Blowing Up an Airplane Tire | I Didn't Know That | Summary and Q&A

TL;DR

Aircraft tires undergo rigorous testing, including overinflating them to more than four times their normal pressure, to ensure their strength and integrity.

Key Insights

• 🚄 Aircraft tires are highly engineered structures designed to carry heavy loads at high speeds.
• 😪 Dunlop has been designing and making aircraft tires since 1910.
• 🚕 Testing on a dynamometer simulates taxiing, takeoff, and landing conditions.
• 😪 Overinflating aircraft tires to more than four times their normal pressure is a dangerous test.
• 💦 Water is used for the burst test instead of air to prevent damage to surrounding buildings.

Questions & Answers

Q: Why are aircraft tires subjected to enormous pressures and friction?

Aircraft tires need to carry heavy loads at high speeds, which puts them under significant pressure and subject to friction from the aircraft's movement.

Q: How does Dunlop test their aircraft tires?

Dunlop performs rigorous tests on a dynamometer that simulates taxiing, takeoff, and landing conditions. They also overinflate the tires to more than four times their normal pressure to check their strength and integrity.

Q: Can aircraft tires be inflated with air instead of water for the burst test?

No, inflating the tires with air would generate a significant volume of air that could cause damage to surrounding buildings. Water is used instead to conduct the burst test safely.

Q: What happens to an aircraft tire when it is overinflated?

When an aircraft tire is overinflated, it bursts. However, the specific type of tire being tested can reach over four times its normal operating pressure before bursting and still retain its basic form.

Summary & Key Takeaways

• Aircraft tires are designed to carry heavy loads at high speeds, subjecting them to enormous pressures and friction.

• Dunlop aircraft tires in Birmingham hand-make tires for all types of aircraft and perform tests that push the tires beyond their operational safety limits.

• The most impressive test involves overinflating the tires to more than four times their normal pressure to check the strength and integrity of the casing.
