Blazing a Sustainable Trail in Aviation: Introducing SAF
The aviation industry stands at the forefront of addressing climate change, striving to meet ambitious carbon neutrality goals by 2050. A critical element in this transformation is the adoption of Sustainable Aviation Fuel (SAF), a cleaner alternative to conventional jet fuel. Over the years, flight and ground tests using both blended and unblended SAF have demonstrated its potential to reshape aviation’s environmental footprint.

Sustainable Aviation Fuel is essential to the future of the aerospace industry, as it offers the opportunity to continue to build that industry with relatively few changes required in their entire regime – which one would have to agree is indeed very complex. The key difference here is that SAF fuel generally no longer comes from the petroleum industry but rather from the biomass industry.
SAF and Hydrogen Fuel Applications in Aerospace – Part 2
Airbus aims to bring to market the world’s first hydrogen-powered commercial aircraft by 2035. To achieve this, they have proposed the ZEROe project, which will explore a variety of configurations and technologies and prepare the ecosystem that will produce and supply the needed hydrogen. Airbus’ ZEROe program will use four original concepts.
SAF and Hydrogen Fuel Cell Applications in Aerospace – Part 1
ZeroAvia’s fuel cell power generation system technology will be used to demonstrate the concept of using a fuel cell variant in an amphibious flying boat design.
They have selected the PHA-ZE 100 composite amphibious aircraft to demo this project.

The price points for the BWB demonstrators are higher, while revenues are not yet evident. Two projects are part of this story. The first is the US government’s support for a demonstrator project for the Blended Wing Body. The second project is the EcoJet Business Jet, being proposed by Bombardier.

An example of Multi-Functional Structures would be antennas embedded in the fuselage. These items would, for example, reduce the weight of both items by being combined meaningfully during manufacture. One item provides structural support, while the other supports systems integration.

The hybrid or blended wing body demonstrator represents a new approach to designing aircraft. Traditional models of aircraft design have used a tube and wing layout. That design is now being considered for replacement by the hybrid or the blended wing body.

An important point about FBW is that the loss of all flight control computers immediately renders the aircraft uncontrollable. Backups are necessary to compensate for such events. Most fly-by-wire systems incorporate redundant computers. Furthermore, mechanical and hydraulic backups sometimes provide the needed redundancy.
CAPSTONE Project 2023: Prepare Manufacture-Ready Transport and Storage Cart
The team employed analytical and numerical methodologies to assess the design against the customer-defined requirements, including static and fatigue studies of the structure and its associated components. The team also provided procurement specifications for the off-the-shelf components, as well as detailed manufacturing specifications for those parts requiring manufacturing.

Three approaches for reducing the in-flight energy requirements of aircraft are discussed. These ideas consider deploying composites, creating higher gas turbine power densities, and building gas turbine engines with low NOx combustion gasses.
