Design of The VTOL Jet Engine for Energy Efficiency and Lightweight Flying Vehicle Analysis in Malaysia

Driven by the growing demand for efficient emergency Vertical Takeoff and Landing (VTOL) transportation and advanced air mobility, the development of lightweight flying vehicles has become increasingly critical. This research presents an innovative flap design integrated with a jet engine system to optimize the aerodynamic efficiency and flight endurance of a lightweight aircraft. Characterized by a 770 kg payload capacity and a maximum speed of 425 km/h, the proposed vehicle underwent a rigorous development process involving aerodynamic analysis, structural configuration design, Computational Fluid Dynamics (CFD) simulations, and validation. The airframe leverages high-strength, lightweight materials specifically carbon fiber and aluminum integrated with a jet propulsion layout to reduce energy consumption. Numerical simulations demonstrate that the proposed flap configuration enhances flight endurance by approximately 36% over conventional designs. This framework exhibits strong potential for emergency response applications, including ambulatory and rescue operations, by mitigating traffic-induced delays. This study contributes directly to the advancement of energy-efficient jet engine technology and next-generation aerospace transportation systems in Malaysia.
