1 Pressure Refueling Valve . 2
7-160-1 , Pilot Valve 2
REASON FOR PROPOSAL: This ECP will result in tank #4 being the last tank in the fuel
sequencing. As a result, the C.G. of the article viii be moved further aft for a
greater portion of the cruise condition. Moving the C.G. aft reduces trim drag, and
results in greater range. .
?
Reason for Revision: To reflect that partial retrofit kits for the transfer of fuel
tank #2 to tank #6 in aircraft 134 and 133 will be provided and to reduce the proposed
TarrlIce accordingly. The valves procured for these aircraft will be shipped to
th or use as field spares.
This ECP was approved by Headquarters Message 2341, dated 10 February 1965.

COMPRESSOR INLET PRESSURE INDICATING SYSTEM
NATURE OF PROPOSAL: This system would enable the pilot to see the total inlet pressure
in ,each_compressor and the reouired total pressure on a triple indicator.? (See att-
ached pages 2 - 3 for technical description).
This BOP covers the following activities:
1. Design and development of the Pressure Indicating System.
2. Engineering design required to incorporate the System in A.I2 and YF-12A Air..-
craft.
3. Fabrication of retrofit kits for all A-12,Articles except- SiN 1211., andall YF-12A
aircraft.
'
The affect of this systed on the R-12 program will be covered on a separate 1IT-3664
ECP. (Continued on Page 2.)
REASON FOR PROPOSAL
1. Inlet pressure recovery can be directly checked during climb and cruise.
2. Will permit pilot to determine if inlet controls are functioning in a manner that
will allow completion of mission range.
3. This is only indication of inlet pressure recovery.
4. Present pressure recovery instrument now in use is simply made from a converted
dual reciprocating engine manifold gauge. It has been planned to replace this
with a true pressure recovery indicating system when sufficient flight test data
was available to make tbis possible. .
5. Pilot can read small aircraft yaw angles from differences in right and left inlets

NATURE OF PROPOSAL (Continued)--
The proposed system calculates and provides a visual display of the pressure defined
by the expression, P = Ve 2P400. Visual displays of actual left and right static
400
pressures are provided in such a manner as to permit comparison with the calculated
pressure.
The pressure display is obtained through the use of a triple pointer indicator. A
separate electronics package houses the associated amplifiers and bridge circuits.
Potentiometer type pressure transducers are employed to convert the left and right
static pressures into an electrical signal. Intelligence for use in the pressure
calculation is obtained by means of Characterized potentiometers located in and driven
by the Air Data Computer.
One of the potentiometers located in the ADC is characterized to produce an output
which is proportional to Ye 2. The second potentiometer is characterized to produce
400
an output which is proportional to 1 . These potentiometers, in conjunction with
Fr+134.
two (2) fixed resistors and two (2) trim potentiometers, constitute one half (i) of
a Wheatstone bridge. Trim pots and resistors in the electronics package and a re-
balance potentiometer in the indicator, make up the second half of the bridge. Bridge
Unbalance is amplified and a servo motor drives the indicator potentiometer wiper to
the position required to restore balance.
Indicator - The proposed triple pointer indicator contains three (3) motors, three
(3) gear trains, and three (3) rebalance potentiometers within a single square case.
The' indicator places the calculated pressure in the form of a bug type pointer which
provides visual representation of an allowable pressure band width.

Control Unit - This unit contains the three (3) bridge circuits and the three (3)
amplifiers required for the system.
Internally, this device consists of five (5) rectangular circuit boards which FLre
supported from the bac:I:plate by means of standoffs. :ix (6) potentiometers are lo-
cated under a cover on the backplate and are used for field adjustment of the system.
Two (2) multipin connectors are employed for making electrical connections.
The circuit used to calculate pressure is essentially a Wheatstone bridge. Ralf of
the bridge is located in the control unit and the other half is in the ADC.
Pressure Transducer - The proposed pressure transducers are of the bellow/potentio-
meter type. Provisions can be made to attach these units to the control unit or they
may be situated at some other convenient point. These devices will be in a location
which will minimize the required pressure line run.

TITLE OF PROPOSAL:
COMPRESSOR INLET PRESSURE INDICATING SYSTEM
NATURE OF PROPOSAL:
This system would enable the pilot to see the total inlet pressure in each compressor
and. the required total pressure on a triple indicator. (See attached pages 2 - fnr
technical description.)
This ECP covers the following activities:
1. Design and. development of the Pressure Indicating System.
2. Engineering design required to incorporate the System in all A-12 and AF-12 Aircra 1
3. Fabrication of retrofit kits for all A-12 and AF-12 Aircraft,
4. Installation on all A-12 and. AF-12 Aircraft.
The affect of this system on the R-12 program will be covered on a separate HT-3664 EC i
, (Continued- on Page 2)
REASON FOR PROPOSAL :
1. Inlet pressure recovery can be directly checked. during climb and cruise.
2. Will permit pilot to determine if inlet controls are functioning in a manner that
will allow completion of mission range.
3. This is only indication of inlet pressure recovery.
4. Present pressure recovery instrument now in use is simply made from a converted
dual reciprocating engine manifold gauge. It has been plaipaed to replace this
with a true pressure recovery indicating system when suff14ent flight test data
was available to make this possible.
5. Pilot can read small aircraft yaw angles from differences in right and left inlets.

NATURE OF PROPOSAL (Continued)--
The proposed system calculates and provides a visual display of the pressure defined
by the expression, P = Ve 2P400. Visual displays of actual left and right static
400
pressures are provided in such a manner as to permit comparison with the calculated
pressure.
The pressure display is obtained through the use of a triple pointer indicator. A'
separate electronics package houses the associated amplifiers and bridge circuits.
Potentiometer type pressure transducers are employed to convert the left and right
static pressures into an electrical signal. ,Intelligence for use in the pressure
calculation is obtained by means of Characterized potentiometers located in and driven
by the Air Data Computer.
One of the potentiometers located in the ADC is characterized to produce an output
2
which is proportional to Ve . The second potentiometer is characterized to produce
400
an output which is proportional to 1 . These potentiometers, in conjunction with
4FTO
two (2) fixed resistors and two (2) trim potentiometers, constitute one half (i) of
a Wheatstone bridge. Trim pots and resistors in the electronics package and a re-
balance potentiometer in the indicator, make up the second half of the bridge. Bridge
unbalance is amplified and a servo motor drives the indicator potentiometer wiper to
the position required to restore balance.
Indicator - The proposed triple pointer indicator contains three (3) motors, three
(3) gear trains, and three (3) rebalance potentiometers within a single square case.
The indicator places the calculated pressure in the form of a bug type pointer which
provides visual representation of an allowable pressure band width.

Control Unit - This unit contains the three (3) bridge circuits and the three (3)
amplifiers required for the system.
Internally, this device consists of five (5) rectangular circuit boards which are
supported from the backplate by means of standoffs. Six (6) potentiometers are lo-
cated under a cover on the backplate and are used for field adjustment of the system.
\
Two (2) multipin connectors are employed for making electrical connections.
The circuit used to calculate pressure is essentially a Wheatstone bridge. Half of
the bridge is located in the control unit and the other half is in the ADC.
Pressure Transducer - The proposed pressure transducers are of the bellowshotentio-
,
meter type., Provisions can be made to attach these units to the contra unit or they
may be situated at some other convenient point. These devices will be in a location
which will minimize the required pressure line run.

This ECP was Item 0 on our 30 April 1964 ECP listing. We are proceeding based upon
approval given in H's TWX 6882, dated 12 May 1964.

TITLE OF PROPOSAL :
PILOT VOICE RECORDER
NATURE OF PROPOSAL:
This ECP provides a destructible pilot voice recorder in all A-12 Aircraft (13 Ships).
The program includes the selection of the recorder, development of a destruct system,
modifications to the recorder to increase recording time to the level consistent with
minimum plaYback intelligibility of sound, and production of kits required to incor-
porate the recorder system on all A-12 aircraft.
. .
REASON FOR PROPOSAL: This program satisfies Headquarters revir6ment for a destructi-
ble scratch pad for pilots. The recorder selected as best applicable for tlis re- 1
quirement is a Dictet which is modified to slow down the speed and add a series of
Exothermus Tape for destruct capability. This recorder is outfitted with i mill tape
and provides approximately one hour plus of recording time. The recorder is energized
by an on-off switch and started by means of the pilot microphone button. The recor
time provided should be sufficient for all operational missions presently planned.
The destruct system is triggered by pilot ejection.
This ECP was approved per Headquarters Message 3690, dated 5 March 1965.
Reason for Revision: To submit Proposed Target Price. This price reflects increased
developmental costs.

1. Forwarded herewith are copies of six ECP's, each of
which is over land therefore requires your approval in
accordance with your letter of 24 November 1964. In addition I NRO
have attached a list of ECP's under ;hat I have approved 25X1
since receipt of your letter. In both cases, a short justification
explaining the reason for the ECP is included. More detailed
explanation may be found on the attached ECP's.
2. It is recommended that you approve the six above
I-land notify me so that the contractor may be advised.
3. The ECP's included in this document, plus those which
have been approved prior to your memorandum of 24 November 1964,
will provide for the so-called major modification program which we
have been studying recently, with the exception of the following:
a. The addition of extra fuel tanks which we are
recommending against.
b. The stiffening of the rudder post arms and the
modification of the air data computer to obtain
climb capability, and,

4. At this time it appears that the modifications enumerated
in,paragraph 3 above can be accomplished as service bulletins.
5. Although it appears that some savings could be obtained
by accomplishing some of these ECP's and service bulletins in one
modification program at Palmdale, I do not think the amount of
savings would justify the security risk and the longer-down time of
the aircraft which would result in going to Palmdale. I will have a
program plan for the A-12 for the remainder of FY 65 and 66 within
the next week which will demonstrate that we can accomplish our
objectives with the above ECP program and still be able to re-program
money from the airframe line item to the J-58 engine line item to
accomplish objectives in the engine ro rain.
