Abstract:
An apparatus and a method for inspecting navigation safety facilities by using a flight vehicle are disclosed. The method for inspecting navigation safety facilities by using a flight vehicle comprises the steps of: defining a three-dimensional flight path for a flight vehicle so that same passes through navigational safety facilities; receiving a navigation signal value from the navigation safety facilities and GPS data of the flight vehicle, the navigation signal value and the GPS data being measured by the flight vehicle automatically flying along the defined three-dimensional flight path; analyzing the navigation signal value so as to estimate the distance and the angle of the flight vehicle viewed from the navigation safety facilities; and inspecting the navigation safety facilities according to whether the coordinates of the flight vehicle identified by the GPS data are included in an area formed by the distance and the angle.

Abstract:
A friction-type drive apparatus and a carousel comprising the same are disclosed. A friction-type drive apparatus, according to one embodiment, comprises: a motor; a drive pulley rotated by the motor; a belt connected to the drive pulley; a driven pulley rotating in accordance with the drive of the belt; a pressing unit contacting the inner surface of the belt; and an elastic unit for pressing the pressing unit toward the belt.
Abstract:
According to the present invention, a height adjustment device for adjusting a rotunda of a boarding bridge is provided. The rotunda height adjustment device for a boarding bridge comprises: an external column fixed to the ground and having an inner space formed therein; an internal column which fixes a rotunda, and which is coupled so as to be slidable in the inner space such that rising and lowering is enabled; a driving unit which makes the internal column move vertically and translationally with respect to external column, and which is provided so as to be exposed to the outside of the external column and the internal column; and a power unit for controlling the driving unit. Therefore, the rotunda height adjustment device can be inspected, repaired for a defect thereof, and easily replaced.
Abstract:
An electrically scanned TACAN antenna is provided. To elaborate, the electrically scanned TACAN antenna includes a reflection plate; a monopole antenna provided on an upper surface of the reflection plate and configured to omnidirectionally radiate a signal; multiple parasitic radiators arranged around the monopole antenna and configured to operate as reflectors that reflect the signal or directors that direct the signal; and a controller configured to control parasitic radiators operating as the reflectors to operate as the directors and some parasitic radiators among parasitic radiators operating as the directors to operate as the reflectors at every predetermined timing and controls an order to be the some parasitic radiators to be changed according to a preset sequence.
Abstract:
A dual-sloping carousel is disclosed. According to the present invention, the carousel comprises forward-sloping and reverse-sloping sections, so as to reduce the risk of falling baggage, thereby preventing the baggage from being damaged.
Abstract:
A movable boarding bridge is disclosed. The movable boarding bridge comprises: an inner tunnel; an outer tunnel disposed on an outer surface of the inner tunnel so as to slide on the inner tunnel; a roller arranged on the external surface of the inner tunnel; and a rainwater gutter-type rail arranged on the internal surface of the outer tunnel, and configured to guide the roller such that the roller moves along the rail and to allow inflowing rainwater from the outside to flow therethrough, wherein the rainwater gutter-type rail may be configured such that the rainwater gutter is not seen from the inner tunnel through which passengers pass.
Abstract:
A rainwater receiver of a movable boarding bridge may comprise rainwater receivers provided at: an outer tunnel; an inner tunnel disposed inside the outer tunnel; an inner tunnel footpath equipped in the inner tunnel and configured in the form of a footpath so that passengers can walk thereon; an outer tunnel footpath disposed at the lower end of the inner tunnel footpath and configured in a multilayer form; and the lower end of the outer tunnel footpath. A tunnel path part of the movable boarding bridge configured as above is positioned to be separated from the rainwater receivers so that the rainwater receivers are not seen by passengers inside a tunnel. In addition, since there is no height difference caused by the rainwater receivers, there is an advantage in that problems such as passengers' sprained ankles can be resolved.
Abstract:
A data processing device and method are provided for measuring a radio wave of an instrument landing system (ILS). To elaborate, the device includes: a location receiver configured to receive location data of an ILS antenna measured by a GPS receiver; a radio wave receiver configured to receive radio wave data measured by the ILS antenna; a data processor configured to perform mutual mapping between the location data and the radio wave data; and a storage configured to store mapping result data of the data processor. The data processor generates a 3D image of the radio wave data measured from multiple measurement paths of the ILS antenna located at a certain point on the basis of the mapping result data.
Abstract:
An automatic slope adjusting device is provided herein. The automatic slope adjusting device may include a slope type footrest unit configured to form a sloped passage; and a driving unit configured to adjust an inclination angle of the slope type footrest unit, and a length of the slot type footrest unit in a forward-backward direction thereof.
