A 68 kg (150 lb) person walking at 4 km/h (2.5 mph) requires approximately 210 kilocalories (880 kJ) of food energy per hour, which is equivalent to 4.55 km/MJ. [15] 1 US gal (3.8 L) of petrol contains about 114,000 British thermal units (120 MJ) [52] of energy, so this is approximately equivalent to 360 miles per US gallon (0.65 L/100 km).
While the external payload remained at 24 of 500 pounds (230 kg) or 750 pounds (340 kg) bombs, the internal capacity increased from 27 to 84 for 500 lb (230 kg) bombs, or from 27 to 42 for 750 lb (340 kg) bombs. [168] The modification created enough capacity for a total of 60,000 pounds (27,000 kg) using 108 bombs.
[N 16] With 18,000 lb (8,165 kg) of internal fuel and an additional 8,000 lb (3,629 kg) in two 600-gallon external tanks, the jet has a ferry range of over 1,600 nmi (1,840 mi; 2,960 km). [142] The aircraft has a refueling boom receptacle centered on its spine and an auxiliary power unit embedded in the left wing root.
The cockpit and parts of the flight-control systems are protected by 1,200 lb (540 kg) of titanium aircraft armor, referred to as a "bathtub". [ 67 ] [ 68 ] The armor has been tested to withstand strikes from 23 mm (0.91 in) cannon fire and some indirect hits from 57 mm (2.2 in) shell fragments.
On May 12, 1996, Arie Luyendyk, while driving an IndyCar powered by a Ford Cosworth XB engine, broke the Indianapolis 500 records for fastest qualification lap (237.498 mph; 382.216 km/h) and fastest qualification four-lap average (236.986 mph; 381.392 km/h). [195] [196] These speed records still stand as of 2022. [197]
Meanwhile, its dynamic braking effort is as much as 105,000 pounds-force (470 kN). The amount of starting tractive effort is equal to that of the 6,000 horsepower (4,500 kW) SD90MAC-H while, on the other hand, its continuous tractive effort is higher than that of the SD90MAC-H (175,000 pounds-force (780 kN) vs. 165,000 pounds-force (730 kN)).
