Turbulence in Flugzeugen

The video discusses the dangers of turbulence during flights, the different types of turbulence, and how airlines are working to protect their passengers from it.

Types of Turbulence

• There are four different intensities of turbulence: light, moderate, severe, and extreme.

• Light turbulence causes minimal movement in the aircraft and is barely noticeable to passengers.

• Moderate turbulence causes more noticeable movement in the aircraft and can cause unsecured items to move around.

• Severe turbulence can cause abrupt changes in flight position and even cause passengers to be thrown from their seats.

• Extreme turbulence is rare but can cause complete loss of control over the aircraft.

Causes of Turbulence

• Turbulence can be caused by friction with terrain or artificial obstacles such as buildings or trees.

• Near mountains, mountain waves or lee waves can create turbulent conditions on both sides of a mountain range.

• Special weather conditions such as thunderstorms can also create turbulent conditions.

• Clear-air turbulence occurs at high altitudes where there are no clouds. It is often found near jet streams.

Impact on Passengers

• Turbulence is a leading cause of injuries during flights.

• Airlines are working to protect their passengers from injury by researching new technologies that will help prevent turbulence-related accidents.

• Airlines have been hesitant to invest in these technologies due to cost concerns.

Turbulence and Climate Change

This section discusses the impact of climate change on turbulence during flights, as well as a new technology called turbulence cancelling.

Turbulence and Climate Change

• Clear air turbulence is responsible for most severe incidents during flights.

• The increase in temperature in the upper troposphere and decrease in temperature in the lower stratosphere due to climate change will lead to more turbulence, especially in mid-latitudes where most planes fly.

• There will be a 160% increase in severe turbulence between 2050 and 2080 compared to pre-industrial times.

• Turbulence causes an additional 10% of CO2 emissions from airplanes.

Turbulence Cancelling

• Turbulence cancelling is a new technology that can reduce turbulence by up to 80%.

• The inspiration for this technology comes from birds' feathers, which act as sensors for detecting changes in airflow.

• Sensors are mounted on poles attached to the wings of airplanes that detect changes in air pressure caused by turbulence before it reaches the wings.

• These sensors send signals to movable flaps on the wings that can adjust within 0.1 seconds to counteract turbulence, similar to how birds adjust their feathers.

• This technology is faster than traditional flaps, which are 20 times slower.

• The first passenger flight with turbulence cancelling is expected to take place in summer.

LIDAR Detection

• LIDAR detection uses short laser pulses that bounce off aerosols (small particles) in the air to detect changes in frequency caused by movement of these particles due to turbulence.

• Boeing has been testing this system for several years and it can detect turbulence up to 16 km away.

• This system could complement or replace Differenzdrucksensors used for measuring air pressure changes caused by turbulence.

Traveland Solution's Turbulence Cancelling Technology

This section discusses how Traveland Solution's turbulence cancelling technology is currently only focused on small planes due to their low altitude, which makes them more susceptible to turbulence. The startup plans to eventually expand the technology to larger planes, but this may take up to 10 years. However, the cost of implementing this technology is currently a major obstacle.

Focus on Small Planes

• Traveland Solution's turbulence cancelling technology is currently only being used for small planes due to their low altitude and susceptibility to turbulence.

• Experts from Trouble and Scansling have noted that small planes are particularly affected by turbulence.

Expansion Plans

• Traveland Solution plans to eventually expand its turbulence cancelling technology to larger planes as well.

• However, it may take up to 10 years for this expansion plan to come into effect due to issues with ensuring operational safety in large planes.

Cost Obstacles

• The cost of implementing the turbulence cancelling technology in large planes is a major obstacle at present.

• Currently, using Differenzdrucksensoren (differential pressure sensors) is about ten times cheaper than using the turbulence cancelling system developed by Traveland Solution.

• Research has shown that installing the system would actually cost more money than it would save in the long run, making it unfeasible for many airlines.

Turbulence-related Injuries and Future Developments

This section discusses how turbulence can cause injuries and financial losses for airlines and employees alike. It also explores potential future developments in aviation safety.

Turbulence-related Costs

• Turbulence can cost airlines millions of dollars each year and lead to thousands of hours of employee absence due to injuries.

• This makes it important for airlines to invest in technologies that can prevent turbulence-related injuries and losses.

Future Developments

• Technologies like turbulence cancelling systems and turbostabilizing could help reduce fuel consumption and increase safety on flights.

• However, these technologies are currently too expensive for widespread use, so it may be some time before they become more accessible.

• Hydrogen-powered planes may also be a promising development in the future of aviation.
