Driving with Grid Energy - The Chevrolet Volt Extended Range EV

2011-11-04
With the introduction of the Chevrolet Volt, the Electrification of the Automobile begins in earnest, by offering a car that runs off of grid energy that has mass market appeal. The Volt offers a vehicle which is driven primarily by electricity under ?real world? driving conditions, while not presenting the driver with inconvenient choices about range and recharge time, or the disconcerting experience of a real possibility of becoming stranded. The Voltec powertrain arrangement enables the Volt to be an Extended Range Electric Vehicle, or E-REV and gives full performance utilizing only electrical energy from the grid for most driving, and a seamless transition to gasoline energy for longer and less frequent trips to maintain full vehicle utility. General Motors and its suppliers has had to the lead developments of fundamental component technologies that were not addressed by earlier, more simple hybridization work.

Fiber Optic Strain Sensor Standardization - International and European Activities

2012-03-16
There are worldwide activities in developing guidelines and standards for fiber optic sensors. Fiber optic sensors (FOS) are increasingly demanded for structural health monitoring purposes and for measurement of physical and chemical quantities because of their specific features. However, they are not yet widely established for practical use due to a lack of guidelines and confirmed standards. Therefore, there are few groups worldwide which are very active in developing standards for use of FOS in different fields, particularly driven from aircraft industry, oil industry or the necessity to provide sensor systems for health monitoring of structures with a certain level of risk. The benefits of guidelines and/or standards on the way to well-validated and well-specified sensor systems will be presented by means of related examples. The presentation will also give an overview on the state-of-the-art and most relevant activities. Results achieved are discussed.

What If We Let Consumers Design PHEVs?

2011-11-04
Consumers design different PHEVs than expert analysts assume. Experts almost uniformly assume PHEVs that offer true all-electric driving for 10 to 60 miles; consumers are more likely to design PHEVs that do not offer true all-electric driving and have short ranges over which they use grid-electricity. Thus consumers? PHEV designs are less expensive. These consumer PHEV designs do, or don?t, produce lower GHG emissions than experts? PHEVs over the next ten years. The devil is in the details, i.e., which powerplant emissions to assign to new electricity demand: marginal or average. If (based on marginal powerplant emissions) it makes almost no difference whether we sell consumer-designed or expert-assumed PHEVs over the next ten years, yet as the grid continues to de-carbonize all-electric PHEV designs emerge as clearly the better option, there is a trajectory we could be on from blended, ?short range? PHEVs to all-electric ?long range? PHEVs.

Beyond MPG: Characterizing and Conveying the Efficiency of Advanced Plug-In Vehicles 

2011-11-08
Research in plug in vehicles (PHEV and BEV) has of course been ongoing for decades, however now that these vehicles are finally being produced for a mass market an intense focus over the last few years has been given to proper evaluation techniques and standard information to effectively convey efficiency information to potential consumers. The first challenge is the development of suitable test procedures. Thanks to many contributions from SAE members, these test procedures have been developed for PHEVs (SAE J1711 now available) and are under development for BEVs (SAE J1634 available later this year). A bigger challenge, however, is taking the outputs of these test results and dealing with the issue of off-board electrical energy consumption in the context of decades-long consumer understanding of MPG as the chief figure of merit for vehicle efficiency.

Study of Materials and Coatings Used for Drilling Carbon Fiber Re-inforced Plastics

2012-03-14
With the increased usage of Carbon Fiber Reinforced Plastics (CFRP) in the aircraft industry, there has been increased pressure to improve cutting tool life. Tungsten carbide tools were the first to be applied to CFRP materials. Poly Crystalline Diamond (PCD) tools also became an acceptable material to be used as a cutting tool material. In recent years, Chemical Vapor Deposition (CVD) diamond tools have become more popular as a cutting tool material for CFRP. This study compares these possible cutting tool materials in the drilling of CFRP. Wear is measured as well as hole quality. Life is determined by common industry standards with regard to fiber break out in a common CFRP material. An economic analysis is conducted in order to determine cost per hole.

Vertical Picture-Frame Wing Jig Structure Design with an Eye to Foundation Loading

2012-03-14
The foundation of many production aircraft assembly facilities is a more dynamic and unpredictable quantity than we would sometimes care to admit. Any tooling structures constructed on these floors, no matter how thoroughly analyzed or well understood, are at the mercy of settling and shifting concrete, which can cause very lengthy and costly periodic re-certification and adjustment procedures. It is with this in mind, then, that we explore the design possibilities for one such structure to be built in Belfast, North Ireland for the assembly of the Shorts C-Series aircraft wings. We evaluate the peak floor pressure, weight, gravity deflection, drilling deflection, and thermal deflection of four promising structures and discover that carefully designed pivot points and tension members can offer significant benefits in some areas.

Safety and Operational Improvements Using Head-Up Displays in Small Aircraft and Helicopters

2012-03-12
Small aircraft and helicopters have an increasing need for heads out presentations, which means a projected presentation of symbols and images, primarily infrared, on an optical combiner in the pilots field of view. The information presented will appear at an infinite distance i.e. the focal point is far away enabling the pilot to see the symbology superimposed on and correlated to the outside world. The driving factors for a heads out presentations are increased safety through improved situation awareness in almost all weather conditions as well as operational improvements due to reduced landing minimal prerequisites in adverse weather conditions. Also safety during taxiing and landing are improved through early detection of eventual other aircraft and objects. The landing aid is important for small aircraft like business jets that often fly into unequipped airfields. The overall benefits are reduction in number of incidents/accidents, cost savings and reduced number of diversions.

Sensor Video Integration and Processing in the Modular Avionics Architecture

2012-03-19
Use of airborne high resolution digital sensor imagery is ever increasing. Color HDTV, infrared cameras and radar are examples of such sensors. And they are becoming increasingly used for mission purposes by the military, police, customs and coast guard onboard helicopters and fixed wing aircraft. These users have requirements for onboard presentation, analysis and storage. Use of weather radars and other similar types of sensors are flight oriented applications in major types of aircraft. Another application is the integration of cockpit and cabin surveillance systems onboard commercial airlines. Cabin surveillance systems, growing from cockpit door cameras to complete cabin surveillance, will use several cameras. The purpose is to acquire and store imagery from un-normal events including unruly passengers and eventual terrorists. The primary intentions are security awareness in the cockpit as well as collecting evidence for a potential prosecution.

Ice Phobic Coatings for Control and Covered Surfaces

2012-03-14
Silicones have been utilized in multiple industries in the last 50 years and their applications are still expanding as technology grows. Ice phobic coatings, as an example, have been utilized on lock walls, navigation channels, wind turbines, hydropower intakes, and aircraft. Without protection these applications have a high risk of failure in the functions they perform. For example, ice build up on an aircraft?s aerodynamic surfaces increases drag which reduces lift during flight operations. Utilizing a silicone ice phobic coating significantly reduces the adhesion of ice to aerodynamic surfaces. Compared to other polymeric materials, silicones are known for their broad operating temperature range and lend themselves to excellent performance in a variety of harsh environments. Especially in low temperatures where ice adhesion is a concern, silicones retain their elastomeric physical properties and low modulus.

Comparison of Powertrain Configuration Options for Plug-in HEVs from a Fuel Economy Perspective

2012-05-25
The first commercially available plug-in hybrid electric vehicle (PHEV), the General Motors (GM) Volt, was introduced into the market in mid-December 2010. The Volt uses a series-split powertrain architecture, which provides benefits over the series architecture that typically has been considered for use in electric-range extended vehicles (EREVs). A specialized EREV powertrain, called the Voltec, drives the Volt through its entire range of speed and acceleration with battery power alone and within the limit of battery energy, thereby displacing more fuel with electricity than a PHEV, which characteristically blends electric and engine power together during driving. This paper assesses the benefits and drawbacks of these two different plug-in hybrid electric architectures (series versus series-split) by comparing component sizes, system efficiency, and fuel consumption over urban and highway drive cycles.
