Flight Envelope (Standard Conditions)
< A graph showing Altitude in thousands of ft. on the vertical axis,
and Mach No. on the horizontal axis.
Vertical axis marked in 20,000 ft. increments starting at SL up to
100,000 ft. Horizontal axis marked in .5 Mach increments from 0
up to Mach 3.5.
Key numbers:
Minimum Airspeeds (Approx. Hope I read them right)
0 Mach to .5 Mach AND SL to 22,000 ft. = 145 KIAS
.5 Mach to Mach 1 AND 22,000 to 41,000 ft. = 350 KEAS
Mach 1 to Mach 3.2 AND 32,000 to 85,000 ft. = 310 KEAS
REDUCE KEAS TO 400 at M = 3.2
500 KEAS DESIGN LIMIT
<KEAS is Knots Equivalent Air Speed.
Any help explaining this would be appreciated.
Buck Adams told me it meant air speed over the wing.
So does this take into account being downstream of shocks
and air density, and out of BL. I thought dynamic pressure
was always what high Mach guys flew.
Buck also said something to the effect, you fly KEAS on
climb (sounds similar to how dynamic pressure is used on
high acceleration flights to high Mach) and Mach at cruise.
Or do I have that reversed. HELP!>

Payload Weight vs Time at Mach 3.2
< A graph showing Time At mach 3.2 (Minutes) on the vertical axis,
and Payload Weight - 1000 lbs, on the horizontal axis.
Vertical axis marked in 20 minute increments starting at 0 up to
80. Horizontal axis marked in 5000lb increments from 0
up to 25 (0 - to - 25,000 lbs).
The curve is very close to linear with a very gentle knee (reduction
in negative slope) at approx 12,000 lbs. So, lets call it linear.
It goes from a y-intercept of (0,80) to a (x,y) coordinate of
(25,24) (thats 25,000lbs,24minutes)
>
Pg. 21
Excess Thrust vs Altitude at Mach 3.2
< A graph showing Excess Thrust (LBS) on the vertical axis,
and Altitude (FT), on the horizontal axis.
Vertical axis marked in 2000 lb Thrust (Th) increments starting at 0 lb Th
up to 8000 lb Th. Horizontal axis marked in 5000 ft increments from 75,000 ft
up to 85,000 ft.
The curve has a gentle knee at (80,000 ft, ~5,000 lb Th). Other points
on the curve are ~ 7,500 lb of excess thrust at 75,000 ft
(75,000 ft, 7,500 lb Th), and ~ 3,000 lb excess thrust at 85,000 ft
(85,000 ft., 3,000 lb Th).
Ed. Note: As a class assignment, assume the relationship was perfectly linear,
compute the equation of the line and the value of the x-intercept
(altitude when excess thrust goes to 0). Or, assume linear to the
right of the knee of the curve.
Just for fun! Who knows if it's valid!

Payload Bay Capacities
<OK, here I really can't do it justice by words alone. There is a B+W line
drawing of all the bays running along the chine forward of the wing, on both
sides of the fuselage. There are a number of different size bays, including
inside the nose cone itself.
Personally, I think we have a hint here about how the RS-71
weapon storage bays may have been done. The interesting new issue is the
commonality between the YF-12A air-to-air missile technology that was
successfully demonstrated, and the possibility of using that technique on
a RS-71 where you replace the air-to-air missile with a air-to-ground
missile. I'm not saying that this was the plan but it is obviously suggested
by this foil and the next several foils! What do you all think?
There are some interesting YF-12A program results as well!>
<The bays are labeled on the left side, from the nose backward to the wing:
A-nose, K, M, P, S, and then on the right side from the nose back to the
wing: A-nose, D, L, N, Q, T. There is a centerline bay labeled C between
K & L>
Payload Vol (Cu ft) Typical payload Max Dims in Bay (inches)
Bay Each Bay Weight (Each Bay) - Typical Mounting
A (Nose) 23 550 lbs 30 X 30 X 75
C 7.2 150 lbs 24 X 24 X 16

Mach 2.2 to Mach 3.4.
The curve goes from left to right and is slightly concave down
but looks like it's composed of 3 segments.
Ordered pairs indicate:
(Freestream Mach No., Local Reynolds No.).
Points that make up the 3 segments are:
End points: (Mach 2.5, .91) and (Mach 3.2, 1.19).
Internal End Points Of Line Segs.: (Mach 2.7, 1.0) and (Mach 2.91, 1.09)>

Mach 2.2 to Mach 3.4.
The curve goes from left to right and is fairly linear.
