A system for slowing down the speed of flying objects by applying electrodynamic and aerodynamic braking forces. The system is comprised of plurality of stubs, where each stub is made of dielectric material surrounded by metal foil and another metal foil is inserted in the middle of the stub, where the outer metal foil and the inner metal foil are isolated from each other, so that they form a capacitor. Each stub is stored in a barrel before being used. When activated, the stubs are stretched from the barrel as a tail behind the flying object. The area of the stub generates aerodynamic drag. The stub capacitor is charged by a generator so that free electrons are present in the outer metal layer of the stub. The electric field produced by these charges interacts with ions in the atmosphere.

Technologies for providing emergency egress routes for a blended wing body aircraft are described herein. In some examples, the emergency egress routes are through a side cabin bulkhead and aft one or more cargo holds. In some examples, the blended wing body aircraft has wings that are high geometry wings. In these examples, the emergency egress routes do not penetrate an aft spar, reducing weight and increasing the integrity of the aircraft.

An aircraft safety system includes impact energy reduction systems including: an aircraft parachute, at least one rotor configured for autorotation, and an energy absorbing system. An automatic control system uses data from speed and altitude sensors to selectively and sequentially deploy the impact energy reduction systems depending on the portion of the aircraft speed and altitude flight envelope in which the aircraft is operating when an emergency is detected.

A system includes a turbo pump to convert compressed gas into power, a storage tank to store the compressed gas, and a fire suppression control valve having a closed position in which the compressed gas is prevented from flowing to the cargo compartment and an open position in which the compressed gas is ported to the cargo compartment to suppress a fire. The system also includes a pump control valve having a closed position in which the compressed gas is prevented from flowing to the turbo pump and an open position in which the compressed gas is ported to the turbo pump to cause the turbo pump to convert the compressed gas into the power. The system also includes an OBIGGS to convert bleed air from a gas turbine engine into an inert gas to provide low rate discharge (LRD) fire suppression to the cargo compartment.

Apparatus and associated methodology contemplating an emergency flotation system for floating a flying machine on a body of water. The system includes a water sensor mounted to the flying machine. An inflation device is configured to produce an appropriate amount of pressurized gas in response to the water sensor detecting a presence of water. An inflatable flotation device is in fluid communication with the inflation device, to receive the pressurized gas and thereby become inflated. The flotation device is configured, when inflated, to impart a buoyant force to the flying machine in the water.
