It burns 160-200 gallons per hour
The B-17 Flying Fortress is a formidable machine with impressive statistics. With a maximum weight of 54,000 pounds, its six wing-mounted fuel tanks can hold a total of 1,700 gallons of fuel. On average, the B-17 burns through 160 to 200 gallons of fuel per hour, resulting in an endurance of 8.5 to 10 hours and a range of 1,350 to 1,600 nautical miles.
The fuel efficiency of the B-17 is a testament to its design and engineering. Its four nine-cylinder, 1,200-horsepower Wright Cyclone R-1820 engines generate tremendous power while consuming a relatively moderate amount of fuel. This efficiency allows the aircraft to stay airborne for extended periods, providing the necessary endurance for long-range missions.
The B-17's fuel efficiency also contributes to its operational flexibility. With a cruising speed of 170 miles per hour, the aircraft can cover vast distances while consuming fuel at a steady rate. This enables mission planners to accurately estimate fuel requirements and plan accordingly, ensuring that the aircraft has sufficient fuel to reach its target and return safely.
Additionally, the B-17's fuel efficiency played a crucial role in its wartime capabilities. During World War II, the B-17 was utilized as a heavy bomber, often undertaking long-range missions deep into enemy territory. The aircraft's fuel efficiency allowed it to carry a substantial bomb load while still maintaining the endurance necessary to reach distant targets and return to base.
The B-17's fuel consumption rate of 160 to 200 gallons per hour is a critical factor in understanding its performance characteristics. This efficiency, combined with its substantial fuel capacity, contributes to the aircraft's overall range and endurance, making it a versatile and formidable weapon in the hands of a skilled pilot.

Endurance is 8.5-10 hours
The Boeing B-17 Flying Fortress is a formidable aircraft with an impressive range. With a maximum gross weight of 54,000 pounds, the B-17's six wing-mounted fuel tanks can hold up to 1,700 gallons of fuel. This fuel capacity translates to an endurance of 8.5 to 10 hours in the air, depending on various factors.
The B-17's fuel consumption varies, burning between 160 to 200 gallons of fuel per hour. This range in fuel burn rate contributes to the variation in the aircraft's endurance. At the most efficient rate of 160 gallons per hour, the B-17 can stay airborne for up to 10 hours. However, if the fuel burn rate increases to 200 gallons per hour, the endurance decreases to 8.5 hours.
The endurance of the B-17 is also influenced by factors such as speed, altitude, and payload. For example, at a cruising speed of 170 mph, the aircraft's endurance is expected to be towards the higher end of the range. Additionally, the B-17 was designed to carry a "useful bomb load" at an altitude of 10,000 feet for 10 hours, which aligns with its endurance capabilities.
The B-17's endurance played a crucial role during World War II, allowing it to undertake long missions and contribute significantly to the war effort. Despite its vintage, the B-17 remains an impressive aircraft, with only about a dozen still airworthy today, making each flight a rare privilege for pilots.
In summary, the endurance of the B-17, ranging from 8.5 to 10 hours, is a testament to its design and capabilities. With its substantial fuel capacity and efficient fuel burn rate, the B-17 Flying Fortress continues to capture the imagination of aviators and enthusiasts alike.

Range is 1350-1600 nautical miles
The B-17 Flying Fortress is an impressive machine with a maximum gross weight of 54,000 pounds. It has six wing-mounted fuel tanks with a total capacity of 1,700 gallons, burning an average of 160 to 200 gallons per hour. This gives the B-17 an endurance of 8.5 to 10 hours and a range of 1,350 to 1,600 nautical miles.
The B-17 was designed and built by Boeing to meet the USAAC's proposal for a multi-engine bomber that could reinforce air forces in Hawaii, Panama, and Alaska. The Air Corps desired a bomber capable of carrying a "useful bomb load" at an altitude of 10,000 feet for 10 hours, with a top speed of 200 mph. The B-17 exceeded these expectations, with a maximum speed of 300 mph at 30,000 feet and a cruising speed of 170 mph.
The B-17's range and endurance are due in part to its efficient fuel usage. With a maximum fuel capacity of 1,700 gallons, the B-17 can fly for up to 10 hours on a single tank of fuel. This efficiency, combined with its heavy defensive armament and four-engine design, made the B-17 a formidable weapon during World War II.
The B-17's long-range capabilities were demonstrated in January 1938 when Colonel Robert Olds of the Army Air Corps flew a B-17 from the US east coast to the west coast in just 13 hours and 27 minutes, setting a new transcontinental record. The B-17 was also used for goodwill flights to South America and well-publicized missions to intercept and photograph Italian ocean liners.
Today, only about a dozen B-17s remain airworthy, but they continue to be flown and maintained by organizations like the Experimental Aircraft Association (EAA), which offers recurrent training for B-17 pilots and brings the aircraft to communities around the country through its air tour program.

Fuel consumption depends on the mission
The fuel consumption of the B-17 Flying Fortress depends on the nature of the mission. The aircraft was designed and built by Boeing to meet the USAAC's proposal for a multi-engine bomber with a "useful bomb load" capable of flying at an altitude of 10,000 feet for 10 hours with a top speed of 200 mph.
The B-17's fuel consumption averages 160 to 200 gallons per hour, giving it an endurance of 8.5 to 10 hours and a range of 1,350 to 1,600 nautical miles. This range can be extended with the addition of underwing fuel tanks.
The B-17's fuel consumption will vary depending on its speed. At a cruising speed of 170 mph, the B-17 burns fuel at a slower rate, while at its maximum speed of 300 mph, it consumes more fuel. The weight of the aircraft and its payload will also impact fuel consumption, with a heavier load requiring more fuel to maintain altitude and speed.
During World War II, the B-17 was used for a variety of missions, including long-range navigation flights, goodwill flights to South America, and photographing Italian ocean liners. The nature of the mission would determine the fuel load required, with longer missions necessitating more fuel. For example, a typical B-17G mission to targets in Eastern Germany would burn through 2,200 US gallons of fuel in 7 hours and 55 minutes.
