Estimating the term…
An unmanned aerial vehicle has an internal combustion engine, and a fuel and lubrication system comprising a fuelling system for fuelling the engine and a lubrication system for delivering lubricating oil to the engine. The fuelling system comprises a fuel reservoir from which fuel can be delivered to the engine. The fuel reservoir comprises a main tank and a header tank. The lubrication system comprises an oil tank. The oil tank is accommodated internally within the main tank to provide an integrated assembly. The arrangement provides for warming of lubrication oil for the UAV engine using several available heat sources. Further, the arrangement facilitates a configuration and layout intended to minimise or negate any undesirable moments of inertia for the UAV during flight as fuel and oil is consumed.
A fuel and lubrication system comprising a fuel reservoir and an oil reservoir, wherein the oil reservoir is integrated with the fuel reservoir, and wherein the fuel reservoir comprises a main tank and a supplementary tank which can receive fuel from the main tank and from which fuel can be delivered to an engine.
The fuel and lubrication system according to any one of the preceding claims, wherein the supplementary tank is associated with the main tank, whereby the main tank and the supplementary tank cooperate to provide the fuel reservoir.
The fuel and lubrication system according to any one of the preceding claims, further comprising a transfer system for transferring fuel within the fuel reservoir from the main tank to the supplementary tank.
The fuel and lubrication system according to any one of the preceding claims, wherein the oil reservoir comprises an oil tank accommodated internally within the main tank of the fuel reservoir.
A vehicle having a fuel and lubrication system according to any one of the preceding claims.
A vehicle engine system comprising an internal combustion engine, a fuel system for fuelling the engine, and a lubrication system for delivering lubrication oil to the engine, the fuel system comprising a fuel reservoir, the lubrication system comprising an oil reservoir, wherein the oil reservoir is integrated with the fuel reservoir, and wherein the fuel reservoir comprises a main tank and a supplementary tank which can receive fuel from the main tank and from which fuel can be delivered to the engine.
