Abstract:
Изобретение относится к авиационной технике, а именно к летательным аппаратам вертикального взлета и посадки. Летательный аппарат вертикального взлета и посадки содержит две турбины, нижняя из которых выполнена тарелкообразной формы, а верхняя - плоской или тарелкообразной формы. Каждая турбина содержит реактивную силовую установку. Каркас каждой турбины установлен на металлическом диске, связанном с вертикальным валом летательного аппарата, и снабжен лопастями. Лопасти установлены с возможностью изменения своего положения. Летательный аппарат может содержать промежуточные турбины, установленные между верхней и нижней турбинами и выполненные плоскими или тарелкообразными. Реактивная силовая установка каждой турбины включает воздушный двигатель и ресиверы, соединенные с компрессором. Каркас каждой турбины выполнен металлическим и включает два кольца, одно из которых соединено с диском, а также радиальные прожилины, установленные по периметру каркаса турбины и соединенные с кольцами и лопастями. Лопасти установлены в один ряд по периметру каркаса или расположены в один ярус. Достигается повышение надежности и экономичности летательного аппарата, возможность его движения вертикально, горизонтально или с любым наклоном.
Abstract:
An aerial vehicle includes a body having a center and a number of spatially separated thrusters. The spatially separated thrusters are statically coupled to the body at locations around the center of the body and are configured to emit thrust along a number of thrust vectors. The thrust vectors have a number of different directions with each thruster configured to emit thrust along a different one of the thrust vectors. One or more of the thrust vectors have a component in a direction toward the center of the body or away from the center of the body.
Abstract:
Embodiments of the invention relate to a vehicle comprising a plurality of inclined rotors that are operable to provide at least one of thrust and torque vectoring according to a desired thrust and/or torque vectors.
Abstract:
The invention relates to an outlet device (4) for a jet engine, the outlet device comprising an outlet nozzle (5) and a plurality of guide vanes (24, 25, 26, 27, 28) arranged movably in the outlet nozzle for guiding a gas from the jet engine for the purpose of steering a craft equipped with the jet engine. At least one of the guide vanes (24, 25, 26, 27, 28) can be adjusted into such a position that hot parts of the engine located inside the outlet nozzle (5) are at least substantially concealed seen from the outlet side (22) of the outlet nozzle.
Abstract:
An engine nozzle arrangement for an aircraft comprises a nozzle (18) for hot exhaust gases, and a shroud (20) for the stream of hot exhaust gases emerging from the exhaust nozzle. The shroud includes means (22, 24) providing an intake for a boundary layer of air for cooling the stream of exhaust gases.
Abstract:
A two-way splitter having reduced distance between outlets, while enabling smooth, efficient fluid flow (e.g., water flow) is provided. In a variant, the splitter includes a first pipe and a second pipe meeting at an interface near the inlet and extending away from the inlet, wherein portions of the first pipe and the second pipe proximal to the inlet are substantially helical and are intertwined with each other. In another variant, the first and second pipes have first portions proximal to the inlet which extend vertically side by side away from the inlet, such that the width of each first portion decreases and the depth of each first portion increases as a vertical distance from the inlet increases.
Abstract:
An embodiment of the present disclosure relates to an unmanned flying robotic object that contains a wheeled mechanism that encircles its spherical exoskeleton. This feature allows the flying spherical vehicle to readily transform into a ground maneuverable vehicle. A robotic motor with differential speed capability is used to operate each wheel to provide effective ground maneuverability. There are examples provided herein of wheel configurations suitable for use with an embodiment. One is the straight- (or parallel) wheel design, and another is tilted-wheel design as are illustrated and discussed hereinafter. One embodiment of an unmanned flying robotic object taught herein is foldable.
Abstract:
The thrust vectoring apparatus comprises: a housing defining a primary outlet for emitting the primary jet; Coanda surfaces extending from opposing regions of said housing, and radially spaced from the primary outlet such that a step is defined between each Coanda surface and the primary outlet; ducts leading from a fluid source to secondary outlets; and flow control means operable to control the mass flow through the secondary outlets. When the jet engine operates to exhaust a primary jet through the primary outlet, low pressure regions are formed in the vicinity of the steps. Each secondary outlet is located adjacent one of the Coanda surfaces so as to emit a secondary flow into a low pressure region. On activation of the secondary flow by the flow control means, the primary jet is entrained by the Coanda surface opposing the Coanda surface adjacent said the secondary outlet from which the secondary flow has been emitted. Method of vectoring the thrust or of upgrading existing jet engines with the thrust vectoring apparatus and jet engines comprising the thrust vectoring apparatus are disclosed
Abstract:
A jet engine nozzle having a pair of pivoting extension arms and a pair of pivoting shells connected to a jet pipe is provided. The first extension arm is pivotally connected to the jet pipe at a first location, while the second extension arm is pivotally connected to the jet pipe at a second location. Each shell is pivotally connected at both the first and second locations. An axis of rotation associated with the first location is coaxial to an axis of rotation associated with the second location. Independent actuation means are provided to rotate the extension arms and the shells, thereby enabling adjustment of the thrust-vector angle or the exhaust area of the nozzle.
