Discussion Overview
The discussion revolves around the Moller SkyCar, specifically focusing on the use of Wankel rotary engines for powering ducted fans to achieve lift. Participants explore the technical aspects of lift generation, engine performance, and safety concerns related to the design and operation of the SkyCar.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant inquires about the lift capabilities of Wankel rotary engines when used with ducted fans.
- Another suggests a method for estimating lift by calculating pressure and momentum changes, while also noting the potential need for a gearbox and expressing skepticism about the design's safety.
- A participant emphasizes that lift generation is highly dependent on the specific design of the ducted fan, indicating variability in performance and power requirements.
- Concerns are raised about the reliance on GPS and computer systems for operation, with one participant expressing distrust in automated systems for flying at high speeds.
- Another participant mentions the redundancy in the engine design, stating that there are two Wankel engines in each pod, with one serving as a backup.
- A humorous comparison is made regarding safety in aviation, contrasting the SkyCar with flying an open cockpit biplane.
- Further humor is introduced with a playful comment about the implications of losing wings on a biplane.
Areas of Agreement / Disagreement
Participants express differing views on the safety and feasibility of the Moller SkyCar's design, with no consensus reached on the reliability of its automated systems or the adequacy of its lift capabilities.
Contextual Notes
Participants note the variability in ducted fan designs and their performance, indicating that assumptions about lift and engine power may depend on specific configurations not fully explored in the discussion.
