Parachute Ejection via Gas Pressure for Reliable Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parachutes for flying bodies often fail to open reliably when there is no immediate airflow effect during flying or falling, posing a safety risk, especially for larger multi-rotor rotary wing aircraft.
Innovation Solution
A parachute device with a tubular parachute accommodation section, connected flying bodies, a gas generating device, and a gas introduction path, where the gas generating device produces gas to eject the flying bodies, which in turn deploy the parachute, ensuring reliable opening even without immediate airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional parachute is designed to be easily opened by air current during flying, then the parachute can open naturally during normal flight, but the parachute fails to open reliably when there is no immediate airflow effect during falling
Solution Approach 1:
The gas generating device is activated in advance before the parachute needs to open, storing pressurized gas in the gas storage section. This preliminary action ensures that when the flying body needs to be ejected, the gas is already prepared and can immediately propel the flying body outward, triggering parachute deployment without waiting for airflow effects.
Solution Approach 2:
The invention uses a gas generating device and gas storage section to create pressurized gas, which is then used to eject the flying body through the ejection section. This pneumatic system replaces reliance on natural airflow, providing a controlled and reliable mechanism for parachute deployment regardless of external air current conditions.
2Quantity of substance
If the body size of the rotary wing aircraft is increased to transport larger loads, then the transport capacity is improved, but the risk of severe damage during uncontrollable falling increases
Solution Approach 1:
The parachute system is pre-configured and ready for deployment before any emergency occurs. The gas generating device is prepared in advance, and the flying bodies are positioned within the ejection section, ensuring that when an emergency landing is needed, the parachute can be deployed immediately to mitigate damage from the increased weight and size of the aircraft.
3Speed
If the parachute is designed to rely on airflow effects for opening, then the device structure can be simpler, but the response time is delayed when airflow effect is not immediately obtained
Solution Approach 1:
The invention employs a gas-powered ejection mechanism where pressurized gas from the gas generating device is stored and then used to rapidly eject the flying bodies through the ejection section. This pneumatic system provides fast, controlled propulsion that is not dependent on external airflow conditions, achieving rapid parachute deployment while maintaining a manageable device structure.

Function Achieved in This Case
Enables the parachute to open and deploy reliably, ensuring a safe descent of the aircraft by utilizing the generated gas to eject the flying bodies and deploy the parachute, even in the absence of immediate airflow effects.
Implementation Method 1
a gas generating device fixed at the parachute accommodation section and configured to generate gas, and a gas introduction path configured to introduce the gas generated from the gas generating device to an interior of the ejection section
