TL;DR: In this paper, a capsule is used for the recovery of liquid propellant rocket engines, so that they can be reused once or more times, in first stages (one-and-a-half) boosters.
Abstract: This recovery system is used mainly for the recovery of liquid propellant rocket engines, so that they can be reused once or more times, in first stages (one-and-a-half) boosters. The technological goal of this invention is improved reliability of recovery systems. This goal is achieved by the rocket engine recovery system representing of a capsule comprised of a protective bottom and a lateral cover; the capsule includes a parachute bay and a landing gear bay; the capsule is attached to the engine thrust frame; at least one stabilizing parachute; at least one main parachute; at least one landing set of landing gear; the bay with the landing gear is located in the protective bottom of the capsule; the parachute release, the landing gear inflation, and the soft landing engines ignition are initiated, using simplest automatic devices.

TL;DR: In this paper, a miniature multi-rotor aircraft capable of taking off from and landing on water and land and being self-charged in the technical field of small-size aircrafts is described.
Abstract: The invention discloses a miniature multi-rotor aircraft capable of taking off from and landing on water and land and being self-charged in the technical field of small-size aircrafts An inflating module, a charging module and a release module are installed on the miniature multi-rotor aircraft, wherein the inflating module is installed on a landing gear at the bottom of the multi-rotor aircraft and consists of a gas generator, miniature electronic valves, gas transmission pipes and airbags which are installed on landing gear bottom rods; the charging module consists of miniature solar energy receiving panels arranged on the surface of the rack of the aircraft, an energy management and a battery; and the release module is connected with the landing gear bottom rods and the airbags The miniature multi-rotor aircraft capable of taking off from and landing on water and land and being self-charged has the characteristics of light weight and small resistance during flying in air and high stability of landing in water, can be widely used for image pickup, environmental detection, field rescue and the like in spaces above water surfaces, and has a wide prospect

TL;DR: In this paper, the authors describe the navigation and guidance system developed for the TCV B-737, a Langley Field NASA research aircraft, and present the results of an evaluation during final approach, landing, rollout and turnoff obtained through a nonlinear digital simulation.
Abstract: This paper describes the navigation and guidance system developed for the TCV B-737, a Langley Field NASA research aircraft, and presents the results of an evaluation during final approach, landing, rollout and turnoff obtained through a nonlinear digital simulation. A Kalman filter (implemented in square root form) and a third order complementary filter were developed and compared for navigation. The Microwave Landing Systems (MLS) is used for all phases of the flight for navigation and guidance. In addition, for rollout and turnoff, a three coil sensor which detects the magnetic field induced by a buried wire in the runway (magnetic leader cable) is used. The outputs of the sensor are processed into measurements of position and heading deviation from the wire. The results show the concept to be both feasible and practical for commercial type aircraft terminal area control.
