AND DESIGN REQUIREMENTS CONTINUED
7. Armed Reconnaissance. Since an
armed reconnaissance capability is required and it is visualized that
many of the tasks performed by fixed wing VMO types could also be performed,
provision is made for two seats. The seat for the observer is located
in the bomb bay and can be removed when not in use. Visibility is o
prime importance in an aircraft of this type. Therefore, a configuration
with both seats in front of the wing was decided upon. The wing is set
approximately even with the pilot's shoulders providing 360 degree visibility
above the wing. Un obstructed visibility forward and back under the
wing for a considerable distance gives the pilot the best possible combination.
The observer is limited by the pilot in front of him and the wing behind
him, but he should be able to see almost straight ahead by looking around
the pilot's head and will be able to back under the wing about 30 degrees.
Side by side seating was rejected because it would limit visibility
for the pilot in the attack role. Increased frontal area would also
cause more drag and present a better target.
8. Safety. Because of its small size and moderate speed this airplane
can be made quite strong. It is designed to withstand a load factor
of 10-G so that the pilot needn't worry about exceeding the limits.
The combination of low stall speed and robust construction should make
it relatively safe in the event of a crash landing or ditching. However,
the reliability of the two engines makes forced landings an unlikely
eventuality. Ejection seats are not considered necessary since bail-out
over the side could be accomplished. On an aborted takeoff, a forced
landing would probably be safer than ejection because of the low speed.
This airplane should be safe and easy to fly, thus enabling the pilot
to concentrate on tactical training rather than long check-outs and
involved instrument procedures. While instrument flying will be provided,
it is considered that this type of aircraft should be flown VFR exclusively
in combat. Operations are possible with a ceiling of 200 feet with one-half
mile visibility and dive bombing can be conducted with a 2,000ft ceiling.
While operations will not be possible 100% of the time, they will be
possible a higher percentage of the time than in current attack types
and, moreover, without the necessity of any landing aids like CGA.
9. Transport to the Area of Operations. For transport to the
area of operations there are a series of choices. With ferry fuel tanks
a range of over 2,000 miles can be obtained at a cruising speed of about
240kt at approximately 25,000ft. If a carrier deck were available, of
course, the airplane could fly off with ease and it should be noted
that storage space required would be small. While the first experimental
aircraft will not have this feature, it is quite feasible to design
the various components so that it can be disassembled easily and stored
in a box that would fit in a 6x6 truck bed together with the equipment
needed for re-assembly in the field. It could thus be transported by
amphibious shipping and either heli-lifted or driven ashore by a 6x6
10. Deep Rescue. The airplane has what appears to be a very good
capability for deep rescue in enemy territory. The STOL characteristics
would permit landing near a downed pilot who could enter the plane rapidly
through the bomb bay doors. The armor, low radiation return and relative
high cruising speed compared to a helicopter would make it valuable
at long ranges in spite of the fact that the helicopter's ability to
hover would over-balance these factors at short ranges.
11. Communications is always a problem in combat. In this case
it appears that the provision of a standard UHF a/c radio would permit
control through ANGLICO facilities and communication with high performance
aircraft. The UHF facilities could be used for overriding central control
by a TACC for rescue or emergency. It would also be used to control
high performance a/c on targets where their heavier ordnance was necessary,
adding an airborne controller to the ANGLICO capability. L.F. radio
of some sort is also required in order that intelligence and gunfire
spotting missions can be accomplished. This should not pose a difficult
problem. In most cases organic infantry communications equipment could
be used and, in addition, there is space in the back bomb bay for it.
