|Patent application number||Title||Published|
|20130313363||Surface Structure on a Ground Surface for Accelerating Decay of Wake Turbulence in the Short Final of an Approach to a Runway - The invention relates to a surface structure on a ground surface (||11-28-2013|
|20130176049||SOLAR GENERATOR - A solar generator for spacecraft or satellites, including a solar panel, a detector layer, a first evaluation means and a second evaluation means. The solar panel includes a plurality of solar cells. The detector layer includes first conductors substantially in parallel in a first plane and second conductors substantially in parallel in a second plane. The second plane is substantially in parallel to the first plane such that the first conductors are at an angle to the second conductors. The first evaluation means is for detecting a failure of one or more of the plurality of solar cells. The second evaluation means is for testing electrical status of the first conductors and the second conductors to determine whether the failure detected by the first evaluation means was caused by a space object damaging or severing one or more of the first conductors and the second conductors.||07-11-2013|
|20130173091||EARLY IDENTIFICATION OF A VORTEX RING PHASE - The invention relates to a method for early detection of the vortex ring state in a helicopter, having the following steps:||07-04-2013|
|20100294893||AERODYNAMIC COMPONENT WITH A DEFORMABLE OUTER SHELL - The invention relates to an aerodynamic component, in particular a wing, a landing flap, a pitch elevator, a yaw rudder, a fin or tail. The aerodynamic component comprises an outer shell and at least one supporting element supporting said outer shell. A drive unit rotates the supporting element. A supporting region is created between the supporting element and the outer shell. The supporting region transfers deformation forces from the drive unit via the supporting element to the outer shell. The supporting element is designed and configured for changing the distance of the supporting region from a longitudinal plane of the aerodynamic component with a rotation of the supporting element. The outer shell comprises an elastic deformation region. The elastic deformation region is elastically deformed by the deformation forces with a rotation of the supporting element.||11-25-2010|
|20100207808||Method for processing TOPS (Terrain Observation by Progressive Scan)-SAR (Synthetic Aperture Radar)-Raw Data - Sub-aperture processing is carried out. Within each sub-aperture, range compression and a correction for the target range variation are carried out. Baseband azimuth scaling is used for processing the azimuth signal, wherein a long azimuth reference function and thus a wide azimuth dimension are prevented. The scaling range is not constant and depends on the range, which is not equal to the original range vector. It is calculated such that, in combination with a subsequent derotation step, constant azimuth scanning is achieved for all ranges. The selected derotation function, which is applied in the azimuth time domain, makes it possible for all the targets to be in base band, in this way varying the effective chirp rate. Since the phase is purely quadratic because of the azimuth scaling step, it is thus possible to use an optimal filter which takes account of the effective chirp rate. IFFT results in a focused image, and a final phase function in the time domain allows phase maintenance. Application for SAR, SONAR and seismic raw data processing in the TOPS mode, as well as other modes which make use of the antenna polar diagram being scanned in the azimuth and/or elevation direction.||08-19-2010|
|20100171651||Method for Examining an Ice Region or Dry Region Using Radar Echo Sounding - To suppress cross-ambiguities in the examination of an ice region or dry region by means of aircraft- or aerospace-supported radar echo sounding, the region to be examined is overflown by a radar sensor (||07-08-2010|

|20090242745||Method for Detecting of Geotectonic Signals Triggered by a Geotectonic Event - For the detection of geotectonic signals triggered by a geotectonic event, an infrasonic wave accompanying the geotectonic event and being generated at the ground and temperature fluctuations are utilized, causing a modulation of an airglow. The modulation of the airglow is detected from the ground by means of an infrared spectrometer and the mesopause temperature is measured with a high temporal resolution. For the detection of a geostationary event, a number of simultaneously operated infrared spectrometers is provided in regions sensitive to geotectonic events.||10-01-2009|
