3D Cruise Trajectory Optimization Inspired by a Shortest Path Algorithm

Abstract: Aircrafts require a large amount of fuel in order to generate enough power to perform a flight. That consumption causes the emission of polluting particles such as carbon dioxide, which is implicated in global warming. This paper proposes an algorithm which can provide the 3D reference trajectory that minimizes the flight costs and the fuel consumption. The proposed algorithm was conceived using the Floyd–Warshall methodology as a reference. Weather was taken into account by using forecasts provided by Weather… Show more

“…Kawser et al (2020) used the shortest path algorithm to create the ideal flight trajectory. Mendoza et al (2020) proposed a model that minimizes flight costs and fuel consumption and provides an alternative route using the Floyd–Warshall methodology. Liu et al (2021) explored potential ways to increase the fuel efficiency of flight operations.…”

“…We consider these variables because they are input variables for SOPHIA and included in GFS data, and it is a known fact that temperature and wind are crucial for trajectory optimization. The ground speed (m/s), i.e., the speed of an aircraft relative to the ground, can be calculated [21] with (m/s); V T is the true airspeed (m/s) relative to the still air; Z Wind and Z Temp are the wind vector and temperature (K); Mach denotes the Mach number, the vehicle airspeed relative to the speed of sound at current atmosphere condition; and k and R are constant for heat capacity ratio and gas constant, respectively. From this equation, we can see the importance of temperature and wind on the key parameters describing the status of an aircraft.…”

“…Consequently, the approach needs to account for trajectory optimization. Typically, aircraft trajectory optimizations minimize cruise fuel consumption but they can also be used to improve data collection [12], search efficiency [13], energy efficiency [14], fuel consumption [15] or environmental impact [16]. This work focuses on a single multi-segment trajectory optimization considering take-off, climb and cruise portions while respecting the flight path continuity.…”
