<p><img border="0" src="images/cover.jpg" width="500" height="616"></p>
<p><font face="Arial" size="2">A technological tour de force of epic proportions, the legend of the XB-70 Valkyrie very nearly surpasses the performance of this extraordinary aircraft. Built in the 1960s as a result of a USAF proposal for a supersonic bomber with high subsonic cruising speed and supersonic dash capabilities, the massive XB-70 was to have carried the same bombload as the B-52 Stratofortress at a higher supersonic speed than the Air Force's current strategic bomber, the B-58 Hustler. A later requirement specified that the plane be able to fly the entire mission at Mach 3.0 or greater, with a range of up to 10,500 miles and a maximum gross weight of 490,000 pounds. In the event, technology quickly relegated the Valkyrie to the role of supersonic research testbed and flagship of the USAF's public relations fleet. Ground-to-air missiles and advanced radar made the XB-70's supersonic mission impossible. The bomb bay of the aircraft was instead packed with data acquisition equipment, and the information gathered helped propel the United States Air Force even further into the supersonic jet age, with the information going to help develop future generations of supersonic interceptors.</font></p>
<p><font face="Arial" size="2"><b><i>Flight Characteristics and Flight Modeling</i></b></font></p>
<p><font face="Arial" size="2">The AlphaSim XB-70 Valkyrie was created using the
original XB-70A Flight Manual, the cover of which is reproduced above. The
Valkyrie is a "flagship" quality aircraft in the AlphaSim line and
extreme care was taken to replicate as closely as possible the features and
characteristics of this unusual and iconic aircraft.</font></p>
<p><font face="Arial" size="2">AlphaSim aircraft are primarily designed for
people who like to spend their time flying rather than following lengthy and
complicated procedures, so many of the design features of this plane are
automated, such as the fuel management. This reflects the design
philosophy of the real plane, where as many of the complex systems as possible
were given over to fully automatic control. We urge anyone truly
interested in the history and flight characteristics of this amazing aircraft to
purchase the actual XB-70A Flight Manual. Our aircraft can be operated
according to the actual procedures and will match the published specifications
with a very high degree of accuracy.</font></p>
<p><font face="Arial" size="2">The Valkyrie is an advanced delta wing
design. The delta wing does not stall as a conventional wing does.
There is no well-defined stall; the aircraft will begin to mush and pitch up
once a critical angle of attack is exceeded. For this airplane, do not
exceed 17 degrees angle of attack. If this is exceeded the nose will
continue to pitch up and it may take full forward stick to recover. The
canard provides a good measure of control at high alpha, unlike other delta wing
designs, and the canard can be seen now on all modern delta wing aircraft, such
as the Gripen and Eurofighter Typhoon.</font></p>
<p><font face="Arial" size="2">The aircraft is quite stable and the controls are
very well harmonized, and it is surprisingly responsive for an aircraft of its
size. However, the airframe is not up to high G maneuvers. In fact,
negative Gs are prohibited as are all acrobatics and sudden maneuvers.
Please review the aircraft limitations for specific information.</font></p>
<p><font face="Arial" size="2"><b><i>Fuel Supply</i></b></font></p>
<p><font face="Arial" size="2">The XB-70 had fuel tanks crammed into every nook
and cranny of the wings and fuselage. All the tanks were interconnected
through a complex system of transfer lines and pumps which allowed for
completely automatic fuel and weight management. However, the actual
amount of fuel the plane could carry varied with the specific mission
configuration, and each of the two aircraft produced had a different fuel
capacity. A normal takeoff fuel load was about 135,000 lbs of fuel, but
the plane could carry much more. This flight model has been set up to
carry a maximum of 240,000 pounds of fuel, enough to allow it to meet the
published range specifications. This results in a takeoff weight of just
over 470,000 lbs.</font></p>
<p><font face="Arial" size="2"><b><i>Engine Management</i></b></font></p>
<p><font face="Arial" size="2">Flight Simulator does not allow for more than
four engines. The engines are arranged in the flight model as follows: (1,
1), 2, 3, (4, 4). That is, the outer pairs of gages show information for Engines 1 and
4, while the inboard gages show information for Engine 2 and 3. The thrust has been adjusted so that the four
engines in this flight model produce the same power as the six engines n the
real aircraft. That is, each engine in the flight model makes 150 percent
of the rated power, which is the same as if we could have six at the normal
power rating. Thus, there is no compromise in performance. Unless
you are operating with one or more engines out, this arrangement will be
transparent; you'll perceive there are six operational engines, and each of the
six "virtual" engines has its own dedicated instruments.</font></p>

<p><b><font face="Arial" size="2">Wing Fold Function</font></b></p>
<p><font face="Arial" size="2">The variable-fold wings are manually adjusted
and need to be set into the correct position by the pilot, depending on the
aircraft's indicated airspeed or Mach number. Use the switch on the main
2D panel to position the wing tips, or use the "flaps" key to set this
position.</font></p>
<p><font face="Arial" size="2"><b>Nose Ramp</b></font></p>
<p><font face="Arial" size="2">The nose ramp reduced drag in the real aircraft
but has only a cosmetic function in this model. It can be raised using the
button on the main 2D panel or by using the tailhook up/down command.</font></p>
<p><font face="Arial" size="2"><b>Canard Flap</b></font></p>
<p><font face="Arial" size="2">The canard flap extends to a single position on
the "spoilers" key or using the canard flap switch on the main panel.</font></p>
<p><b><font face="Arial" size="2">Power Schedule</font></b></p>
<p><font face="Arial" size="2">There are three ways to set the power in this
flight model:</font></p>
<ul>
<li><font face="Arial" size="2">Reading the mouse tooltip when positioned over
the ECU (throttles) popup</font></li>
<li><font face="Arial" size="2">Noting the index mark on the ECU on the popup</font></li>
<li><font face="Arial" size="2">Reading percent of engine RPM on the gages
(tooltip is very accurate)</font></li>
</ul>
<p><font face="Arial" size="2">Your joystick throttle slider will provide an accurate and realistic way to set power
in the XB-70 Valkyrie. The range from 0-35% of the throttle joystick position
(read this value using the mouse tooltip) will provide power from IDLE to full military (MIL)
power. At exactly 35% throttle joystick position, 100 percent RPM will be
obtained which equals MIL power. Above 35% throttle and 100 % RPM is
the afterburning range, which is the most important range for a supersonic
aircraft. A full 65% of the range of the throttle control is available to
set exactly the right amount of afterburner power and this can be very finely
adjusted. This takes the engine into the "overspeed" range from
100-106% RPM. While it may seem that there is only a small range of
engine RPM to work with, keep in mind that engine RPM remains more or less
constant within a narrow band whilst the afterburners are on. The actual
thrust is determined by the amount of fuel being sprayed into the burner cans,
not from the engine RPM. However, higher engine RPM does correspond to
higher thrust. Engine RPM can be read to 0.01 of a percent, and is easily
set and easily repeatable.</font></p>
<p><font face="Arial" size="2">Use the alternate view of the throttles by
cycling through the virtual cockpit views, or use the popup ECU panel to view
and set throttle position and power. The tooltip in percent does not
correlate exactly to the ECU throttle index markings, but can be noted and recorded to help
set power. See the images below for details, noting the relationship
between the mouse tooltip reading and the index marks on the ECU.</font></p>

</ol>
<p><b><font face="Arial" size="2">Tactical Climb and Transonic Flight - Level
Flight Technique</font></b></p>
<p><font face="Arial" size="2">The XB-70 is a powerful aircraft. It is very
easy to overspeed, so keep your throttles under control at all times.
Throttle back to minimum afterburner after reaching 300 knots IAS on
climbout after gear is retracted. Accelerate to 450 knots IAS,
adhering to the wing position schedule, and climb at that speed until reaching
0.9 Mach, either flying by hand, or using attitude hold to maintain your airspeed.
Maintain 0.9 Mach until reaching 30,000 feet. Level off and accelerate
using full afterburner to approximately 1.2 Mach. Be ready to throttle
back after the aircraft passes through Mach 1.2 as it will accelerate very
quickly. Begin climb to desired altitude, maintaining 450 KIAS. Hold this speed until reaching desired altitude.</font></p>
<p><b><font face="Arial" size="2">Tactical Climb and Transonic Flight -
Descending Flight Technique</font></b></p>
<p><font face="Arial" size="2">At altitudes higher than 30,000 feet, or at very
high aircraft weights, it may be necessary to climb to 33,000 feet at 0.90 Mach,
level off, and then descend to 30,000 feet at 3000 fpm to break through the sound
barrier. Be ready to throttle back after the aircraft passes through Mach
1.2 as it will accelerate very quickly. Begin climb to desired altitude,
accelerating to 450 knots IAS. Hold this speed until reaching
desired altitude.</font></p>
<p><b><font face="Arial" size="2">Cruising</font></b></p>
<p><font face="Arial" size="2">When approaching cruising altitude, reduce vertical speed gradually as to intercept the
desired altitude smoothly and with minimum of pitching. If pitching up and
down (porpoising) occurs, simply turn off the autopilot, stabilize the aircraft
at the desired altitude, and then turn the autopilot back on, ensuring that your
altitude hold value is the same (within a few feet) as the altitude at which you
have stabilized. Set the throttles to obtain the desired cruising speed.</font></p>
<p><font face="Arial" size="2"><b>Fuel Management</b></font></p>
<p><font face="Arial" size="2">Fuel and center of gravity management in the
XB-70 is fully automatic as with the real aircraft. Fuel is stored in the wings and fuselage. No
tank selection or fuel transfer is necessary.</font></p>
<p><b><font face="Arial" size="2">Wingtip Position Schedule</font></b></p>
<p><font face="Arial" size="2">Wingtip position control is manual in this
aircraft. Observe the following schedule for positioning.</font></p>

<p><font face="Arial" size="2"><b>Notes on Cruising in Flight Simulator</b></font></p>
<p><font face="Arial" size="2">Flight Simulator is limited in the degree to
which aircraft weight will affect cruise performance. Weight has a very
small, mostly negligible effect on fuel consumption and range. Thus, the
cruise weight selected will have very little effect on the aircraft's range and
performance. However, all other cruise performance parameters are a very
close match to the real aircraft. For example, at the optimal cruise for
maximum range (see the actual charts from the XB-70 flight manual below), the
specified range at 27,000 feet at 68 percent of military thrust at a speed of
0.85 Mach is 16 nautical miles/1000 pounds of fuel, achieved by setting the
throttles to 38 percent using the ECU index marks (27 percent using the mouse
tooltip). Your AlphaSim XB-70 Valkyrie will match this performance
exactly, the only variation being that aircraft weight will not materially
affect cruise performance. Likewise, setting the throttles to maximum
military thrust (45 percent on the ECU, 35 percent using the mouse tooltip) at
an altitude of 30,000 feet will yield a fuel economy of 11.6 nm/1000 pounds of
fuel, again, an exact match for the real aircraft.</font></p>
<p><font face="Arial" size="2">The variation in supersonic cruise also reflects
that of the actual aircraft, except with respect to weight. A cruise of
3.0 Mach at 75,000 feet will result in a specific fuel consumption of 15.1
nm/1000 pounds, while backing the throttles down to minimum afterburner at the
same altitude will result in a specific fuel consumption of 28.5 nautical miles
per 1000 pounds of fuel. </font></p>
<p><font face="Arial" size="2">The chart information for percentage of either
military or maximum thrust versus throttle index position will vary with
conditions but is a good yardstick. Set throttles as needed to achieve the
Mach number and fuel flow for the desired cruise performance. Use the fuel
flow totalizer to set the throttles and then fine-tune from there.</font></p>
