“…However, following relevant market research [14,15], it has been determined that the present study will attempt to provide a solution to the increasing future demand for a single aisle passenger aircraft. A BWB design of similar passenger capacity has been developed to compare its performance against an equivalent conventional Airbus A320 aircraft [16]. The design of the present study is set to achieve a range of 3000 nautical miles and to carry a payload weight of 20,000 Kg or 200 people plus baggage.…”

The Blended Wing Body (BWB) configuration is considered to have the potential of providing significant advantages when compared to conventional aircraft designs. At the same time, numerous studies have reported that technical challenges exist in many areas of its design, including stability and control. This study aims to create a novel BWB design to test its flying and handling qualities using an engineering flight simulator and as such, to identify potential design solutions which will enhance its controllability and manoeuvrability characteristics. This aircraft is aimed toward the commercial sector with a range of 3000 nautical miles, carrying 200 passengers. The BWB design was flight tested at an engineering flight simulator to first determine its static stability through a standard commercial mission profile, and then to determine its dynamic stability characteristics through standard dynamic modes. Its flying qualities suggested its stability with a static margin of 8.652% of the mean aerodynamic chord (MAC) and consistent response from the pilot input. In addition, the aircraft achieved a maximum lift-to-drag ratio of 28.1; a maximum range of 4,581 nautical miles; zero-lift drag of 0.005; while meeting all the requirements of the dynamic modes.

“…The BWB Aircraft is more susceptible to turbulent airflows due to the lack of a vertical tail. Sami Ammar et al [22] therefore performed a stability analysis on a 200 passenger self-designed BWB and compares the results to an equivalent conventional A320 and B747 airbus. CEASIOM a designing platform was used for conceptualizing the BWB under parameters like drag and engine performance.…”

Over multiple iterations spanning many years of research a stable and aerodynamically workable fuselage structure has been zeroed down on. The fuselage being the segment holding the passengers and crew requires an immaculate degree of stability during takeoff, landing and flight. Aerodynamic optimisation presupposes every notion of this 'in flight stability'. The recent interest taken in the field of stability under unforeseen air conditions has led to remarkable developments in the field of aerodynamics. This paper attempts to categorically classify these interests into 3 sections-Theoretical, Experimental and Numerical. Various mathematical models and algorithms have been created to study and test the stability of the fuselage under turbulent conditions caused by weather. Turbulence caused by on flight equipment (propellers etc) and methods for its mitigation have also been mentioned. The chine angle analysis of the fuselage reveals that a sharper angle is more favorable in increasing the lift. The study of asymmetrical vortices and its evolution has enhanced the field of aerodynamic optimization. Unconventional aircraft designs like the BWB are studied and compared against the incumbent structures. Various modeling softwares like CATIA have extensively been used to design these structures. A compilation of these recent developments has been presented to those attempting to intensively analyse and study the field of aerodynamic stability.

“…Engine installation on conventional transport is often mounted under the wing (Oliveira, Trapp, & Puppin-Macedo, 2003;Stankowski, MacManus, Robinson, & Sheaf, 2017). However, the engine of BWB is usually located over its center body (Ammar, Legros, & Trépanier, 2017;Plumley & Zeune, 2017). Positioning the engine over the center-body may distort its lift distribution, thus creating poor cruise aerodynamic (Okonkwo & Smith, 2016).…”

The difference of the aerodynamic influence of two engine models -the Flow Through Nacelle (FTN) and With Powered Nacelle (WPN) -on BWB300 airframe is analyzed by using the 3-D unsteady compressible Reynolds-Averaged Navier-Stokes (RANS) computation. The results indicate that at cruise condition, the engine shape is a primary factor affecting the BWB airframe upper fuselage surface flow, the two engine models exhibit a similar aerodynamic influence on the BWB airframe. However, at takeoff condition, the two engine models' aerodynamic influence on the airframe is different, because of the air suction caused by the WPN engine model affecting the airframe upper fuselage surface flow obviously. Moreover, at both cruise and takeoff conditions, the tube formed by the engine and airframe shape changes the surface flow under the engine and the air suction caused by the engine power accelerates the surface flow near the engine.
