In some embodiments of the invention, methods and devices are provided that perturb a trajectory of a space-orbital object. For example, a spacecraft may be sent to a location near a space-orbital object orbiting the Earth. A net may be released from the spacecraft in a manner (e.g., with a given alignment, direction and velocity) that results in the net contacting and/or entangling with the object. This contact or entanglement may alter a velocity of the space-orbital object and thereby may alter its orbital path. In some instances, the net's velocity is sufficient to experience increase drag by the Earth's atmosphere, relative to the drag it would have otherwise experienced if the net did not contact the object.

The invention discloses a long-acting vacuum satellite, and particularly relates to a flight device which uses a vacuum chamber as a floating device and can float in atmosphere for a long time. A vacuum airship manufacturing theory is not a novel theory, but a vacuum airship does not exist in the world so far, because the vacuum chamber which can bear atmospheric pressure cannot be manufactured on the ground through current materials and current technologies. According to the vacuum satellite disclosed by the invention, the characteristic that the higher the altitude of the earth atmosphere is, the lower the air pressure is is adopted, so that the vacuum chamber can be lifted to a high altitude and then is vacuumized. The characteristic that the atmospheric pressure in the high altitude is low so that the air pressure difference is insufficient to damage the vacuum chamber is adopted, therefore, the aircraft can float in the atmosphere for a long term, and some work of a man-made satellite is replaced.

An active vortex control system (AVOCS) includes a set of primary injectors that inject gas into a cavity to generate a vortex in front of and possibly around components inside the cavity. The vortex interferes with an external flow field in an opening to the cavity to protect the components from the external environment. Sets of secondary injectors may inject gas at a reduced mass flow into the cavity to compensate for energy losses to maintain the coherence of the vortex. The AVOCS is well suited for use in windowless endo- and exo-atmospheric interceptors to protect the electro-optical imagers and optical components from Earth atmosphere.
