LightShip 4 Now Starting Customer Evaluation

[Rory (Lightship Team)]

Add to the discussion with the alternate (but approximate) formula:

FD = 1/4 AV^2

hey @redbaron , no simplifying our CdA! It took us years to make it worth breaking out )

The LightShip attracts attention. As people walk up to it I am using a new approach to initiate a discussion about this new RV.

I had a window cling banner made up at Signs.com and stuck it on the entry door of LightShip 4. When the question arises by a newby showing interest in the LightShip I ask them to consider the equation. The Q & A flows so easily from the equation.

Interesting how the window cling reflects around the LightShip windows.

@turbopilot , do you experience a noticeable performance difference in your plane between dry cold conditions and humid hot conditions? Theoretically there could be a small percentage point reduction in air density (“p”) from cold desert to hot coastal but curious if it translates into noticeable efficiency gains…

Of course your formula is the most accurate.

For my current inventory of Diesel pushers, 1 ton dually and various large trailers, approximate satisfies curiosity.


In all seriousness though, I like the approach @turbopilot is taking because that will definitely be a conversation starter.

Haha yes!

Humidity has a small impact on air density. Altitude and heat are the major variables. Every aircraft has a section in the manual about adjusting performance for density altitude. Density altitude not only impacts aerodynamics but also has a big impact on efficiency and power of most internal combustion engines. Pure EVs and turbocharged ICE engines are not significantly impacted by density altitude.

Haha yes!

It definitely works for the "liberal arts" majors. They have no idea what it means.
