Following an unsuccessful defense of its World Championship titles in 2015, Toyota set itself tough performance targets in order to compete once again at the front of the field, featuring fellow LMP1-Hybrid manufacturers Porsche and Audi. The TS050 HYBRID features a significant change in powertrain concept. A 2.4-liter, twin-turbo, direct injection V6 gasoline engine is combined with an 8MJ hybrid system, both of which are developed by Motor Sport Unit Development Division at Higashi-Fuji Technical Center. The regulations for this season include a reduction in fuel flow and total fuel energy of approximately 7.5%. As motorsport engineers, we want to always increase the performance of the powertrain so it was important to compensate for this reduction with a more efficient, powerful powertrain. We believe a V6, direct injection, twin turbo engine achieves the best balance of power and efficiency considering the current regulations. Combined with our move into the 8MJ class, this will give us significantly improved torque compared to the previous powertrain; this was a key target for the new car. The new powertrain presents some challenges, particularly in terms of weight and cooling, but the team at Higashi-Fuji and Cologne has worked very hard to address these and I am confident we have met the challenge. We face tough opposition, as last year showed, but we are ready and I cannot wait for Silverstone. A new generation turbo engine with direct injection is better suited to the current regulations which limit fuel flow to the engine, and provides opportunity to continue technology and knowledge transfer from the track to road cars. Like Toyota road cars, the front and rear motor-generators recover energy under braking, storing it in a high-powered lithium-ion battery and releasing it as boost for maximum efficiency. The change from super capacitor to battery storage allows the TS050 HYBRID to move up to the more-powerful 8MJ hybrid class. With the engine contributing 368 kW (494 hp) and the hybrid system contributing the same, combined power for the TS050 is 736 kW (987 hp). The TS040 HYBRID was already used as a rolling test bench and contributed to current road cars. With turbo engines increasingly in use on the road, Toyota expects to use the technology and know-how from WEC to make ever-better road cars. The new powertrain concept brings different cooling and packaging demands, including an updated transmission to handle the significant increase in torque delivered by the turbo engine. Combined with a new aerodynamic concept, that means virtually every part on the TS050 HYBRID chassis has been redesigned by Toyota Motorsport GmbH in Cologne, Germany. Powertrain components have played their part too in the improved aerodynamic performance of the TS050 HYBRID—by relocating the front motor-generator unit, better under-floor air flow has been achieved which will contribute to overall performance. Suspension kinematics have also been revised to optimize tire wear. The team has already been busy testing the TS050 HYBRID, striving for performance and reliability, covering over 22,000 km (13,670 miles) with positive results. The next test comes at Paul Ricard on 25-26 March, while the nine-race WEC season kicks off at Silverstone on 17 April. Aside from some principles which have been retained to capitalise on previous years’ development, we have changed every single part. In many areas, like the powertrain and the aerodynamics, the concepts themselves have changed. The aerodynamic concept, and particularly the front face of the car, has changed drastically. We have spent thousands of hours refining this new concept and this time we have done more than incremental changes; we have significantly changed the way we handle the flow structure after the front downforce-generating devices. There has been a significant progress rate in WEC recently so we cannot afford to have any area of the package which is not fully optimized. The TS050 HYBRID has been developed on that basis. We want to be competitive. That is the minimum target we set ourselves—to be back in the game and competitive.
The agency recently wrapped up a comprehensive and successful review of plans for the facilities and ground support systems that will process the agency's Space Launch System (SLS) rocket and Orion spacecraft at NASA's Kennedy Space Center in Florida. "NASA is developing and modernizing the ground systems at Kennedy to safely integrate Orion with SLS, move the vehicle to the pad, and successfully launch it into space," said Bill Hill, deputy associate administrator of NASA's Exploration Systems Development Division at the agency's Headquarters in Washington. "Modernizing the ground systems for our journey to Mars also ensures long-term sustainability and affordability to meet future needs of the multi-use spaceport." Over the course of a few months, engineers and experts across the agency reviewed hundreds of documents as part of a comprehensive assessment. The Ground Systems Development and Operations Program (GSDO), responsible for processing SLS and Orion for flight and ensuring all systems and facilities are ready, completed its critical design review (CDR) of the facilities and ground support systems plans in December 2015. This was followed in January by the completion of an independent assessment by a Standing Review Board, a team of aerospace experts that assessed program readiness and confirmed the program is on track to complete the engineering design and development process on budget and on schedule. In the final step before actual fabrication, installation and testing of Kennedy's ground systems, the GSDO program and review board briefed the results of their assessments to NASA's Agency Program Management Council, led by Associate Administrator Robert Lightfoot. Engineers are transforming Kennedy's launch infrastructure to support the SLS rocket and Orion spacecraft. The heavy-lift rocket will be stacked in the Vehicle Assembly Building on the mobile launcher and roll out to Launch Pad 39B atop a modified crawler transporter. The Orion spacecraft will be fueled with propellants in the Multi-Payload Processing Facility at Kennedy prior to stacking atop the rocket. The launch team will use the new command and control system in the firing room as the clock counts down to liftoff of SLS's first flight. "The team is working hard and we are making remarkable progress transforming our facilities," said Mike Bolger, GSDO Program Manager. "As we are preparing for NASA's journey to Mars, the outstanding team at the Kennedy Space Center is ensuring that we will be ready to receive SLS and Orion flight hardware and process the vehicle for the first flight in 2018." The council also heard the results of the Orion CDR, completed at the program level in October 2015. The evaluation assessed the primary systems of the spacecraft, including the capsule's structures, pyrotechnics, Launch Abort System jettison, guidance, navigation and control and software systems among many other elements. For the spacecraft's first mission on the SLS rocket, ESA (European Space Agency) is providing Orion's service module, which powers, propels, cools and provides consumables like air and water in space. Results from ESA's service module design review, which began this month, will be assessed and incorporated into Orion development and integration plans later this summer. Systems unique to the first crewed flight will be addressed at a review in the fall of 2017. Progress continues on Orion at NASA facilities across the country. The underlying structure of the crew module arrived at Kennedy in early February for outfitting, which is currently underway. Over the next 18 months, thousands of Orion components will arrive and be installed. Meanwhile, a structural representation of the service module is being tested at NASA's Plum Brook Station in Sandusky, Ohio, where engineers conducted a successful solar array wing deployment test on Feb. 29 and are preparing for a variety of tests to confirm it can withstand the harsh conditions of launch.

Well Testing | Year: 2013
Well testing can obtain the dynamic conditions of various geological data and formation parameters, is a kind of effective method to evaluate reservoir and the most direct means. The difficulty from the well test to the development wells especially deep one in Tarim oilfield is faced. Although through the optimization of test method and down-hole tools, some test problems are solved, there are still some shortcomings. Therefore research on well test still needs hard work, to achieve the purpose of safe operation process, reliable test results. Source
