- Cargo capacity – the SOAR research aircraft is
capable of carrying a load of 1000 pounds in
addition to a scientific crew of four persons and
maximum fuel.
- Maximum altitude – the maximum altitude of the
SOAR research aircraft is its service ceiling at
31,600 feet for a minimum on-station time of 3.5
hours.
- Range - the SOAR research aircraft has a maximum
range of 1200 nautical miles.
- Endurance - the SOAR research aircraft has an
endurance of 5 hours at scientific payload.
- Rate of climb – the climb capability of the SOAR
research aircraft at ISA carrying the scientific
payload is 2000 feet per minute.
- Research power – The aircraft main power is
connected to a main DC buss through a Cutler Hammer
Relay, then to the Main Power Cable connected to a
Power Distribution Rack Case which contains switch
breakers for individual system components including
de-icing power and 115V AC power. The research power
available on the 28V DC supply is 6.7kW and on 115V
AC supply is 1kW.
- Hard points – The SOAR research aircraft is
modified with two hard points (one per wing). The
following design describes the specifications of
each wing hard point:
Maximum Weight: 60 pounds
Center of Gravity: FS 137.0, BL 178.625
Maximum Moment Arm to Wing Undersurface: 10.4 inches
Equivalent Flat Plate Drag Area: 0.07 square feet
Skin doublers in the wing undersurface and in the
fuselage are designed for a variety of probes and an
air inlet port for air sampling inside the
pressurized cabin.
- Crew – the aircraft crew consists of a pilot, a
data system operator and up to two scientific
observers. An instrument technician usually
accompanies the crew in the field.
- Research speed - the SOAR research aircraft has
a research speed of 70 to 100 m/s. This speed can
be adjusted to fulfill each research task.
