== Purpose of this page ==

This page defines the meaning of '''Technology Readiness Level 1 (TRL 1)''' and explains how it is used within the Collaborative Bee project framework.

It is designed to provide a shared reference before accessing the project-specific TRL 1 pages.

<div style="border-left:4px solid #1f3a5f; background:#f6f8fa; padding:12px; margin:16px 0;">
'''Objective:''' provide a clear and professional maturity framework for early-stage project documentation.
</div>

== What are Technology Readiness Levels? ==

'''Technology Readiness Levels''' are a structured scale used to assess the maturity of a technology.

They help project teams, contributors, partners and stakeholders understand whether a technology is still at the stage of scientific observation, concept formulation, prototype development, validation, qualification or operational use.

TRLs are useful for:

* structuring research and development activities;
* clarifying the maturity of each project;
* supporting technical reviews;
* preparing industrial development roadmaps;
* improving communication with academic, industrial and institutional partners;
* anticipating certification and validation work.

== Definition of TRL 1 ==

'''TRL 1 – Basic Principles Observed''' is the first maturity level of a technology project.

At this stage, the objective is to identify the scientific, physical, technical or operational principles that may support a future concept.

TRL 1 does not mean that a product, prototype or complete architecture already exists. It means that the first technical foundations have been identified and can be documented.

{| style="width:100%; border-collapse:separate; border-spacing:12px; margin:16px 0;"
|-
| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#f6f8fa; padding:12px;" |
'''Observe'''

Identify basic scientific, technical or operational principles.

| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#f6f8fa; padding:12px;" |
'''Question'''

List assumptions, opportunities, unknowns and early risks.

| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#f6f8fa; padding:12px;" |
'''Prepare'''

Create the documentation base before moving toward a formulated concept.
|}

== TRL 1 within Collaborative Bee projects ==

Within the Collaborative Bee framework, TRL 1 is used to document the starting point of each project in a consistent and reusable way.

For each project, TRL 1 should clarify:

* the mission or need addressed by the project;
* the basic principles that justify the concept;
* the initial assumptions;
* comparable technologies or references;
* the main uncertainties;
* the first technical and operational risks;
* the questions that must be answered before moving to TRL 2.

This approach supports continuity between academic, industrial and individual contributors.

== Expected outputs at TRL 1 ==

{| class="wikitable" style="width:100%;"
|-
! style="width:30%; background:#eef1f4;" | Output
! style="background:#eef1f4;" | Description

It provides a structured starting point before the project moves toward a formulated concept. Its role is to document the first principles, the initial assumptions and the key questions that will guide the next stages of development.

<div style="border:1px solid #cfd6dd; background:#f6f8fa; padding:14px; margin-top:18px;">
'''Next step:''' once TRL 1 is sufficiently documented, the project may progress toward '''TRL 2 – Technology Concept Formulated'''.

== Project overview ==

The '''Mini-Bee''' concept started from the idea of a low-cost aircraft combining vertical take-off capability, high mobility, hybrid propulsion and useful mission applications.

At this stage, the project was not yet a formulated technical concept. The objective was to explore whether a compact aircraft could combine the operational flexibility of a helicopter with simplified logistics and a more affordable architecture.

The earliest studies considered a hybrid aircraft with electric propulsion for VTOL phases and a thermal engine for cruise or power generation. These assumptions evolved significantly in later TRL stages.

== Concept origin ==

The early Mini-Bee idea was driven by several needs:

* provide high mobility without relying on conventional runway infrastructure;
* explore a low-cost aircraft concept;
* support missions such as air ambulance, rescue, emerging-country mobility and personal air transport;
* combine vertical take-off and landing with cruise flight capability;
* investigate a hybrid propulsion architecture;
* reduce the need for large battery capacity by using a thermal power source.

== Early mission framing ==

{| style="width:100%; border-collapse:separate; border-spacing:12px; margin:16px 0;"
|-
| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#ffffff; padding:12px;" |
'''Mobility'''

The aircraft concept aimed to land in a wide range of locations, not only on conventional runways.

| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#ffffff; padding:12px;" |
'''Low cost'''

Early requirements included a strong cost objective to make the concept accessible and useful.

| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#ffffff; padding:12px;" |
'''Useful missions'''

The early project logic included air ambulance, rescue missions and low-cost personal transportation.

|-
! style="width:35%; background:#eef1f4;" | Early assumption
! style="background:#eef1f4;" | Historical interpretation at TRL 0
|-
| '''Hybrid configuration'''
| Electric motors would support VTOL phases, while a thermal engine would provide cruise power and/or electrical generation.
|-
| '''VTOL capability'''
| Vertical take-off and landing were identified as a key differentiator for high mobility.
|-
| '''Cruise speed'''
| Early objectives mentioned a high cruise speed target around 300 ± 50 km/h.
|-
| '''Range'''
| Early objectives mentioned an autonomy target between 600 and 800 km.
|-
| '''Mass and capacity'''
| Early studies considered a larger aircraft concept, including 4 or 5 seats and an MTOW around 1550 kg.
|-
| '''Cost target'''
| Early requirements mentioned a low-cost objective below 100,000 €.

'''Historical note:''' these early assumptions belong to the pre-TRL concept phase. They are not the current Mini-Bee configuration.

== First hand sketches ==

The hand sketches helped define the first visual intuition of the aircraft: side view, front view and top view.

== Preliminary technical studies ==

'''Wing sizing intuition'''

An initial wing chord evaluation explored the relationship between wingspan, stall speed and wing chord.

| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#ffffff; padding:12px;" |
'''Thermal engine search'''

A first engine study examined the role of a thermal engine in a hybrid aircraft power architecture.

| style="width:33%; vertical-align:top; border:1px solid #cfd6dd; background:#ffffff; padding:12px;" |
'''Electric propulsion screening'''

Early electric motor comparisons were used to understand the challenge of VTOL power-to-weight ratio.
|}

== Wing chord evaluation ==

The initial wing evaluation considered a rectangular wing and used a lift equation to estimate the chord needed for different stall speed assumptions.

== TRL 0 development logic ==

The TRL 0 phase was about creating the project foundation before entering the formal TRL logic.

== Why TRL 0 mattered ==

TRL 0 mattered because it captured the first project intuition before formal technical maturity could be claimed.

It helped transform an idea into a project direction: a hybrid aircraft with VTOL capability, practical missions, high mobility and a need for technical validation.

This stage prepared the transition toward TRL 1, where the first basic principles of the Mini-Bee concept could be observed and documented.

== Transition to the next stage ==

<div style="border:1px solid #cfd6dd; background:#f6f8fa; padding:14px; margin-top:16px;">
'''Next maturity step:''' TRL 1 – Basic Principles Observed.
</div>

At TRL 1, the project moves from early intuition and exploratory material toward the identification of basic principles that justify a structured concept phase.
