Airbus A400M Atlas
The Airbus A400M Atlas is a four-engine turboprop transport aircraft. The cargo box of A400M Atlas is 17.71 m long excluding ramp, 4.00 m wide, and 3.85 m high (or 4.00 m aft of the wing.
It features a fly-by-wire flight control system with side stick controllers and flight envelope protection. Like other Airbus aircraft, the A400M has a full glass cockpit.
The A400M’s wings are primarily carbon fiber reinforced plastic. The Ratier-Figeac FH385 propellers turn counterclockwise and FH386 clockwise.
The eight-bladed scimitar propellers are made from a woven composite material. The aircraft is powered by four Europrop TP400-D6 engines rated at 8,250 kW (11,000 hp) each.
The TP400-D6 engine is to be the most powerful turboprop engine in the West to enter operational use
The pair of propellers on each wing of the A400M turn in opposite directions, with the tips of the propellers advancing from above towards the midpoint between the two engines. This is in contrast to the overwhelming majority of multi-engine propeller-driven aircraft where all propellers turn in the same direction.
The Antonov An-70 is a four-engine medium-range transport aircraft
The An-70 is a monoplane with a high-mounted wing design that features four distinctive propfan engines.
Each of the D-27 engines is rated at 16,000 shp
The propfan engines deliver slipstream to the supercritical wings that feature double-slotted trailing edges to provide high lift coefficients at low speeds.
The aircraft’s cruise speed is 750 km/h at an operational altitude of 8,600 to 9,600 m
In short take-off and landing (STOL) configuration, the aircraft could lift off from a 600 m dirt strip with 25 tonnes of cargo and fly for 3,000 km.
Alternatively, it could fly the same distance with 35 t of cargo if it took off from a 1,800 m paved runway.
For a payload-heavy mission, the An-70 can haul 47 t of cargo for a range of 1,500 km, but if the range was essential, the aircraft can carry a load of 17 t over 8,000 km
