Enhancing Sustainable Aviation through Contrail Management – A Framework for Multiple Platforms

Effective contrail management while ensuring operational and economic efficiencies for flight services is essential for providing services with minimal adverse environmental impact. The paper explores various aspects of contrail management applicable to different platforms such as Unmanned vehicles, Commercial airliners and Business & regional jets. The aspects unique to each platform such as flight levels of operation, fuel types, flight endurance and radius of operation have been analyzed. Expanse of 5G network is resulting in increased flight activity at flight levels not envisaged hitherto. The paper also dwells on the ramifications of the increased proliferation of different platforms at newer flight levels from the perspective of contrail management.

Sustainable Microalgae-Membrane Photobioreactor (MPBR) System for Onboard Oxygen Production in an Aircraft

The purpose of the Air Generation System is to provide a constant supply of conditioned fresh air to meet the necessary oxygen availability and to prevent carbon dioxide (CO2) concentrations for the occupants in an aircraft. The engine bleed energy or electrical load energy consumed towards this circumstance accounts to be approx. 5% of total fuel burn and in turn, contributes to the global emissions of greenhouse gases. This paper studies the improvement areas of the present conventional system such as fuel burn consumption associated with an aircraft environmental control system (ECS) depending on, the amount of bleed and ram air usage, electric power consumption. Improved systems for propulsion, power generation, sustainability, hybridization, and environmental control can be desirable for an aircraft.

Development of the Smallest & Lightest 60A Aerospace Contactor

Electromechanical Power Contactors are widely used in the Power Distribution units of large commercial & military aircrafts to control the different power sources. In aerospace applications the SWaP (size, weight, and power consumption) is very important since the available space is limited, the weight contributes to higher fuel consumption along with the requirement of high-power electrical sources for catering the high-power requirements. Since more than 100 contactors are used in a single aircraft even a small saving in SWaP leads to huge benefits. Managing the SWaP constraints along with the Harsh environmental and thermal requirements associated with Aerospace applications is a major bottleneck for futuristic aerospace transportation.
