Founded on July 13, 2022, Sacdeeil Aerospace Private Limited is a company located in Puducherry, Tamilnadu, India. The company is in the business of designing and manufacturing short and long range passenger and air cargo electric vertical takeoff and landing (eVTOL) and hybrid-electric VTOL aircraft for advanced air mobility (AAM).

The company's main focus is sustainability, efficiency and safety of their aircraft. The company is aiming to utilize renewable energy sources, produce minimal emissions from their aircraft, to maximize fuel efficiency and reduce operating costs. The company also aims to design and manufacture electric fixed-wing aircraft. Currently the company's research and development, assembly area and test facility is located at the Puducherry Airport in India.

VM8 passenger eVTOL multicopter concept design aircraft
The VM8 is a two passenger eVTOL multicopter concept design aircraft made for advanced air mobility (AAM). The multicopter is planned to be a compact aircraft yet packed with advanced autonomous piloting and avionics. The aircraft will have a canopy over the cockpit providing spectacular views for the passengers. The aircraft will also have room for a small amount of luggage.

The aircraft has an expected cruise speed of 150 km/h (93 mph) and has an anticipated flight time of 40 minutes. The estimated maximum takeoff weight of the multicopter is 720 kg (1,587 lb). The aircraft will have eight propellers, eight electric motors and will be powered by battery packs. The aircraft will be designed with a carbon fiber composite fuselage for a high strength and low weight ratio. The aircraft will have fixed skid landing gear.

The multicopter has distributed electric propulsion (DEP) meaning the aircraft has multiple propellers and multiple electric motors on the aircraft, so if one or more propellers or some electric motors fail, the other working propellers and electric motors can safely land the aircraft. DEP provides safety through redundancy for passengers or air cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.

This particular multicopter aircraft design reduces the complexity of the aircraft which increases safety exponentially, reduces manufacturing costs, reduces maintenance costs, reduces the cost of purchasing the aircraft and increases the service life of the aircraft. Reducing complexity of eVTOL aircraft also reduces weight which then in turn, increases the range of the aircraft.

In addition, all the specifications on this web page are estimated. The actual flight specifications will only be known when a pre-production prototype is made and flight tested.

Future developments
The company has ambitious plans for the future. The company is planning on designing and manufacturing a two, three, five and nine seat eVTOL aircraft. Some of the large models might be powered by a hybrid-electric power source. Each of their models will also be reconfigurable for air cargo service.

DEP provides safety through redundancy for its passengers or cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy. Having multiple redundant systems on any aircraft decreases having any single point of failure.
