Advanced System Engineering - FIPSI BX4



Flying Innovative Personal Space Icon (FIPSI)

Advanced System Engineering founded by Bogdan Radu on Feb. 4, 2004, has invented the Flying Innovative Personal Space Icon. The aircraft is a concept hybrid-electric vertical take-off and landing (VTOL) two passenger personal land and air vehicle allowing the consumer to have the best use of both roads or air for traveling. The idea of his vehicle is to make true urban mobility available for anyone, regardless of your location, without the need for an airport or heli-pad and allowing one to change from road to air travel and back, at a moments notice.

Radu has invented two models, the BX4 and the WX4. The BX4 is a vectored thrust VTOL aircraft and the WX4 is a vectored thrust aircraft with a retractable and expanding wing on top of the vehicle to provide longer flight times. Both vehicles have a cruising flight speed of 45 mph (72 km/h) and a maximum road speed of 72 mph (116 km/h).

The reason Radu created an all-in-one land and air vehicle because if the aircraft were manufactured and sold to customers right now, the customer could use the vehicle without cities having to add any additional costly airport or heli-pads, time is not wasted traveling to and from purpose built landing pad areas, and there is no time wasted for check-in and waiting to board the aircraft.

The current urban air mobility (UAM) model which most companies are using claims that UAM will be quick, fast and a huge time saver for the passenger. However, how can urban air mobility save travel time when the passenger will be traveling from their home to the take-off area, then add the check-in time, then the wait for boarding, add to that - flying time, deboarding time and finally, the time it takes to travel from the landing area to work! Won't it simply be faster to drive your car to work than using urban air mobility? This is the question that Radu reminds the world to think about and to answer. Radu says he has the answer.

The simplicity and practicality of his BX4 eliminates the wasted time needed to travel to and from landing pads, and checking into and waiting for flights. That is, the BX4 is a true time-saver for urban air mobility and is not just a plan to get more airports built in the urban landscape which will continue to add time to the passenger's journey. This way, based on planned or unplanned needs of the consumer, the consumer can travel leisurely by road to local stores, fly on a weekend getaway, drive to work or fly over the rush hour traffic, when necessary, to be on-time to work.

There are at least three core ideas for the basis of the aircraft: innovation, versatility and ease of use. In addition, his design reduces the complexity of the aircraft, protects the passengers from vehicle components when not in flight mode and its design also protects the components from harm when not in flight mode. The estimated cost of this vehicle is ten times less than a helicopter.

The company sees many applications of this aircraft which include but are not limited to a personal air vehicle and road vehicle, search and rescue, escape vehicle due to any natural or man-made disaster, police, fire, general contractors, government, military, cargo, utility services and more. The aircraft can perform most helicopter transportation missions.

The BX4 is intended to be piloted manually but can function as an autonomous aircraft as well. For cargo use, the seats simply need to be removed. One the most important features of this aircraft is its ability to take-off and land anywhere without the need of any additional infrastructure.

The safety features include a parachute and the ability of the vehicle to retract its propellers and keep them protected while the vehicle is in storage, parked or in driving mode. The company plans to sell the aircraft to the end user.
