 NHỮNG ĐẶC TÍNH ĐỘC ĐÁO CỦA MÁY BAY VẬN TẢI C-7 CARIBOU DO ÚC CHẾ TẠO.


Given the availability of an Army 6 by, this was the standard method of loading and unloading a Caribou. Unfortunately, we rarely had the use of the truck in the boonies. This photo was taken at Ham Tan.

The prop hub of the mighty Pratt & Whitney R-2000 7M2.
The mighty Pratt & Whitney R2000 7M2. This particular one was sick enough that I had to throttle it back to idle and fly a single engine approach. Picture taken on the ramp at Bien Hoa.
VÌ ĐỘNG CƠ NÀY HƯ, NÊN CHỈ BAY BẰNG 1 MÁY. 
This picture, taken on the ramp at Cam Ranh Bay, shows the flaps at full extension. One can clearly see that the entire trailing edge of the wing is part of the flap system. One can also understand why one had to point the nose at the ground to get the thing down with the flaps fully extended.
The augmentor tubes on the top of the Caribou engine nacelle.  These large tubes served to collect the 14 individual exhaust stacks and direct the exhaust gas out over the rear edge of the wing.  Since  they were open at the front where the stacks entered, a venturi effect resulted which drew in outside air to mix with the exhaust gas.  This served not only to help cool the very hot exhaust, but also actually added a little extra thrust.
This is the Petester fueling his own airplane.  Actually, it was a major nuisance and the crew members each took turns.  The fuel tanks were filled with an open cell foam material to make them less likely to explode if penetrated by a projectile, so the fuel would not run in at the rate the fuel truck would pump.  The fueller had to constantly stop the flow to allow the gas to seep out through the foam.  Since it took quite a while and the top surface of that wing was very hot, this was not the most desirable of jobs.
Long range flying wasn't exactly uppermost in the minds of the Caribou's designers.   When long overwater flights were necessary, additional fuel and oil was carried in the cargo compartment.  The rubber fuel bladders were filled with avgas and then pressurized with the deicing pumps.  As fuel was burned from the wing tanks, more could be added by operating the valves shown at the right.  This particular picture was taken somewhere along the route from Cam Ranh Bay to Kadena AFB in Okinawa (by way of Clark AB in the Philippines).

Off loading at Gia Nghia after the first sortie of the day. Gia Nghia was the site of an Army Special Forces camp that needed the fuel we brought in the red drums. The airport was unique - they had      knocked the top off a small mountain to provide a generous (for a Caribou) 2000' foot dirt strip. The red soil visible in the foreground was typical of Central Vietnam and was called "laterite" because of its tendency to harden (laterize) into a rock-like surface once defoliated and exposed. When the Caribou's engines were reversed during landing at fields like this, the airplane would disappear into a large red cloud of dust.
