Patent number: 11685517Abstract: Installation of powered actuators in the leading edge of a control surface in order to have a better weight distribution. The systems described herein propose an actuation system with a static ground structure used to move a control surface of an aircraft. The actuation system, and the ground structure are aligned with the center of rotation of the control surface, providing the aircraft with flutter suppression. This proposal is an approach to use the actuator in a place favorable to the mass balancing and reducing or even dismissing the usage of mass balancing, saving weight and cost.Type: GrantFiled: August 11, 2021Date of Patent: June 27, 2023Assignee: Embraer S.A.Inventors: Marcelo Galväo, Rodolfo de Souza Martins

Patent number: 11624396Abstract: Seal cap devices are provided as an integral (one-piece) structure comprising an open-ended cylindrical body member sized so as to surround a threaded shaft of a fastener, the body member including an upper wall having (i) an arcuate interior edge which defines an aperture to allow threaded engagement with distalmost threads of the threaded shaft of the fastener, and (ii) at least one slot radially extending from the aperture. The upper wall may include opposed slots radially extending from the aperture, e.g., a pair of opposed slots radially extending from the aperture that are separated from one another by an angle of about 90°. A sealant material within the cap may therefore envelope the threaded shaft of the fastener and any collar nut associated therewith to provide a reliable seal.Type: GrantFiled: October 20, 2017Date of Patent: April 11, 2023Assignee: EMBRAER S.A.Inventor: Sérgio Pegurier

Patent number: 11623757Abstract: For aircraft taxiing, an aircraft is equipped with an electric machine installed in a propulsor gearbox (PGB), in parallel to the gas turbine, working in motor mode during taxi, and in generator mode during flight phases (such as take-off, climb, cruise, descent, approach and landing). Typical current systems which use an electric machine in the PGB do not use the electric machine in motor mode for taxi operations (i.e., it is only an additional generator). An optimized power supply providing a combination of a thermal engine such as an Auxiliary Power Unit (APU) and an electric energy storage system such as a battery provides power to the PGB electric machine even when the gas turbine is off.Type: GrantFiled: June 7, 2019Date of Patent: April 11, 2023Assignee: Embraer S.A.Inventors: Raphael Felipe Gama Ribeiro, Francisco Palazzo Neto

Patent number: 11597514Abstract: Unmanned aircraft have aligned forward and aft propulsion systems possessing different performance and/or noise characteristics. According to some embodiments, unmanned aircraft have a forward engine and a forward tractor propeller and an aft engine and an aft pusher propeller. Selected ones of forward and aft propulsion systems will thus be provided to have greater and lesser operational flight performance characteristics and greater and lesser noise signature characteristics, respectively, as compared to the other. For example, the forward propulsion system may be provided with the greater operational flight performance and higher signature characteristics as compared to the aft propulsion system, while conversely the aft propulsion system may be provided with a lesser flight performance and lower noise signature characteristics as compared to the forward propulsion system.Type: GrantFiled: August 16, 2019Date of Patent: March 7, 2023Assignee: EMBRAER S.A.Inventors: Raphael Felipe Gama Ribeiro, Tarik Hadura Orra

Patent number: 11382547Abstract: A system and method provides noninvasive mental state diagnostics and brain stimulation via consensual transcranial stimulation. The method utilizes face recognition associated with known physiologic measures to identify an emotional state-of-mind of a human subject and then provides or at least suggests a transcranial stimulation treatment for enhancing mental focus or for alleviating discomfort or anxiety by inducing a feeling of well-being. An example system arrangement utilizes a camera to scan a subject's facial expressions and, if the subject desires, provides a transcranial stimulation to the subject based upon an analysis of the facial expression. In one example environment, the system is used in the office or other workplace. In another example environment, the system is used in conjunction with a vehicle seat, such as for example a seat in a car, train, aircraft or other vehicle.Type: GrantFiled: September 12, 2016Date of Patent: July 12, 2022Assignee: Embraer S.A.Inventors: Paulo Anchieta Da Silva, Flavia Renata Dantas Alves Silva Ciaccia
