How do I maintain the BRS? |
BRS maintenance includes the following three steps: Step 1. The system must be inspected once a year; Step 2. The parachute must be replaced by BRS technicians once every 10 years (mainly refers to parachute collection). The parachute wiring must also be reinstalled and inspected. Step 3. The replacement costs $1,000 (USD) every 10 years. If the parachute system is subject to abnormal stress or exposure (physical damage), an additional fee will be charged. All prices are listed herein for your reference, and no prior notice will be provided for any changes. |
What in-flight tests has the BRS undergone? |
The system has undergone 35 air vehicle tests. The in-air tests include: Low-speed approach without power Left and right extreme turns Cruising speed at 100 knots Turning at 2G Not exceeding the speed limit (Vne) The Cirrus SR20 has undergone eight different aircraft tests pursuant to FAA criteria, including: Low-speed approach without power Left and right extreme turns Within maneuvering speed (135 knots) Note: The safe speed of the parachute of the Cirrus SR20 is 135 knots (155 mph). In case the weight of an aircraft exceeds 125% of its net weight, the speed may reach 190 mph, and the survival opportunity depends on the flying speed. |
Are there any other tests? |
The components of the BRS-172 have undergone various engineering studies, including load testing and limit loading. Various studies have reported the tension and strength of the parachute material, "slider," and components of the BRS. The pull rod of the BRS has also been tested by different people. The seats and seat belts have also been tested for various safety considerations when the parachute is opened and the aircraft is landed. This system is specially designed to ensure the safety of its personnel upon hard landing. These tests are designed to ensure the safety of users. These tests involve "landing status", meaning a high-speed cameras is used under a safe and controlled environment to record data about the aircraft and the user at landing. Other tests include the influence on the whole system by the action of the hand lever, environmental risk factors, and fire. |
Is there any patent on the BRS? |
Yes, the “Slider” is under patent #4,863,119. The "Slider" mainly describes the velocity response, vibration attenuation, and dynamic induction system because its physical property is just like sliding down off the main chute. Its main feature is the automatic speed sensing function, which allows it to solve some complicated problems if necessary. In general, the Slider is installed inside the main chute and will not cause any adverse effects. When the parachute is deployed at a low speed of flight, it can prevent rapid deployment of the parachute. |
What is BRS? |
BRS is a company based in South St. Paul's Airport, Minnesota, and its stock code is BRSI. More than 20,000 BRS systems have been sold since the 1980s. |
