- Goal for this week: Decide whether to re-open the design space – seeking guidance
- Goal from last week: Set specific technical tasks for the next six months: not achieved
- If our plane has to fit perfectly within an existing airline operations regime, it has to fly at ~30,000 ft and mach ~0.78, similar to today’s Boeing 737.
- If this is the case, then the ducted fan design (see below) we’ve been considering probably makes a lot of sense because of the efficiency gains.
- But fitting into this regime requires a bunch of sacrifices.
- For example, if we’re willing to slow the plane from mach 0.7 to mach 0.55 or mach 0.5, which on a 300 mile flight might only make the flight 10 or 15 percent longer, we can potentially reduce energy consumption needs (costs) by 20 percent or more.
- Similarly, if we’re willing to fly at lower altitudes, we might further reduce energy costs.
- Some airlines might not like this. It could be like driving 40 MPH on the highway.
- But maybe for a new plane design it’s worthwhile.
Note: the boxes on the front part of the wings are ducts that house internal electric motors / fans
The major levers we’re considering pulling are:
- Flight profile
- Passenger cabin volume
- Baggage carrying limitations
We’re trying to figure out how to think about this. Our first step is going back to the airlines and asking more questions about which of these items are crucial and which can be adjusted.
