NASA is conducting a study to determine if more environmentally friendly aircraft fuels can reduce the formation of contrails, which are lines of clouds left by high-flying aircraft. The study involves Boeing's ecoDemonstrator Explorer aircraft and NASA's flying science laboratory, with the goal of collecting data to assess the impact of sustainable aviation fuel on contrail formation.
NASA is studying contrails to determine if more environmentally friendly aircraft fuels might reduce their formation.
The study involves Boeing's ecoDemonstrator Explorer aircraft, a 737-10, being followed by NASA's flying science laboratory, a DC-8. The 737 switches between tanks of conventional fuel and 100 percent sustainable aviation fuel while the DC-8 measures emissions and contrail ice formation. Research from NASA over the past decade has shown that using sustainable aviation fuels can cut particle emissions, and efforts are focused on matching the performance of conventional fuel without contributing more carbon dioxide.Airbus takes its long, thin, plane on a ten-day test campaignthat less than 0.1 percent of global consumption is SAF, which is considerably more expensive than conventional fuel while suffering from a lower energy density – bang per buck if you will.
