Patent number: 11982250Abstract: A rocket engine comprising a rotating detonation rocket engine and three propellants. The propellants comprise of at least one of an oxidizer and at least one fuel. A third propellant, a fuel, oxidizer or inert fluid, may be injected to control the detonation characteristics. The rocket engine may further include wan additional rocket engine wherein a pump provides pressure for multiple engines. The rocket engine may further include multiple turbopump shafts for independent control of the propellants.Type: GrantFiled: December 23, 2021Date of Patent: May 14, 2024Assignee: Venus Aerospace Corp.Inventor: Andrew Thomas Duggleby

Patent number: 11970995Abstract: A rocket engine system having a heating system configured to heat an oxidizer; a combustion section having a flow path from an upstream inlet section through a restricted throat section to a downstream outlet section, the combustion section configured to accelerate the heated oxidizer as an oxidizer stream within the flow path in response to flow dynamics to supersonic speed; and a fuel system configured to introduce a fuel into the flow path to mix supersonically with the heated oxidizer to define a combined fuel and oxidizer stream at a first supersonic speed. The combined fuel and oxidizer stream undergoes a deflagration to denotation transition in the combustion section defined by an oblique shock wave and a normal shock wave that interact to achieve a standing detonation wave generally at an upstream portion of the restricted throat section configured such that combustion exits the downstream outlet section to provide thrust.Type: GrantFiled: May 31, 2022Date of Patent: April 30, 2024Assignee: Venus Aerospace Corp.Inventor: Andrew Thomas Duggleby

Patent number: 11911754Abstract: Disclosed is a method for forming a catalyst bed for catalytic decomposition of hydrogen peroxide, which uses 3-D printing techniques to form a porous metal backbone and treating the surface of the metal backbone to activate the surface, wherein the metal backbone is formed of a noble metal or a manganese complex. Also disclosed is a rocket engine having a 3D printed catalyst for catalytic decomposition of hydrogen peroxide, a fuel store, an oxidizer store, and a rocket engine, wherein the oxidizer is a stabilized solution of hydrogen peroxide, and a 3D printed catalyst bed.Type: GrantFiled: January 10, 2023Date of Patent: February 27, 2024Assignee: VENUS AEROSPACE CORPInventors: Aubrey Michael Yates, Nicholas D. Cardwell

Patent number: 11840988Abstract: A rocket engine system including a coolant source containing a coolant fuel. The coolant source for providing the coolant fuel to a first surface of a wall partially defining a combustion chamber of a rocket engine, and the coolant fuel provides film cooling of the first surface of the wall. An oxidizer source for providing an oxidizer to a second surface of the wall. A monitor configured to control flow of the coolant fuel and the oxidizer, and to ensure that a stoichiometry of a combination of the coolant fuel and the oxidizer, after the coolant fuel has completed the film cooling of the first surface of the wall, is appropriate for generating a combustion of the combination of the coolant fuel and the oxidizer.Type: GrantFiled: March 3, 2023Date of Patent: December 12, 2023Assignee: Venus Aerospace Corp.Inventor: Aaron Ezekiel Smith
