The Boundary Layer Ingestion Engine to Aviation Economics
Introduction
Over the past years, aeronautical engineers have been researching how to enhance the
fuel efficiency of aircraft with the aim of saving on fuel costs as well as the improvement of
design sustainability. Some of the current enhancements emphasize the use of lighter materials in
aircraft frames including carbon fiber for the reduction of the amount of thrust essential for
flight. However, these improvements cost more regarding the required materials and are only
responsible for the provision of incremental increases to efficiency. Thus, the adoption of the
boundary layer ingesting (BLI) addresses these issues by increasing the effectiveness of the
design. BLI includes the placement of aircraft turbofans providing thrust into the slower moving
regions of the plane for increasing air pressure intake as well as enhancing propulsive efficiency.
Research on the various novel aircraft concepts focuses on the aspects of performance for the
establishment of the capability of the aircraft to meet developmental goals. Promoting a
sustainable industry requires assessments of economic viability as they are an integral part of the
process of development. Therefore, the main concern is addressing whether high-efficiency
aircraft is responsible for the translation of the concept into the attractive product in the
perspective of economics.
BLI Analysis
There is the great establishment of the theoretical advantages of BLI on promoting
propulsive efficiency, and various frameworks are applicable in analyzing this approach. The
first explanation is that a reduction of the propulsive stream-tube inflow velocity reduces the
amount of power required for imparting on a specific momentum flow to the stream-tube.

Achieving power saving to more than 50% requires a combination of high propulsion disk
loadings and inflow wake profiles. The second concept states that BLI reduces dissipation power
in the flow field through the reduction of stream-wise velocities as well as related misused
kinetic energy the aircraft has left. The benefit of the power balance perspective is its ability to
unify all the power losses that are likely to occur on the plane without resorting to the estimation
of thrust and drag. It has resulted in two primary effects of BLI essential in the study of aviation
economics.
First, it has led to the improvement in propulsive efficiency. Various aspects are essential
in the achievement of best saving: lube, fuel, and cost. Therefore, increasing productivity is the
easiest and fastest way to save. The main components that impacts on propulsion efficiency of
aircraft include engine, hull, and propeller. Maximizing propulsive efficiency requires perfect
integration between the engine and the propeller. Lower kinetic energy flow ingestion gives an
opportunity for the production of propulsive power by the engine thus decreasing dynamic
energy expenditure in exhaust jet contrasted to non-BLI configurations. By increasing fuel
efficiency and reducing cost by up to 10%, BLI can improve the profit levels in the aviation
industry. Secondly, it has resulted in a decrease in the mechanical energy loss of airframe wake.
Through the combination of the propulsive jet and wake, there is a decrease in mixing losses in
jet and wake which causes a reduction in the required power for performing a particular mission.
The aircraft uses little fuel for achieving more results. These benefits have a positive influence
on operation thus increasing income (Budziszewski & Friedrichs, 2018).
