Conceptual design of a fifth generation unmanned strike fighter

Abstract

Unmanned aircraft have significantly transformed aerial warfare through a combination of new technologies, extended operational capabilities, and reduced risks and costs. Similarly, computational modelling techniques have accelerated the rate of development for aircraft by being able to explore a large number of design options from the earliest design stages, further reducing time, risks, and costs. The near future will see the proliferation of unmanned combat aerial vehicles under a variety of roles such as unmanned tankers, strike aircraft, and even air-to-air fighters. In this paper the GENUS aircraft design framework is used to develop an unmanned weapons carrying platform able to partially match the performance of 5 th generation fighters such as the Joint Strike Fighter F-35A. The vision of future joint operations is for a single lead manned fighter to command and designate targets to its various loyal wingmen unmanned aircraft, extending the combat capabilities and significantly multiplying force and air superiority.

Diseño de aeronave de combate no tripulada de quinta generación para el apoyo aéreo cercano

“…También se ha combinado la quinta generación con aeronaves no tripuladas ucav, estas investigaciones incluyen conceptos como el de la inteligencia artificial para así eliminar cualquier dependencia de un piloto (Kong et al, 2020). Adicionalmente, existen propuestas de diseño para aeronaves no tripuladas de quinta generación con la función de caza bombardero (Sepúlveda & Smith, 2019a), e inclusive, se han caracterizado en detalle misiones donde los ucav de quinta generación son destinados a misiones de bombardeo de precisión (Sepúlveda & Smith, 2019b).…”

Numerical investigation of store separation from cavity problems at high speeds

“…The stealth and supercruise capabilities are the main features of the modern military aircrafts. 1 An aircraft with a small radar signature shall, among many other design factors, use a special material for coating and carry all the armament internally. When a stealth aircraft opens its internal/weapon bay to release a store (e.g., bomb or missile), a cavity flow is initiated inside the bay.…”

Aerodynamic design and evaluation of an open-nose supersonic drone

“…In 2012, a concept of a light supersonic drone by Sibylle Walter 7 presented another delta design with a pitot inlet at the nose to create a testbed for academic research such as thrust vectoring and control algorithms at Mach 1.40. A more recent concept of a heavy multirole supersonic drone is proposed by Eduardo Sepulveda 8 (2019) as a 7 ton (empty weight) long range stealthy system with a serpentine inlet configuration which required 93,000 N dry thrust (sea level) in order to supercruise at Mach 1.50 at 9.5 km altitude. The list of operational military unmanned flight systems consists of different types of cruise missiles, target drones, and subsonic reconnaissance and attack systems 9 but no operational supersonic airbreathing drone with the ability for runway take-off and landing.…”
