It is easy to say that, although small electric aircraft are at last selling, they are a negligible part of the overall aircraft market. Mistake. They will work up from the bottom to be mainstream. Airbus, Boeing and Rolls Royce know this, but many others are sleeping through the future. Some of the successes are from small companies.
Amazing new technologies are in the pipeline. The new IDTechEx report, “Manned Electric Aircraft 2020-2030,” explains the significance of such things as distributed thrust with up to 30 thrusters, ionic thrust, rise-and-glide, cryogenic fuel cells, superconducting motors and powertrains and other routes to even airliners going pure electric. Regenerative propellers and solar/ supercapacitor bodywork will assist.
This is a story of three options:
1) The idea whose time has come – small fixed-wing pure-electric aircraft giving lower total cost of ownership, zero emission, nearly silence, off-grid charging – no fuel supply chain. They are needed for initial training of over 500,000 pilots over the next 20 years (Boeing). They may reverse the decline in leisure piloting by solving its problem – cost. All-hours fixed-wing flying taxis are in prospect and newly-viable, clean tourist and industrial flights. The leader, Bye Aerospace, rapidly gained an orderbook of over $165 million, yet this is under 1% of the addressable cumulative market for this subsector of the emerging manned electric aircraft business.
2) The certainty within 10 years – larger fixed wing electric aircraft: lower cost, more versatile, all hours. Power needed increases disproportionately with size, but the report predicts when larger e-aircraft are viable. Hybrids get there first but with some noise and emissions deficit. But can pure-electric alternatives to business and regional jets fly as fast? Can biofuels always be available where needed?
3) The glamorous – small vertical take-off VTOL aircraft are weird and speculative. Participants target city flights from locations not currently approved for flying. Power failure is usually catastrophic: they fly too low for a parachute and do not glide. Solving the safety, regulatory, systems cost, air traffic control and other problems needs time. Flying from your garden is some way away. Patient, wealthy developers like Uber are at an advantage here. Long distance hybrid VTOL aircraft for fast turnaround in regular airfields are an interesting alternative market.
