An Aircraft With Fewer Moving Wing Parts
When moving wing parts are removed, wing and fuselage production can move toward automated manufacturing. The target is to bring aircraft cost down to one-tenth of conventional aircraft.
Fewer parts. Lower cost. From cargo to people.
When moving wing parts are removed, wing and fuselage production can move toward automated manufacturing. The target is to bring aircraft cost down to one-tenth of conventional aircraft.
Software determines attitude and flight-mode transition across hover, transition, cruise, and glide.
Unpowered glide directly satisfies the controlled emergency landing requirement of FAA AC 21.17-4. Even when propulsion is lost, autorotation and differential drag preserve directional control authority.
By reducing moving control surfaces, Lambda reduces parts, failure points, certification items, and manufacturing processes at the same time.
The target aircraft cost of one-tenth, 500 kg repeated operations, and the Busan-Fukuoka 59-minute example all point to the same cost structure.
Even when power is lost, the aircraft is designed to manage direction and trajectory through autorotation and differential drag.
Hover takeoff and landing, transition, cruise, and emergency descent. One aircraft performs all four.
Payload, distance, takeoff and landing space, arrival time, failure behavior, and cost per trip come first.
Mode-aware control keeps flight behavior within defined boundaries, makes it repeatable, and makes it explainable through operation logs and test data.
VTOL access, long-range cruise, repeated cargo operations, and low maintenance are not separate features. They are one design problem that creates the same operating cost structure.
Simulation, control, airframe, safety behavior, and IP are developed together to lower aircraft cost, maintenance cost, and improve utilization at the same time.
Lambda IP protects hover takeoff and landing access, deterministic flight, fixed-pitch low-maintenance rotors, a no-control-surface airframe, unpowered glide, and differential-drag control as one architecture.
A propulsion architecture that satisfies both point access and mid-mile cruise efficiency.
Flight modes stay within defined boundaries, are repeatable, and can be proven through operation logs.
Removing moving wing parts reduces mechanical complexity and maintenance items at the same time.
Even in propulsion-loss scenarios, the aircraft is designed to switch into autorotation and glide modes and perform controlled descent using rotor-by-rotor drag differences.
Even when propulsion is lost, the aircraft manages attitude and trajectory through its own glide performance and rotor-by-rotor differential drag.
The simple airframe structure dramatically lowers aircraft cost.
Minimizing moving wing parts and mechanical elements reduces inspection, replacement, service items, and maintenance burden.
Predictable and repeatable flight behavior creates a certification structure where safety can be demonstrated.
Beyond simple aircraft sales, it evolves into an air logistics asset that creates continuing revenue through repeated operation.
The same loop that moves Lambda also applies to humanoids and autonomous machines. Define the mission, simulate the motion, close the control loop, and design the machine for its operating conditions.
SDA expands a software-defined aircraft into an operating asset. A 100 million KRW aircraft, 5 billion KRW lifecycle revenue, 50% target margin, and repeat revenue through fleets, operating rights, Flight OS, and MRO.
Development collaboration for new-technology aircraft and aerial robots based on SDA asynchronous tilting and Flight OS.
UAM city simulation, aircraft demonstration, and route demonstration.
A network of about 25 patents protects the new technology based on the asynchronous tiltrotor patent.
Aircraft structure, Flight OS, operating corridors, IP licensing. Collaboration can begin from any point.
Lambda begins with air logistics. The bigger picture is mission-defined machines for the physical world.
Receivepower has been building intelligent robots since 2019. From walking humanoids to flying robots, we build machines moved by Physical AI.
It creates a repeat-revenue structure that expands beyond simple aircraft sales into fleet ownership, corridor operating rights, MRO, Flight OS, continuing airworthiness data, and regional JVs.
Receivepower works on Physical AI technologies that move real machines. Robot middleware, industrial control, coordinate systems, sensor fusion, virtual space, vision, manipulation, contact control, AI models, workcells, factory data, safety, and engineering systems are connected into one execution system.
Receivepower IP simplifies the aircraft structure, creates predictable safety behavior in emergencies, and lowers the cost of repeated operation.
Every rotor tilts independently.
Hover thrust devices convert into cruise thrust to secure long-range air logistics efficiency.
Propulsor placement and differential-thrust control replace moving control surfaces. Stagger-based virtual control surfaces are explained in the detailed technology section.
SDA transitions by separating inner and outer propulsor groups, tilting them in stages, and transferring control authority by flight mode.
Eight propulsors lift the aircraft with hover thrust.
Some propulsors begin transition first.
Hover thrust and cruise control are handled together.
The remaining propulsors move into the cruise direction.
After transition, full cruise control authority is secured.
Fixed-wing cruise secures range and economics.
By removing moving wing parts, reducing parts toward one-hundredth, and turning certification into a procedure, Lambda proves the path first.
Route, payload, arrival time, failure response, and cost per trip come first. The aircraft is designed to satisfy those operating conditions.
The first class to verify asynchronous tilt, unpowered high-lift devices, virtual pitot, and hybrid power buffer on a real aircraft.
A lightweight class that proves Lambda architecture’s core technologies first in actual flight.
An intermediate class for BVLOS uncrewed cargo operation. Before the 500 kg mid-mile cargo aircraft, this line accumulates certification, operation, and maintenance data in real corridors.
The main class for uncrewed mid-mile cargo. It is not a one-time aircraft sale, but a fleet operating asset that repeatedly sells 500 kg-class throughput.
The passenger type is the follow-on product on the AC 21.17-4 powered-lift track. Uncrewed cargo fleet data builds the safety case, and Flight OS leads to remotely supervised and uncrewed autonomous passenger transport.
A view of expansion from repeated uncrewed cargo operation data and safety architecture into powered-lift passenger aircraft and autonomous passenger transport.
Receivepower first secures economics and operating data through cargo operation. SDA’s repeatability is validated where ground and maritime transport lose time, then that data builds the path toward crewed flight.
Lambda is air logistics equipment for that gap. It provides direct aerial access where lost time erodes product value and safety: island logistics, mountain supply, industrial cargo, and urgent delivery.
Air logistics opens only when aircraft price, energy, maintenance, safety, certification, and utilization align together. Lambda reduces these cost layers through airframe structure and operating software.
