1. Conventional turbofan aircraft

​

In contemporary medium- and long-haul aircraft the power for propulsion is generated by gas turbines paired with a ducted fan (turbofan) or an unducted fan (turboprop).

​

Integration of Open AG-Cycle into aircraft’s gas turbine engine will allow to reduce fuel consumption by around 60%, and extend aircraft’ flight range by around 25%. Integration of Closed AG-Cycle where the water is recuperated from water vapor of exhaust fumes, rather then stored in water tanks, will reduce fuel consumption by around 55%, and double flight range.

​

Substituting traditional power plant of aircraft with a serial hybrid Supercritical Carbon Dioxide (S-CO2) power plants enhanced with AG-Cycle is expected to improve aircraft’s fuel economy by around tree times, and expand flight range by around 2.7 times. Particularly, 2017 Boeing 737 MAX 9’s flight range would rise up to around 17,700 km., if equipped with AG-S-CO2.

2. EVTOLs

​

Electric vertical take-off and landing aircraft (EVTOLs) enhanced with AG-Cycle will not only replace traditional short-haul aviation and substantially take over medium-haul aviation, but also create an entirely new and affordable weekday and weekend air-commuting segment, that will expand the practicable weekday commuting radius up to 200 mi, and and that of weekend commuting up to 1,100 mi.

​

Estimates show that AG-EVTOLs based on 5 seat Lilium jet will fly at a speed of around 220 MPH for distances up to 600 mi and longer. People will be able to work in big cities and reside within 200 mi radius suburb zone, because one way air-commuting by AG-EVTOL will only take around an hour for a 200 mi distance. It is estimated that the average annual price of this service will not exceed $23,000. Owners having vacation properties in distances up to 1,300 mi will be able to travel there on weekends, fully enjoying their full-fledged night rest  for an affordable price.

​

Today, many companies are working on EVTOLs. Estimates show that at least for one existing EVTOL, 5 seat Lilium jet, the weight of the AG-power-plant based on externally fired gas turbine generator and a pack of ultra-capacitors will not exceed the weight of EVTOL’s original battery pack, and it will also have substantially higher power, boosting the prototype’s cruise speed.
