摘要:
Described herein are various apparatuses, methods, and computer program products for providing a carbon-footprint modeling environment that determines a consumer's carbon footprint based on the consumer's acquisition of goods and/or services, as indicated by the consumer's transaction data. For example, the carbon-footprint modeling environment collects the consumer's transaction data for a predefined period of time and identifies transaction data that indicates the consumer's acquisition of goods and/or services that, when produced and/or consumed, result in greenhouse gas emissions. According to some embodiments, the carbon-footprint modeling environment categorizes goods and/or services into, for example, the following categories: transportation, housing, food, waste, and miscellaneous. Based on information gleaned from the consumer's transaction data, the modeling environment may determine the quantities of goods and services the consumer consumed in each of the categories and then apply conversion ratios to convert the respective quantities of goods and/or services consumed into units of greenhouse gas emissions.

摘要:
A liquid propelled rocket engine comprising a unique pintle injector, radial injector plate and ablative insert to improve combustion stability and reduce harmonic disturbance within the chamber. The injector plate is generally in the shape of a ring surrounding a combination spud and pintle injector, the two allowing at least one liquid propellant and one liquid oxidizer to be injected into the chamber. The injector plate has an array of injectors for injecting liquid propellant into the chamber and a series of cavities within allowing the harmonic disturbance to be damped and providing a more stable combustion environment. The number of cavities and the unique pintle injector's length and width are chosen to reduce harmonic disturbance in the longitudinal, radial and lateral modes. A method for designing engine components and tuning harmonic frequencies within a combustion chamber is also disclosed.
