Automotive Heat Transfer

Heat transfer affects the performance, emissions and durability of the engine as well as the design, packaging, material choice and fatigue life of vehicle components. This course covers the broad range of heat transfer considerations that arise during the design and development of the engine and the vehicle with a primary focus on computational models and experimental validation covering the flow of heat from its origin in the engine cylinders and its transfer via multiple paths through engine components.

FAA/EASA Certification, Methods of Compliance for 29.801 Ditching

Certifying an aircraft, part or appliance can be a challenge. The FAA/EASA procedures can be frustrating and a maze of rules, policy and guidance. Understanding the process and procedures can provide you with a competitive edge and reduce your time obtaining a Certification approval. This course provides an overview of the Federal Aviation Administration (FAA) and European Aviation Safety Agency (EASA) policies, guidelines and requirements leading to Type and Supplemental Type airworthiness approvals. This course has a focus on 29.801 Ditching and EASA 29.802 Emergency Flotation.

Fundamentals of Motor Vehicle Fire Investigation

2021-05-11
The manner in which a motor vehicle fire is initiated and subsequently spreads is dependent on a number of complex, interdependent, phenomena including combustion kinetics, heat transfer and fluid dynamics. Because the damage caused by a fire is coupled to these phenomena, damage patterns can sometimes be used to understand certain characteristics about the fire. In many cases, the goal is to determine the cause and origin of the fire.

Climate Control, 2018

2018-04-03
Climate control is a defining vehicle attribute and is associated with brand image. Thermal performance is critical to customer satisfaction. The primary objective is to deliver occupant safety and thermal comfort at minimum energy consumption, yet the system has strong design interaction with other vehicle systems. Noise, Air Quality, and Energy ace are just a few of the recent advances.

Development of High-Efficiency Rotary Engines

2012-05-10
Combustion engines are typically only 20-30% efficient at part-load operating conditions, resulting in poor fuel economy on average. To address this, LiquidPiston has developed an improved thermodynamics cycle, called the High-Efficiency Hybrid Cycle (HEHC), which optimizes each process (stroke) of the engine operation, with the aim of maximizing fuel efficiency. The cycle consists of: 1) a high compression ratio; 2) constant-volume combustion, and 3) over-expansion. At a modest compression ratio of 18:1, this cycle offers an ideal thermodynamic efficiency of 74%. To embody the HEHC cycle, LiquidPiston has developed two very different rotary engine architectures ? called the ?M? and ?X? engines. These rotary engine architectures offer flexibility in executing the thermodynamics cycle, and also result in a very compact package. In this talk, I will present recent results in the development of the LiquidPiston engines. The company is currently testing 20 and 40 HP versions of the ?M?

Modernizing the Opposed-Piston Engine for Efficient, Clean Transportation

2012-05-10
Historically, the opposed-piston, two-stroke (OP2S) diesel engine set combined records for fuel efficiency and power density that have yet to be met by any other engine type. However, with modern emissions standards, wide-spread development of this engine for on-highway use stopped. At Achates Power, state-of-the-art analytical tools and engineering methods have produced an OP2S engine that, when compared to a leading medium-duty engine, has demonstrated a 21% fuel efficiency gain and engine-out emissions levels meeting U.S. EPA10 with conventional after-treatment. Among the presentation topics covered are thermodynamic efficiency, demonstrated engine results, cost and weight advantages, and overcoming two-stroke engine challenges.

Equivalence of Equipment Environmental Qualification Standards for Civil and Military Aircraft Equipment

2017-10-05
WIP
AIR6811
Provide guidance for applying aircraft equipment electromagnetic, electrical, and mechanical qualification standards, including RTCA/DO-160, MIL-STD-461, MIL-STD-810, and MIL-STD-704, to civil aircraft certification intended for military use and for military aircraft equipment installed on civil aircraft. The guidance will identify where the equipment environmental qualification standards meet the intent of the civil or military aircraft certification requirements. Conversely, the guidance will identify where the equipment environmental qualification standards have differences that do not meet the intent of the civil or military aircraft certification requirements and when these differences matter based on equipment criticality.
