Method and System to Control Operation of a Device Using an Integrated Simulation with a Time Shift Option

Abstract: A method to control a device may include forming an integrated simulation model of an actual environment in which the device is or will be operating The integrated simulation model may be formed using pre-existing data and real-time data related to the actual environment The method may also include presenting a simulation including a representation of the device operable in the integrated simulation model of the actual environment and allowing control of operation of the simulation of the device in the integrated simulation model of the actual environment The method may further include controlling operation of the device in the actual environment using the simulation of the representation of the device in the integrated simulation model of the actual environment

Advanced Subsonic Airplane Design and Economic Studies

Abstract: A study was made to examine the effect of advanced technology engines on the performance of subsonic airplanes and provide a vision of the potential which these advanced engines offered. The year 2005 was selected as the entry-into-service (EIS) date for engine/airframe combination. A set of four airplane classes (passenger and design range combinations) that were envisioned to span the needs for the 2005 EIS period were defined. The airframes for all classes were designed and sized using 2005 EIS advanced technology. Two airplanes were designed and sized for each class: one using current technology (1995) engines to provide a baseline, and one using advanced technology (2005) engines. The resulting engine/airframe combinations were compared and evaluated on the basis on sensitivity to basic engine performance parameters (e.g. SFC and engine weight) as well as DOC+I. The advanced technology engines provided significant reductions in fuel burn, weight, and wing area. Average values were as follows: reduction in fuel burn = 18%, reduction in wing area = 7%, and reduction in TOGW = 9%. Average DOC+I reduction was 3.5% using the pricing model based on payload-range index and 5% using the pricing model based on airframe weight. Noise and emissions were not considered.

A ramp system

Abstract: A ramp system (10) in a first embodiment incorporates a fore (12) and an aft (14) ramp section interconnected by a spindle (24) which permits both pitch and roll movement of the aft section relative to the fore section. The fore section is hingedly connected to an aircraft structure at an opening thereof so that the fore section is capable of pitch movement relative to the aircraft. A set of hydraulic actuators (22) provide controlled movement to the sections and additionally secure the sections in their desired positions. A set of rollers (26) and curved tracks (28) on adjoining portions of the sections both provide secure interconnection of the sections and prevent yaw movement of the aft section relative to the fore section. Rotation of the aft section relative to the fore section allows quick and simple disconnection and removal of the aft section and thereby provides interchangeability with alternate aft sections adapted to provide the aircraft with alternate functional capabilities. The second embodiment (110) is essentially similar to the first embodiment except that it utilizes a ramp (114) which is directly connected to an aircraft structure (116) via the spindle (124) and set of rollers (126) and tracks (128) so that the ramp (114) is removable from the aircraft structure (116) and interchangeable with other ramps.

Environmentally Responsible Aviation (ERA) Project - N+2 Advanced Vehicle Concepts Study and Conceptual Design of Subscale Test Vehicle (STV) Final Report

Abstract: NASA has set demanding goals for technology developments to meet national needs to improve fuel efficiency concurrent with improving the environment to enable air transportation growth. A figure shows NASA's subsonic transport system metrics. The results of Boeing ERA N+2 Advanced Vehicle Concept Study show that the Blended Wing Body (BWB) vehicle, with ultra high bypass propulsion systems have the potential to meet the combined NASA ERA N+2 goals. This study had 3 main activities. 1) The development of an advanced vehicle concepts that can meet the NASA system level metrics. 2) Identification of key enabling technologies and the development of technology roadmaps and maturation plans. 3) The development of a subscale test vehicle that can demonstrate and mature the key enabling technologies needed to meet the NASA system level metrics. Technology maturation plans are presented and include key performance parameters and technical performance measures. The plans describe the risks that will be reduced with technology development and the expected progression of technical maturity.

Rotor blade for a wind power plant

Abstract: The invention concerns a rotor blade of a wind power installation and a wind power installation. One advantage of the present invention is to provide a rotor blade having a rotor blade profile, and a wind power installation, which has better efficiency than hitherto. A rotor blade of a wind power installation, wherein the rotor blade has a thickness reserve approximately in the range of between 15% and 40%, preferably in the range of between about 23% and 28%, and wherein the greatest profile thickness is between about 20% and 45%, preferably between about 32% and 36%.

Subsonic Ultra Green Aircraft Research

Abstract: This report summarizes the Truss Braced Wing (TBW) work accomplished by the Boeing Subsonic Ultra Green Aircraft Research (SUGAR) team, consisting of Boeing Research and Technology, Boeing Commercial Airplanes, General Electric, Georgia Tech, Virginia Tech, NextGen Aeronautics, and Microcraft. A multi-disciplinary optimization (MDO) environment defined the geometry that was further refined for the updated SUGAR High TBW configuration. Airfoil shapes were tested in the NASA TCT facility, and an aeroelastic model was tested in the NASA TDT facility. Flutter suppression was successfully demonstrated using control laws derived from test system ID data and analysis models. Aeroelastic impacts for the TBW design are manageable and smaller than assumed in Phase I. Flutter analysis of TBW designs need to include pre-load and large displacement non-linear effects to obtain a reasonable match to test data. With the updated performance and sizing, fuel burn and energy use is reduced by 54% compared to the SUGAR Free current technology Baseline (Goal 60%). Use of the unducted fan version of the engine reduces fuel burn and energy by 56% compared to the Baseline. Technology development roadmaps were updated, and an airport compatibility analysis established feasibility of a folding wing aircraft at existing airports.
