Jettisonable battery systems for powering electrical turbopumps for launch vehicle rocket engine systems
Patent number: 11408374Abstract: Disclosed herein are various technologies pertinent to jettisonable battery systems for use in rocket engine-based launch vehicles. Such systems may feature battery units that are configured to be used to power one or more electric turbopumps that may be used to supply fuel to a rocket engine or engines. One or more of the battery units may be jettisoned during flight in order to reduce weight and as they are depleted. In some implementations, the battery units may be connected in parallel with the turbopump(s), with a depleted battery unit being electrically disconnected from the parallel circuit and jettisoned.Type: GrantFiled: March 27, 2020Date of Patent: August 9, 2022Assignee: Rocket Labs USA, Inc.Inventors: Peter Joseph Beck, Naomi Altman, Jarrod William Burton, Shaun Keith O’Donnell -
Jettisonable battery systems for powering electrical turbopumps for launch vehicle rocket engine systems
Patent number: 11408373Abstract: Disclosed herein are various technologies pertinent to jettisonable battery systems for use in rocket engine-based launch vehicles. Such systems may feature batteries that are configured to be used to power one or more electric turbopumps that may be used to supply fuel to a rocket engine or engines. One or more of the batteries may be jettisoned during flight in order to reduce weight and as they are depleted. In some implementations, a depleted battery may remain electrically connected with the turbopump(s) while a new battery is electrically connected with the turbopump(s). The depleted battery may then be electrically disconnected from the turbopump and jettisoned.Type: GrantFiled: June 24, 2016Date of Patent: August 9, 2022Assignee: Rocket Labs USA, Inc.Inventors: Peter Joseph Beck, Naomi Altman, Jarrod William Burton, Shaun Keith O’Donnell -
Rocket engine turbopump with coolant passage in impeller central hub
Patent number: 11408375Abstract: Disclosed herein are various technologies pertinent to rocket engines, including injector, thrust chamber, and electrical turbopump devices that may be combined to provide a more efficient rocket engine. The electrical turbopump impeller includes a coolant bypass port fluidically connected with a coolant passage that passes through the impeller central hub and allows some of the propellant that is acted on by the impeller to bypass the impeller outlet and instead be flowed into the electrical turbopump housing so that the diverted propellant may be used to cool the various components housed within the housing such as the electric motor bearings, stator, rotor, and electronics.Type: GrantFiled: June 9, 2021Date of Patent: August 9, 2022Assignee: Rocket Labs USA, Inc.Inventors: Peter Joseph Beck, Lachlan Jesse Matchett, Peter William Edward Barlow -

Viscous liquid monopropellant
Patent number: 9970740Abstract: This invention relates to the construction of a rocket motor and fuel system thereof and, in particular to a new and useful Viscous Liquid Monopropellant (VLM) rocket motor containing a liquid propellant that is pumped into the combustion chamber, atomized and then ignited. The atomization step significantly increases the surface area of the propellant, delivering faster burn rates and smoother combustion. VLM is a non-Newtonian fluid containing both oxidizers and fuels. These monopropellants are comprised of a variety of liquid and solid components, mixed together to form a homogenous fluid, although heterogeneous in composition. The solid constituents are retained within the liquid phase by dispersion, suspension, bonding or chemical emulsification techniques, so as when a motive force is applied to the propellant, all the constituents are also transported, and held in correct proportion while doing so.Type: GrantFiled: March 14, 2012Date of Patent: May 15, 2018Assignee: Rocket Lab USA, Inc.Inventors: Peter Joseph Beck, Adam Michael Berry
