Future Aircraft Fuel Efficiencies
A review has been performed of the current method of forecasting CO2 emissions fromaircraft using UK airports. The current approach uses the CORINAIR Guidebook data tocalculate the fuel burn by individual aircraft on each route. The assessment has coveredthe mapping of aircraft types to those in CORINAIR, the accuracy of the data (bycomparison with data from the AERO2k greenhous...
متن کاملLocomotory energetics and metabolic fuel reserves of the Virginia opossum.
Marsupials have lower resting metabolic rates than placental mammals, but it is not clear whether particular species can extend this energetic advantage to locomotion. Some active marsupials have a low cost of locomotion, but other more sedentary species, such as the Virginia opossum, appear to run very inefficiently. Steady-state rates of O2 consumption (VO2) and CO2 production (VCO2) were mea...
متن کاملCan “stranded” fossil fuel reserves drive CCS deployment?
Recent studies have evaluated the climate change implications of burning all of the world’s proven reserves of carbon. To stay below the ambitious target of two degrees Celsius of warming above average pre-industrial temperatures, the International Energy Agency (IEA) estimates that we would need to emit no more than 884 GtCO2 globally between 2012 and 2050, equivalent to burning approximately ...
متن کاملScheduling of Arrival Aircraft Based on Minimum Fuel Burn Descents
The main goal of this research is to investigate minimum fuel descent trajectories for various types of aircraft and consider appropriate arrival sequencing based on the acquired results. First, the validity of a point mass model to find optimized descent trajectories in order to obtain minimal fuel consumption is confirmed. Through single aircraft numerical simulations, the principle “higher f...
متن کاملStatistical Modeling of Aircraft Engine Fuel Flow Rate
Knowledge of the fuel flow rate is important for accurate fuel burn and emissions inventory generation and for accurate engine performance modeling. In this paper, machine learning techniques are applied to aircraft flight recorder data to model the fuel flow rate as a function of the aircraft altitude, ground speed, vertical speed, and takeoff mass in the airborne phases of flight. Models are ...
