Aliptera

Aliptera Inc. is developing Griffin, a four person VTOL aircraft concept. VTOL means vertical takeoff and landing. The website says the concept uses a lip wing design. The site does not give a head office city, so the location is not stated. The site's copyright runs from 2015 to 2024.

The site says Griffin has two lip wing pairs. A canard lip wing sits at the front and provides extra lift and stability. The main lip wing pair forms part of the primary wing. The site says the four quad rotors can tilt. If a rotor or drive fails, the aircraft changes to a three rotor setup.

The site says the lip wings help during hover by reducing the load on the rotors. It says they also improve efficiency and range in cruise. The site describes the concept as aimed at personal air travel.

The site shows a scale model of Griffin that can hover. It also shows the start of transition testing from vertical to horizontal flight. Videos are posted on YouTube, and the company shares updates on Facebook and LinkedIn.

The about page names Dusan Stan as president and CEO. Daniela Stan is vice president and CFO. Alexandru Stan is founder and IT expert. The site thanks academic contributors for research and computational fluid dynamics analysis. It also names affiliated groups, including EAA Chapter 65 and the Stoney Creek Hawks model aircraft club.

The contact page has a form for remarks, suggestions or comments. It invites people to write about themselves if they want to work on the team. The site has concepts, development and resources pages.

The contact page says visitors can get updates on development and can send remarks, suggestions or comments. The site describes the aircraft as a concept, with early hover and transition work shown in its video.
