...Jihe Wang; Xibin Cao; Jinxiu Zhang Purpose The purpose of this paper is to propose a fuel‐optimal virtual centre selection method for formation flying maintenance in the J2 perturbed environment. Design/methodology/approach Based on the relative orbital elements (ROE) theory, the J2 perturbed...

...Gilles Labonté Purpose The purpose of this paper is to derive and solve equations for the fuel required by internal combustion engine airplanes on trajectories with a constant rate of climb or descent. Three modes of flight are considered: constant angle of attack, constant speed, and constant...

... it makes less reduction in the primary thrust. It means that for a specific primary thrust, less mass fuel is needed which makes it more economic regarding the traditional SITVC systems. Originality/value The paper's value lies in using a three‐dimensional model to study the effect of two ports...

... Micro-organisms grow in certain fuels using alkanes as a foodstuff or. in some cases, utilising the additives put into the fuel. Aviation fuel is particularly susceptible to micro-organism contamination. It is not uncommon to have micro-organisms in fuel, but if left unchecked and untreated...

... important that the aircraft fuel system is also crashworthy. Traditionally, flexible fuel cells have been employed which were constructed of fabric coated with nitrile rubber, with the emphasis being on constraining the forces involved, particularly in a forced landing. This understandably led to heavy fuel...

...E.M. Goodger Today's jet fuels must adhere to tight specifications. Quality of fuel remains a prime concern. Thermal stability and lubricity are of great importance but pose problems as they tend to be mutually exclusive. Research continues in both areas in the search for improvements. Details...

...J.I. Bates; J.A. Cave Fluids management may be defined as the routeing and confinement of fluids, often under extremes of temperature, pressure and working environment. One of the most critical areas of this technology is the supply and transfer of liquids in aerospace fuel systems. Development...
