Founded by Petros Tsolis (CEO, engineer, pilot), Stuttgart Aerospace is prolific in creating multiple unique electric vertical takeoff and landing aircraft (eVTOL) concept designs for a wide range of uses, from personal air travel, to urban air taxis, cargo transportation, fire fighting and to emergency medial service (ems). We've counted at least seven different eVTOL designs that Stuttgart Aerospace has designed. The reason Tsolis started the company, is to create clean and safe eVTOL aircraft for Urban Air Mobility (UAM) and to reduce the time and stress that people currently experience, when driving cars to work. The company is still in the planning stages to manufacture eVTOL aircraft and are looking for investors. 
  
Stuttgart Aerospace argues the point that the key to make Urban Air Mobility practical, useful, affordable and made into reality as soon as possible, is that the entire UAM industry needs to focus on using our current infrastructure, from our personal homes (apartments, condos), to all the buildings and structures in our cities, instead of building multiple costly and time consuming vertiports in every city. This way, as soon as eVTOL aircraft are certified airworthy and safe, the general population, businesses and governments, can immediately take advantage of electric UAM in all cities. 

The company states that using our current infrastructure for Urban Air Mobility will be a key factor in keeping the cost down to the consumer and businesses, who want to use urban air travel to their advantage. Because of this, the company has proposed that their aircraft will be in direct competition with car manufacturers. A Stuttgart Aerospace online video reveals their Eolos 2 aircraft will be able to land in very small spaces, such as landing in a courtyard next to a building or in a standard parking space. The video also shows that they propose their aircraft will be able to negotiate very close flying next to buildings and skyscrapers, in any city. 

The Eolos eVTOL aircraft is a sleek modern design and is slated to be the first production UAM aircraft for the company. Its canopy slides back allowing for ease of entry and exit of its passengers. The aircraft will be easy to operate having both piloted or autonomous options for navigating in an urban environment. The aircraft has has an estimated cruise speed of 100 km/h (62 mph), estimated range of 50 km (31 miles) plus reserve, has a low acoustic signature, and the battery can be charged in 30 minutes. The flight range is expected to be improved over time as battery technology becomes more advanced.

The aircraft has multiple safety devices including an emergency whole aircraft rescue parachute systems, pop-out flotation devices and can land with only two of its motors running. Another safety feature is there are no moving parts on the outside of the aircraft. This means that no one could ever get hurt from this aircraft during landing, takeoff, idling or when parked. 

The company expects the aircraft to be used for a personal air vehicle for the consumer. The company has not provided any projections when production models are expected to be made; however, one of the company's prototypes is projected to debut in the fall of 2021. 

Specifications:

• Aircraft type: eVTOL aircraft 
• Piloting: Piloted or autonomous 
• Capacity: 4-6 passengers 
• Cruise speed: 100 km/h (62 mph)
• Cruise altitude: 305 m (1,000 ft)
• Estimated flight time: 45 minutes
• Estimated range: 50 km (31 miles) plus reserve
• Payload weight: 480 kg (1,058 lb) 
• Propellers: 4 propellers
• Electric Motors: 4 electric motors 
• Canopy: Sliding canopy 
• Power source: Batteries, batteries fully recharge in 30 minutes. The aircraft can accept multiple power sources, such as a turbine engine which creates electricity for the propellers. 
• Windows: Panoramic windows with wrap around window design allowing forward, left, right and top visibility, for spectacular views 
• Landing gear: Aircraft lands on 4 fixed landing feet 
• Safety Features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers and motors on the aircraft so if one or more motors or propellers fail, the other working motors and propellers can safely land the aircraft. The aircraft can land with two of its motors running. Has an emergency parachute if there is a complete power failure. There are no moving parts on the outside of the aircraft which means that no one could ever get hurt from this aircraft during landing, takeoff or when parked.
