The challenges associated with using composites as a replacement for aluminum reside primarily in the complex manufacturing processes and technologies for fabricating composite parts. The high cost of composites material and its manufacturing complexity have been inhibitors to the wide transfer of this technology to the non-aerospace market. The search for solutions to high manufacturing costs and efficient manufacturing processes have resulted in intense research by government, aerospace industry companies, and space agencies worldwide.

The requirements for producing an FAA approved replacement part can be daunting. Understanding the steps required in the FAA Parts Manufacturer Approval (PMA) process can greatly streamline the approval life-cycle and reduce unnecessary costs and delays, thereby shortening the time and cost to market. This course is designed for those organizations and individuals interested in designing and manufacturing replacement parts for civil aviation aircraft. This two-day course covers the crucial subjects and steps of the FAA-PMA approval process.

Crevice Corrosion is one of the most damaging forms of material degradation. Crevice corrosion occurs when a wetted metallic surface is in close proximity to another surface. Almost in any engineered layout there are many instances in which two or more materials are, by design, in close proximity. The primary means of preventing crevice corrosion is careful design. Unfortunately, in most engineering layouts complete avoidance of crevices is not practical. In this study, the corrosion analysis consisted of parts like cast aluminium nipple and a rubber hose clamped over it which were part of the coolant circuit joint of an automobile engine. There was coolant leakage from the joint and bulging of the rubber hose attached to it. A number of failed aluminium nipples were studied for various metallurgical aspects like chemistry, hardness and microstructure and the results were found to be within acceptable limits.

Lubrication system is a critical factor for engine health. But it creates parasitic load and increased fuel consumption of the engine. The oil demand of an engine depends on engine speed, load, bearing clearances, operating temperature and engine's state of wear. Ideally, the oil pump should adapt the delivery volume flow to actual engine oil demand and should avoid unnecessary pumping of oil which causes increased power and fuel consumption. However in a conventional mechanical oil pump, there is no control on the oil flow and it is purely a function of operating speed. A variable discharge oil pump (VDOP) is an approach to reduce the parasitic losses wherein the oil flow is regulated based on the mechanical needs of the engine. This study is based on the results of a two stage VDOP installed on a 1.2L 3 cylinder MPFI engine. The oil supply is regulated by a solenoid control which receives command from Engine control Unit (ECU). The study was done in two stages.

The tractor engine related mounting brackets are very critical due to different aspects of vehicle performance, durability and noise. These mounting bracket have been designed as a framework to support engine external parts like muffler, exhaust tail pipe, fuel filter, alternator etc. Vibration and fatigue has been continuously a concern which may lead to structural failure and performance issues. Various such failures are faced regularly by automotive industry and finite element based analysis are used to resolve them. The resolution is done by playing with the component thicknesses, material, by providing additional support etc. However, due to large degree of uncertainty associated with the loading, boundary conditions, manufacturing, environmental effects; still there is some probability of failure. This paper focuses on a field failure issue of an exhaust system of a tractor and subsequent concern resolution.

AS4726A
This specification establishes the requirements for self-locking nuts, wrenching type (i.e., hexagon, double hexagon, and spline drive), made of a corrosion and heat resistant steel of the type identified under the Unified Numbering System as UNS S66286. Classification: a. 220 ksi minimum tensile strength at room temperature and b. 850 degrees F maximum test temperature of parts. Primarily for use in aerospace propulsion systems in temperatures up to approximately 850 degrees were nuts are used with bolts capable of developing 220 ksi axial tensile strength at room temperature, and having UNJ thread form.

This fluid has been used typically to evaluate the ability of elastomeric and other polymeric compounds to conform to designated requirements after immersion in the fluid at a specific temperature and time, as required by an applicable specification, and its use is limited to such applications. This fluid is not intended for operational use in hydraulic systems. Each application should be considered separately.
